I should also add that I’ve updated drivers and tried changing the refresh rate of the screen (only supports 59 or 60 hertz)

My Samsung R700 laptop has developed this problem with no obvious cause (haven’t dropped it, spilled water on it). It did have another problem where the screen would flicker and black out (a backlight issue) so I checked connections to inverter and motherboard and it seemed to be resolved. Now, months later, this green pixel issue.
I’ve tried the following with no success:
1. Touching the frame and holding the power button for 10secs
2. Disconnecting and reconnecting cables (to inverter, mobo and screen)
3. Replacing LCD screen (that’s £90 I’m getting back sharpish!)
Does anyone have any other solutions for this? I’ve plugged in a monitor via VGA and it appears normal. Is there any point in replacing the inverter or should I try getting a new screen cable? I’ve not opened up the laptop fully but may as well give it a go before I decide to get a new laptop!

Hi!
I got green flickering pixels on my Toshiba dynabook T550/D8AB (it’s Japanese market product and belongs to Satellite A660 series) a couple of months ago. In the beginning it was just minor flickering “snow” over pictures and video and I thought it was just software problem or some incompatibility since I like to put Western software on Eastern machines (I lived in Japan for a while). Then the green pixeling turned berserk and it was green everywhere where black pixels should be. I connected my laptop to external display of my desktop PC through VGA and it was showing normal screen without greens. So I assumed (thanks to the smart people of the WWW) it was not graphics card. I found Toshiba A660 Series service manual. Opened up the laptop. Very carefully disassembled it until the cable of the back of the screen. Disconnected it. Reconnected it. Assembled it. And it worked! Now I can go back to digital photography!

Thanks to all unselfish, smart people who help others!!

i have a total green screen but after reading some of these threads i moved my screen about and pressed down on it from top & it goes back to normal white screen so its a loose wire to screen saved me a fortune thanks all this is a lap top by the way.

Solution was simple! the DVI connector was coming loose from the monitor, thanks for the support – I just tightened it up, magic, no more little tiny green lights on the screen:)

Thanks – Yvette

Hi,
I am having the same problem, it isn’t the monitor because it displays without the tiny green lights on another PC, win vista 32 bit. It all happened after I downloaded a couple of things from the internet to try out, Syncplicity and Dropbox. I un-installed my video driver, restarted and re-booted, installed GeForce 9400T driver again, but there are still tiny green lights scattered on my HP2159m monitor.

I would like to have a solution if you know of one!

Next Move: I will try installing a different video board if need be, on Windows Server 2008 R2 64-bit – Adobe made me move to 64-bit still trying to overcome all the hurdles that come with a 64-bit op sys. You have to always use the IE Browser 32-bit even though you are in a 64-bit environment, Adobe doesn’t work on the IE Browser 64-bit.

Thanks – Yvette

I’m having the green pixel problem on my computer, but it’s seemingly random, they cut in and out all over the screen like watching an old tv with static, and all true white areas are turned pink. I’m on a brand new 2010 HP, I don’t know the model but i’m running windows 7. Someone please help, i’ve tried playing with all the settings and tried restarting the computer many times.

My compaq presario f700 has the same problem. After searching the internet for solutions and finding none. I have found the problem myself,after many hours of operating on the computer. It is very simple, a broken red wire going up to the lcd display! The bare aluminum ground wire is also breaking and fraying apart at the same location and a green wire was also broke.The red wire was causing the green pixels when broken apart. The location of these wearing wires is underneath the display hing.They then make their way up the back of the screen. So the video wires are obviously experiencing bending and pulling when opening and closing the screen. This explains how having the display at certain angles caused normal operation, by the wire being pushed in contact with the other end and pulled apart. Now just have to get these tiny wires spliced properly somehow and problem solved!!!

I have a very similar problem. AND IT’S IN REVERSE!! Instead of the black pixels turning green, it’s the white pixels!! And the color yellow is also affected.

I have a somewhat similar problem. I have an Asus G5ovt which normally runs fine. However, sometimes random green pixels appear in the areas that should be black. Most the time it appears primarily in text. However, other times it works just fine. I have run it on an external screen and it worked just fine. Sometimes if press on the top of the screen it goes away. Any ideas what could be?
