The monitor gets the wrong signal from the computer (refresh rate too high or scan rate too high )
check the screen refresh rate from Display properties / Settings tab / Advanced button / Monitor settings
worse case: damaged hardware

I have an Emachine D620 5133 Laptop that the screen stays solid white when powered up, any ideas?


No ideas

Just definite facts

Problem is;
A) Graphics chipset
Or.
B) Video Cable
Or,
C) Screen Inverter
Or,
D) LCD screen

Diagnose
LOT of reading ahead.

1) Graphics chipset:

Connect a VGA monitor to the blue VGA port, on the right side of the laptop.

http://www.geeks.com/largePic_all.asp?invtid=D620-5133-OB&pic=D620-5133-OB-box.jpg

This is a general example of a VGA port (Connector), and VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA Cable.

Turn the monitor on. If a CRT type allow it to warm up
Turn the monitor on.
By factory default settings the display should show on the external monitor.
IF not;

There are at least 3 display options;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the Same time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

No display, (Or solid white), on external VGA monitor, suggests problem with graphics chipset. If this is the problem post back in a Comment.

Good display?
Problem is Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

There are no eMachines D620 service manuals, available on the internet for free that I have seen. Supposedly a few paid for versions, but I have my reservations about that.
(Probably a Generic User Guide, which you can get for free)

I also have never worked on this model yet.

But this isn't rocket science, and this isn't 'my first rodeo'.

2) Video Cable:

The Video Cable plugs into the motherboard, in an area under the Keyboard, and under the Palm Rest Cover.

Judging by;
A) Top View of motherboard,

http://www.ebay.com/itm/eMachine-D620-Motherboard-48-4BC01-011-MBN240100-08226-1-Yukon-MB-/121076931939?pt=US_Motherboard_CPU_Combos&hash=item1c30bf5d63

Set your mouse cursor in the middle of the photo. This enables the Zoom In feature.

Looking at the rectangular metal plate, with the opening in the middle of it; come from the Top/Left corner.

See what appears to be a fairly long white strip?
That is where the Video Cable plugs into the motherboard.

Now here is the D620 with the Keyboard removed. (And Display Assembly),

http://www.ebay.com/itm/eMachines-D620-Motherboard-CPU-base-assembly-/110847874891?pt=Motherboards&hash=item19cf0c574b

Here you see the white connector again.
Middle, and towards the Top; in the small rectangular opening.

The Palm Rest Cover has to be removed, to access the Keyboard Cable's motherboard connector. This connector.

Going on....
The Video Cable then goes up by the left Hinge, and then up into the Display Assembly.
From there the main portion of the Video Cable, connects to the back of the LCD screen.
There is also a separate small cable, coming from the Video Cable; that connects to one side of the screen Inverter.

Example of the Video Cable,

http://www.ebay.com/itm/eMachines-D620-LCD-Video-Cable-50-4BC03-021-/130862506637?pt=US_Video_Cables_Adapters&hash=item1e7803628d

The white connector you see at the bottom, with the black pull strip; is the motherboard plug connector.
The small cable extending to the Right, connects to the screen Inverter.
The large connector shown at Top, connects to the back of the LCD screen.

Just from normal repeated opening, and closing of the laptop; the Video Cable may become pulled on, and/or pinched.
This can cause a loose connection at the motherboard side, or LCD screen side.
Screen Inverter cable connection may be pulled loose also

Can also cause damage to the Video Cable. Stretched/Broken wires

The procedure is to;
A) Remove ALL power. Remove the AC adapter (Charger), and Battery.

B) PHYSICALLY check to see if the motherboard connection is tight. Try to plug in tighter.
Reinstall power. Turn laptop on see if this was the problem.

No?
Remove all power again. This time remove the Display Bezel, and see if the Screen Inverter cable is connected tightly.
At this point it is just going to be a visual observation, and record.

Next is to check the LCD screen connection of the Video Cable, and it may loosen the Screen Inverter connection, anyway.

[The plastic frame in front of the LCD screen is the Display Bezel,

http://www.ebay.com/itm/eMachines-D620-LCD-Screen-Bezel-41-4BC01-001-/300798380595?pt=UK_Computing_Other_Computing_Networking&hash=item4608fb0a33 ]

If plugging the connections of the Video Cable in tighter, does no good; the Video Cable is then checked for continuity.
A multimeter is used, and set on OHM's. (1K)

Electricity is sent through each wire. The reading itself isn't as important, as just seeing IF there is a reading.
No reading indicates stretched/broken wire.
You can take the Video Cable, down to the nearest small computer repair shop; and have the resident tech check it out for a few bucks.

The Video Cable MUST be ruled out as the problem, before going on. Otherwise you may be buying parts needlessly.
(LCD screen? Around $70 to $100. You have seen the price of a Video Cable)

Video Cable proves to be good? Go on.

3) Screen Inverter:

The screen Inverter is located behind the Display Bezel, and mounted to the bottom of the LCD screen. (Screen Frame)

To test a screen Inverter requires a sensitive multimeter. Read fairly expensive,

http://www.fonerbooks.com/test.htm

Do to this, the ease of access to replace, and the general low cost; the screen Inverter is just replaced,

http://www.ebay.com/itm/LCD-Power-Inverter-Board-for-eMachines-D620-Backlight-Replacement-for-Screen-/120819595221?pt=US_Laptop_Screens_LCD_Panels&hash=item1c2168b7d5

If this doesn't repair the problem, the problem is the LCD screen.
Replace.

I can guide you, and I believe step by step; if you wish to attempt repair.

Display divided into 3 parts


LCD screen cracked, and Three even strips going across? Doubtful. Haven't seen it but I always have my mind open.

Three strips that are irregularly shaped? Look like glass that has cracked?
'Jagged edges'?

LCD screen is broken.

Three even strips indicates to me, that there may be a problem with the Video Cable. Then the screen Inverter is next in the diagnoses.
My money is on the Video Cable.

ALL power removed, Anti-Static Precautions FOLLOWED, I would check out the graphics chipset first.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.
Left rear side. This is an example of a VGA Cable, and VGA connector. (VGA port on a laptop ),

http://en.wikipedia.org/wiki/VGA_connector

(Color of connector does Not matter. It is generally Blue, though)

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

There are at least 3 display options available;
1) Laptop internal monitor ONLY
2) Laptop internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the F5 key. (The F5 key is the Display Toggle-Over key)

No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

Is the display on the external VGA monitor, the same as the internal monitor of the laptop?

Problem is the graphics chipset.

Display is fine on the external VGA monitor?
Problem is the Video Cable, screen Inverter, or LCD screen.

Video Cable:

A) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-14.jpg

Switch Cover removed, Keyboard removed. Shows you where the Video Cable plugs into the motherboard.

B) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-21.jpg

Palm Rest Cover you can see the white rectangular connector, for the motherboard side of the Video Cable, at the top left.
It's above the black cable, and near the screw hole.

The Video Cable leads from the motherboard, up through the left Hinge, and into the Display Assembly.
From there it connects to the screen Inverter, and back of the LCD screen.

http://www.ebay.com/itm/Toshiba-Satellite-A105-6017B0050801-LCD-Video-Cable-Genuine-OEM-Laptop-TESTED-/290754851160?forcev4exp=true&forceRpt=true

In the photo, (You can hover your mouse cursor on it to enlarge), the right side connector plugs into the back of the LCD screen.

The black connector to the far left connects to the motherboard.
The small white connector at the top with the Red, Green, Black, etc wires, connects to the screen Inverter.

(The small Black cable, that comes out from the black motherboard connector, is a Ground wire )

Due to the close proximity of the Video Cable to the left Hinge, it can be pulled on from just normal opening, and closing of the laptop over time.

This means the Video Cable connection on the motherboard side could be loose, or the LCD screen side, or both.

The diagnoses is to PHYSICALLY check BOTH connections. A loose connection at the motherboard, or at the back of the LCD screen could be so small in distance, that you will not see it with the human eye.

Could also result in damage to the Video Cable.
View the Video Cable with the Switch Cover removed, and see if there are any obvious signs of damage to the sheath of the cable.

If there is there could be damage to the tiny wires inside the Video Cable. (Stretched/Broken)

Use a multimeter set to OHMs, to check all wires inside the Video Cable for continuity, or have a 'Mom and Pop' computer store check it for a few bucks, or replace the Video Cable.

Video cable connections are tight? Video cable continuity check checks out OK?
Screen Inverter.

The test for a screen Inverter is to use a sensitive multimeter.
Read fairly expensive.

http://www.fonerbooks.com/test.htm

Not having access to a sensitive multimeter that you can use, means just replacing the screen Inverter. Seems like 'part changing', and it is, but you have to work with what you've got.

http://www.sparepartswarehouse.com/Toshiba,Satellite,A105,Laptop,Inverters.aspx

Find THE model number for your laptop, and the correct screen Inverter. A screen Inverter, and an LCD screen are a MATCHED unit.

Screen Inverter is checked out to be OK, or replaced, and symptoms are still the same, the problem is the LCD screen.

Remember, the first part of the diagnoses was to see if the divided parts were EVEN going across, or jagged and irregularly shaped.

Jagged in shape, and not even strips going across, means cracks in the LCD screen.
Replace.

HP pavillion dv9000 has black horizontal lines across screen and looks like a snowy background


Sounds like the screen is going bad. Isolate the problem by plugging an external monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker to plug to the laptop. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the Borrowed monitor does not show the black lines and snowy background, that proves your video card is ok and the problem is your lcd screen. If the borrowed monitor shows the same black lines ans snowy background it means your video card inside the computer has the issue.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Video on my toshiba L455=s5009 comes on for a few seconds then blacks out


From your brief diagnoses stated, it sounds like a bad Video Cable.

The Video Cable routes from the motherboard, across one edge of the Fan Assembly, and under the left Hinge assembly,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-Pro-L450-L455/big-body/laptop-disassembly-19.jpg

With just the usual opening, and closing of the laptop, the Video Cable's sheath may be damaged. This means the tiny wires inside the sheath may be damaged.
(Stretched/Broken)

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-Pro-L450-L455/laptop-disassembly-1.htm

http://www.laptoprepairparts.com/html/details.asp?ref=1860&category=cables

Or it may be the screen Inverter that is damaged, or going out,

http://mcccomputers.com/shop/lcd-inverters/3666-new-toshiba-satellite-l455-s5009-l455-s5045-lcd-inverter-pk070006t20-k000087330.html

Or the LCD screen assembly.

Could be the graphics chipset.

Diagnose.

1) Laptop OFF, monitor OFF, connect an external VGA monitor to the laptop's VGA connector, on the back of the laptop.

[ RBG (Monitor) port ]

You can use a CRT monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable, for the external VGA monitor.

[ Example of a VGA cable, and a VGA port (Connector),

http://en.wikipedia.org/wiki/VGA_connector ]

Turn the external VGA monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the external monitor should show the display, also.
IF not;
1) Press, and hold down on the Fn key, and simultaneously tap on the F5 key. (The F5 key is the Display toggle-over key)

Not showing on the external VGA monitor? Perform the above procedure again.
There are several display options.

External VGA monitor also show the same symptoms?
Bad graphics chipset. Replacing the motherboard is the most cost effective method, and easiest method.

External VGA monitor does Not show these symptoms?
Problem is the Video Cable, or screen Inverter, or LCD screen.

Due to movement of the LCD screen, which means movement of the Video Cable, my money is on a bad Video Cable.

(A Video Cable can be unplugged partially, real easy, on the back of the LCD screen.
It MAY look plugged in tightly, but may not be.

It can also be unplugged real easy when assembling the Display Assembly, to reinstall back on the laptop )

Check the Video Cable's wires with a multimeter. Perform a continuity check of all wires in the cable. (Multimeter set to Ohms)

Have an assistant also gently wiggle the cable, as you are testing. See if there is an intermittent break, due to a stretched/broken wire.

Or just buy a replacement Video Cable, and use it.

Keyboard lights up screen stays black....after inserting recovery disk screen still remains black...


Would like you to attach an external monitor for a diagnoses.

A VGA monitor.
Can be a CRT monitor that resembles a small TV, or a flat LCD screen monitor, that has a VGA cable attached,

http://en.wikipedia.org/wiki/VGA_connector

1) Laptop OFF, monitor OFF, attach the VGA cable of the monitor to the laptop's VGA connector.

[For the HP Pavilion dv6000z Notebook PC, the VGA connector is on the Left side at the Rear. Second port from the rear. 15 pins.
3 rows of 5]

2) Turn the monitor on. If a CRT style allow it to warm up.
3) Turn the laptop on.

By default the display should show on the external VGA monitor.

If not, press, and hold down on the FN key,
(Second key from the left, on the Bottom row on the Keyboard),
and tap on the F4 key.
(Top of Keyboard towards the left)

Still no? Hold the Fn key down again, and at the same time tap on the F4 key.

There are 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

IF, the display shows up on the external monitor, and if it is OK, the problem lies in the Display Assembly, and/or the Video Cable.

More on that in a moment.

IF, the display does Not show up on the external monitor, or if it is garbled, the graphics chipset is bad.

HOWEVER, there is a problem with the graphics chipset, for the dv6000 series of HP Pavilion Notebook PC's.
More specifically it isn't actually the graphics chipset itself, but the mounting of the graphics chipset to the motherboard.
More on this in a moment.

External VGA monitor shows a good display;
Video Cable:
The video cable is checked for apparent damage first, and at the same time, see if it's connectors are tightly plugged in.

On one end, the video cable is plugged into the motherboard.

(ALL power removed, AC adapter { Charger} and Battery, the Switch Cover is removed, and the Keyboard, far enough to lay it back out of the way. Keyboard Cable still attached to motherboard. The Display Cable is the one to the Far left, right under the left side of the LCD screen. The cable next to it, to the immediate right, is the Microphone Cable )

The video cable routed from the connection on the motherboard, up under the left Hinge Cover, and into the Display Assembly, where it then attaches to the Back of the LCD screen.

THIS connection must be checked also.

{ Just gave advice similar to this earlier. The asker's problem turned out to be a loose video cable connection, on the back of the LCD screen }

Examine the sheath of the video cable. See if there are signs of damage. If so the tiny wires inside the cable could be damaged.
Apparent damage or not, you may want to remove the video cable, and perform a continuity check with a multimeter. (Ohm's. Check each wire in the cable)

Video Cable connections prove to be tight, video cable continuity check proves video cable is OK, move on to the screen Inverter.

Primer:
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.

The Backlight is a CCFL for an HP Pavilion dv6000z Notebook PC.
[It is 2mm Wide, and 334mm Long. Or a little thicker than 1/16th inch Wide, and a little over 13 inches Long ]

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

A screen Inverter is used to convert power (Electricity) from the laptop, FOR the Backlight, and LCD screen.

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Example of a screen Inverter for a Pavilion dv6000z Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&products_id=560

The thin plastic frame that surrounds the LCD screen, and is in front of the LCD screen, (Resembles a picture frame), is the Display Bezel.
The screen Inverter is located behind the Display Bezel, and at the bottom of the LCD screen area.

How do you fix a white screen for a dell Inspiron 1100 lap top?


White LCD screen in a Dell Inspiron 1100 Notebook PC?

1) Loose connection of the video cable TO the LCD screen, and/or loose connection of the video cable TO the motherboard.

2) Bad LCD screen

3) Bad motherboard. (More specifically a bad graphics chipset)

To start the diagnoses to find out what the problem is, you will require an external monitor.

This monitor can be a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
(A CRT monitor is a VGA monitor also)

Example of a VGA cable, and a VGA port, (Connector on computer),

http://en.wikipedia.org/wiki/VGA_connector

The VGA port is on the back of an Inspiron 1100 Notebook PC.
It is Blue in color.

A) Laptop OFF, monitor OFF. Connect the VGA cable of the external monitor, to the laptop's VGA connector (Port)

B) Turn the external monitor on. If a CRT style allow it warm up.
Turn the laptop on.

By default, (Factory setting), the external monitor should show the graphics of the laptop.

IF Not;
There are 3 options available,

1) Internal monitor of the laptop - ONLY
2) Internal monitor of the laptop, AND external monitor
3) External monitor - ONLY

If there is NO display on the external monitor, (Display; To include a white screen);

A) Press the Fn key, and hold it down. Now tap the F8 key. (F8,CRT/LCD)

Still no display on the external monitor? Press, and hold down on the Fn key, and tap the F8 key again.

IF, the external monitor shows a white screen, Stop.
You have a bad graphics chipset. Option is to replace the motherboard.

IF, the external monitor shows graphics just fine, diagnose further.

A) Look to see if the Video cable is plugged in tightly to the motherboard, AND connected tightly to the LCD screen.

Dell Support > Inspiron 1100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

Click on - Display
Under the heading - Display Assembly, look at the partial 'photo' under the number 8.

On the left side where it shows two Philips head screws removed, is the Video Cable. Pinkish wire wrapped around a Light Blue wire.
Look at Number 9.
The display-feed flex cable is the Video Cable.

Make sure it is plugged in tightly to the motherboard.

Now go down to Number 10.
In the exploded drawing the number 7 points to the Video Cable.
(display-feed flex cable)

Shows the Video Cable disconnected from the motherboard, and going up to the back of the LCD screen.

Scroll down to the heading - Display Panel. This shows the connection of the Video Cable to the LCD screen.

Also;
The Video Cable runs through the left Hinge Cover.
Repeated opening, and closing of the laptop, may have damaged the Video Cable.

Observe the sheath of the Video Cable. (Outside wrap)
Does it appear damaged? Pinched? Torn?
Even if it does not, I suggest performing a continuity test with a multimeter.

Multimeter's function knob is set to Ohm's. (Omega symbol)
Positive probe lead (Red) is touched to one end of a wire going through the Video Cable.
Negative probe lead (Black) is touched to the other end of the wire.

Do not be concerned at this time with the Ohmage. Concern is to see if ANY reading comes up, not how much.

Perform a continuity check on all wires in the Video Cable.
(An economical, yet decent enough multimeter for this test, can be purchased for around $5 to $12. A multitude of store carry them. An auto parts store is but one example)

Video cable checks out?
The next suspect is the LCD screen.
However, read on.

Primer:
An LCD screen does not produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) is used to convert the power (Electricity) from the laptop, for the LCD screen, and Inverter.

90 PERCENT OF THE TIME the fault is the Inverter.

Example of a screen inverter for a Dell Inspiron 1100 Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=547

An expensive (Read - Sensitive) multimeter can be used to check a screen inverter. Not something everyone has laying around, or access to. In this case I would suggest replacing the Inverter.

(The screen Inverter is also easily accessed, AND much cheaper in comparison, than the LCD screen. Again, 90 percent of the time the fault is the Inverter )

IF, the Inverter does not cure the problem, then the problem is the LCD screen.

Review;
Check the display with an external monitor. Display checks good, run a continuity check on the Video Cable.
Video Cable checks out OK, go to the Inverter.
Inverter does not cure the problem, the problem is the LCD screen.

BEFORE beginning to disassemble;
Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.

Observe Anti-Static Precautions.
(I would also advise using an ESD wrist strap, and connect it's alligator clip to a good ground source.

Average cost of a decent ESD wrist strap, is around $3 to $6.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
{Electro Static Discharge)

Use a multi-compartment container for the various screws you will remove.
label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.

SOME screws look VERY similar to other screws.
Do Not mix them up.

Try another cable, or check the plug for bent pins. If they are all good, check that the monitor is set for VGA input (if it supports VGA and DVI) as it may be looking for a different input. Then replace the monitor. It's not common, but video processing circuitry can sometimes fail, and yours may have. New 17-inch LCD monitors are quite inexpensive now, so it would probably be more economical to replace this one than to try repairing it.
