Re: monitor problem

I am seeing many people have these type of problem. Why did it happen? I have a couple of vertical line on my LCD. If I applied a little pressure to flex or twist in. It does go away. What does it mean? What is the cause? Is it repairable?

Re: monitor problem

Sounds like a bad lcd.... any time you get vertical or horizontal lines, usually, the lcd needs to be replaced.

If you flex the screen a little, does it change? Don't use alot of force, just grab the laptop lid from both side and tweak it a little to see if the lines change or go away.

What make and model is 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
B) Video Cable
C) Screen Inverter
D) LCD screen

LOT of reading ahead.

1) Graphics chipset:

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

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

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,

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),

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,

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.

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, ]

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,

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

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

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

When i starts my laptop, i can see black screen. in bright light, i can read littlebit but now clearly. can you please tel me whats wrong? what i need to do?

If I had your laptop model I could point you to the exact part. It is a bad LCD inverter. It is a small tube shaped circuit board located under the LCD screen behind the screen bezel. One end connects to the LCD data cable, and the other end has a 2 pin connector that goes to the LCD backlight bulb. The part is usually about $10-15 and is relatively easy to replace yourself. Remove the screws on the bottom of the screen bezel and carefully pull the bezel out toward you. You will see the inverter there. Unplug both ends, replace with the new one and re-assemble. cheifhoho.jpg

Broken lcd, how can we go about it.

Call HP to determine if the unit is still in-warranty, and they will be replacing it. Otherwise, you may have to upgrade it through their Out-of-Warrranty programs.

5610 lcd screen goes to a crazy pattern at times. It does not happen on a lcd monitor connected to the monitor port.

Patterns and lines are indicative of an impending screen failure or a loosening of the flat data cable on the back of the display.

When I turn on Dell Inspiration 1525 laptop. after 2 minute it appear blue screen error and then restart the system.

As soon as you see your "wallpaper" on the Windows desktop, click Start.
Point to My Computer.
Click with the SECOND (usually the RIGHT) mouse-button on My Computer.
Click Properties.
Click Advanced.
Below Startup and Recover, click Settings.
Click to remove Automatically Restart.
Click OK.

Now, the next time that you see the "Blue Screen Of Death", what message _stays_ on the screen? Write it down. On another computer, do a Google-search for that string, and read what others have done when they have gotten the same error-message.

Get an old monitor CRT or LCD. Connect this to the back of your laptop to the appropriate connection. Turn on this monitor and your laptop. Now on your laptops keyboard are some blue highlighted keys called function keys. Press and hold the one marked "Fn" and then press the F7 key (on my Sony - yours may be different but the key with a small blue rectangle with LCD inside a foward slash to what looks like an oval with square sides) this is the external monitor key. If the external monitor comes on with the laptops screen information then your mercury lamp in the laptops screen has died. Then a reputable repairman can replace your screen and lamp for $200. - $300. If nothing appears on the screen then most likely the video chip in your laptop has died. Replacing this will require a new motherboard for the laptop. You should contact Sony about price and any extended warranties they may have,

Blank Screen


If you can hear your windows loading but no display, try plug-in an external Monitory on your Laptop. If you can see the display on the screen with this monitor then maybe your LCD or Inverter is broken, or try turning on/off the switch for External Monitor and LCD Display on your keyboard. Usually by holding the "FN" key on your keyboard and look for the LCD/VGA icon on your keys then press it.
