Question about Computers & Internet

My eMachines D620 laptop has a series of white lines at the bottom of the screen, they start really bad but reduce as it warm up. They are not software related as they do not appear on a screen save/grab.

This could be a possible hardware failure. Try to contact your manufacturer and hope you still have an active warranty for this.

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.

Will a replacement screen for an acer aspire part #5733-6607 work in an emachines e525 series


https://www.laptopscreen.com/English/model/Acer/ASPIRE%205733-6607/

http://www.lcdscreen.com/eMachinesModel_eMachines_E525.htm

First of all the eMachines E525 has to use LED backlighting.
Does it?

If so there is one requirement that is crossed off.

No? Then the answer is No.

Next, you really need to look at the manufacturer ID info on the back of the Acer's LCD screen, and the same info on the back of the eMachines LCD screen, to be SURE.

Example,

http://www.insidemylaptop.com/replace-screen-on-acer-aspire-4830-series-laptop/

Scroll down to the bottom of the page, look at the last photo.
THAT, manufacturer information.

'Armed' with the Acer's LCD screen manufacturer info, then check to see what all laptops it will work on.
And/or if it works on the E525.

THIS, is the theory.............

The LCD screen of course, isn't manufactured by Acer.
Neither is the eMachines LCD screen.

(In fact the Acer laptop isn't made by them.
Neither is the eMachines.
One of three main companies made it for them.
Quanta Computer, Compal Electronics, or Wistron Corporation)

LG, Hitachi, Sharp, NEC, Chi-Mei, HannStar, Philips, and Samsung; are just a few LCD screen manufacturers for laptops.

If you give me the Acer LCD screen manufacturer into, and the eMachines LCD screen manufacturer into, let me see if I can find out.

Do you have the eMachines recovery disc? If so, then you need to enter the bios of the laptop by pressing a speciffic key at the start of the boot process. It should tell you what key to press in the POST. Most likely across the bottom of the screen somewhere. The F2 and F10 keys are popular as well as the Delete key. Once you get into the BIOS, Locate the menu containing the boot sequence. Make sure to set the CD/DVD drive as the first boot device. Save the changes and exit the BIOS. Put the Recovery or Windows CD/DVD in the drive and follow the on-screen instructions.

Why is my Dell Latitude D620 laptop screen turning white?


You'll have to live with it. It's taken damage, it's not repairable, it's only replaceable. My Latitude screen was replaced after only 2 1/2 years.

Cannot get the Projector to see my emachines D620 Laptop screen. Press FN+F^ my computer screen goes dark but nothing shows at the projector tested the projector worked fine with other laptop


To check if the external video port on the laptop by connecting an external monitor to the laptop and see if it works. If it does work then the video port is OK and the only thing I can think of is :-
What is the highest resolution that the projector can display?
Is the video resolution on the laptop set higher than the projector's maximum resolution, if so reduce the screen resolution on the laptop.
