My laptop has green pixels where black pixels should be
My laptop has green pixels where black pixels should be, so in other words when the Windows XP splash screen comes up during bootup the screen is completely green except for the logo of course. Every “true black” pixel is green colored and the problem is there when Windows is running too. I can see they are not dead pixels because all the pixels do it when a black pixel should be there. I had a friend who is a Toshiba certified technician take a look at it and he said it looks like coffee was spilled on it but the LCD is fine so it seems to be something with the onboard video. I am great with making and repairing desktops, but not laptops, though I could if I needed to. Can anyone suggest anything besides getting a new laptop or a new motherboard. The MB sounds better than a whole new laptop.
One other thing I should add is that when I bought it on eBay it was sold because of the little green pixels but it was reported as showing up here and there, when I actually received the laptop the problem was completely gone. Then I sent it to UPS because i filed a claim since they damaged the power supply and also the CD-ROM and when they shipped it back the green pixels then showed up and much worse. Nothing helps, twisting the LCD , banging it a bit, nothing at all helps it. So its weird because after I bought it from eBay UPS delivered it and the so-called problem was non-existant, then I sent it back to UPS, then they shipped it back and the problem was there. Can anyone help please??
There is no simple solution for this problem. If the coffee went down to the motherboard, I think you’ll have to replace it.
By the way, what if you start the laptop with an external monitor? Do get the same bad video on the external screen (indicates a problem with onboard video) or the external screen works fine? If the external monitor displays normal video, may by you just have a bad video cable and there is nothing wrong with the motherboard? Test the external video before you make any conclusions.

Ken,
I guess you’ll have to check connection between the video cable and LCD screen.

Green pixels where it should be black. I applied pressure to the back of the lcd while the laptop was on. I believe where I applied pressure was where the lcd connects to the MB output
The problem is resolved by applying pressure in this way, but i’ll eventually have to take it apart for a better look.

I had the same problem and have investigated quite thoroughly: The LCD screen cable is wrapped in a metal mesh from the motherboard up to the back of the LCD screen, probably to protect from interference. Behind the LCD screen (fairly close to the bottom), there is another metal mesh piece glued onto the metal foil sheet behind the whole screen. This connection seems to be important. After long time, or vibrations from travel, the small metal mesh piece gets compressed a little bit, and the connection might be lost. Then the green pixels (instead of true black) appear. This is why wiggling the LCD cable will sometimes work to eliminate the problem. Also some people have changed the LCD inverter, or repeatedly plugged and unplugged the LCD cable which amounts to a wiggling of the cable and thus fixed the problem (even though is was neither a problem with the plug nor the inverter. The easiest thing is to wiggle the LCD cable a little bit where it goes up behind the LCD screen. A more thorough fix is to unscrew the 4 screws holding the screen in the frame, look behind it, and gently reshape the (compressed) little metal mesh piece, so that it sticks outward a little bit more, and the connection to the cable mesh wrap is ensured.

Even we had the problem with our Lenovo 3000 N100 series. We downloaded the latest drivers from Lenovo site and everything started working fine.
Thought of sharing this information that will be helpful for others.
Thanks

After 15 months of being annoyed by green pixels on my Acer Aspire 5610, all it took was 2 minutes of work by removing the long panel above the keyboard and just putting a little pressure with my finger onto where the LCD screen cable goes into the white connector.
I could see on the screen how the green turned back into black while wiggling around a little.

Hey all, just wanted to add a small twist to the same question. My Toshiba P205-6267 has res pixelation in the black. during startup and with any pictures where black color is appropriate. Additionally, I have changed out the LCD cable (no change) and the LCD itself (no change) and as many others pluged onto an external monitor, it works fine. I’m at my last legs with this issue, I think it’s time to put a British 303 round into it. Please help.

Mine was loose LCD connector on Acer Aspire 5630 laptop GeForce go 7300.
I disconnected the cable, plugged it back in, turned the laptop on. Green pixels were still there.
While it was booting i applied pressure to the connector and the green disappeared.
No longer a problem! Thanks everyone for your input!

I have the same problem with an Asus A8J Running Ubuntu Linux. The green is not there all the time. It comes and goes with no apparent pattern. Sometimes it’s just pure black (RGB 0,0,0) that turns into green, but sometimes it’s other blacks (a small range around pure black like RGB 5,0,0 or RGB 0,5,0) that also go green. I hope someone can find a good solution to this problem.

I’m having this issue not with a laptop, but with my new Lenovo L220X LCD monitor. Green where black should be, and other discolorations. It happened when I pulled it out of the box it was shipped in, so I’m guessing it was dropped or something in transit.
Unfortunately, I seem to lack any way to take it apart and “touch the metal” like is being described here w/ laptop LCDs. I just wanted to post this as a problem because it was hard to find this issue being reported anywhere on google, especially for LCD monitors vs laptops.

I just checked the cable ends to the LCD screen and they all seemed to be tight. I pressed them in again anyways. I put everything back together, turned it on and the green was gone. It was a Toshiba A25-S207. Thanks for everything everyone wrote.

I know this is late…but here goes:
My friend has this same problem on a Dell laptop running Win Vista. Just appeared out of nowhere on random areas that should be black…but are now green. I changed the brightness which alleviated the problem when looking at pictures, etc but not with the green pixels around the border of the screen or when the screen flashes from changing resolutions. He also gets an igfxcfg error which I believe to be a key to the problem. Since the problem just appeared and most of the green can be eliminated by changing the brightness, I hesitate to just yet call it a graphics card or lcd error. However, sometimes the card/cable that hooks up to the actual screen can go bad, and not the LCD screen itself (had some experience with laptops from last job) which may result in odd screen behavior. I am having my friend try it on another monitor..so standby for results.

Its just the cable, where it goes through the LCD screen. The cable is broken. (I fixed my friends)

I also got the problem whit my Compaq presario v2000. I’m thinking it all started when the laptop fell of a table. THe hd broke, and the screen outer plastic cracked. The repair guy told me i was lucky the screen didn’t get damaged. so the whole pc got fine after i replaced the hd. A few months later some pixels just went dark, like if they were not receiving electricity, but after rubbing the screen they went on again. two months later a whole horizontal line of pixels just didn’t work,no matter what I do they didn’t worked again. I managed to used it without that line, but yesterday suddenly after opening my laptop, all the black pxls went green. First they only got green after opening the screen wider than 100 degrees, so it was kinda fine since i dont open it that much. but today, the range i have to open it so i dont get the pxls is just about 30 deg.I rally need help, i luv my laptop and i dont want to lose it.
Thx

same problem with my old Ibm thinkpad… I replaced the screen in it and it still had the same messed up green screen when I turned it back on. a couple weeks ago at my grandparents house it had the exact same problem so I opened it up and laid it screen down out in the sun for a couple minutes and brought it back in. it still didnt work but my cousin randomly reached up and gave it a light tap on the lower right side of the screen and instantly fixed it… it was pretty funny actually

I have a similar problem but my is a 46”Vizio LCD TV.green pixels where black pixels should be on the LCD screen Can u please advise me on how to solve this problem since it’s a bit different. WHICH METAL SHOULD I TOUCH, SHOULD THE POWER BE ON, ANYTHING PLEASE?
June 27th, 2008 at 2:18 pm
I had the same problem(blue pixels instead of black) with my laptop…I increased the brightness of the screen through the display settings…..I can now view the images and videos better though the boot screen remains green..

So more than a year later, I forgot to report that in my case, the connections were a bit loose. But everything has been working great sense they’ve been tightened up.

Do you have to press the power button until the lights are displayed?

I’ve had this problem intermittently with my Toshiba M70 Sattelite ever since I recieved it back from service on an unrelated matter.
I’m convinced it’s a loose cable connection because I just “resolved” the latest instance of this problem by strategically smacking my laptop near the base of the LCD.
Of course, this problem has appeared and dissapeard without any discernable pattern for about the last month. Sometimes a well placed jolt corrects it, sometimes it seems to correct itself. The severity of the problem is not constant.
I guess the only problem I have is that I don’t want to send it away for two weeks so they can open it and plug the cord back in that they (I’m assuming) didn’t plug in correctly when they had it open to repair the motherboard. No matter how hard you try, you can’t convince the in-store techs to fix a warrantied problem, they always send it away.

Oh yeah, sorry, I forgot. My laptop is a Toshiba A25 S207.

Hi there, Thanks for all the posts. I had the green pixel problem after disassemblying my laptop to repair a touchpad. During disassembly, I broke the white plastic LCD harness socket end which plugs into the motherboard. I tried to super glue it back together, and then when booting up, GREEN! I ordered a new cable from EBay for 17 bucks and replaced the broken cable. Well, boot up and still GREEN. I found this site and read the posts.
First, I touched the exposed metal of the back of the laptop, with the cover removed and pressed the power button for 10 seconds… still GREEN…
I thought maybe some glue was still on the gold contacts of the female LCD plug on the motherboard from the mail white plastic plug I had tried to repair, so I plugged and un-plugged it maybe 10 times.
Hit power and BADDA BOOM! All clear. So, I am not sure what exactly was causing it, static or bad connection or both, but thanks for the posts, it gave me confidence I could manage to fix my machine.

My iMac displays solid green where it should be black. This is the new iMac, hardly a month by the way was also delivered by UPS from apple online store. Does UPS not know how to handle PCs, or what? I am not a wiz so I have booked mine to be sent to nearest Apple repair agent (not with UPS) coz my printer cam with them as well and had to be replaced. Purchasing these 2 items has been a pain. But I spoke to a certified apple engineer and he told me that the problem is fixable. I got the impression that it is only something loose in the iMac. Hopefully it will be fixed. (Thought i;d contribute since iMac is technically a large tablet like laptop)

Hi,
I’m currently using a Toshiba Satellite P205-S6267 model laptop. Starting yesterday, I began experiencing the green pixel problem myself. I’ve come to the conclusion that it IS a loose connection. I’m not all that computer saavy, so I’m not sure if there’s a way I can get to this cable myself to fix this. Could someone elaborate how I would do that? Or would it be a better call for me to take it to Geek Squad at Best Buy or something of the sort?

I have the similar problem with my Acer Aspire 5630 laptop GeForce go 7300. In any image file, or text file in which the color is black, some green spots or lines are coming out on those balck color places. Though it is not fully green, some places of black colors are becoming green.
Any suggestions?

Hi!
I am having the same problem with my Acer Travelmate 2424 laptop. The funny thing is that it temporarily disappears when I bend the screen from the top, or if the screen color becomes suddenly much darker. The problem disappeared for a couple of months and now seems to have reappeared. Any suggestions?
Thanks,

Great post everyone.
I have Toshiba Qosmio g30(no serious probs since purchase) that suddenly developed the green screen problem.The xp start up screen is green & black/dark grey pixels are also green. There is also some red pixel distortion in scroll bars and menu boxes.
I was using it fine today then i half closed the screen and left it to go on standby or hibernate. Anyway, when i flicked mouse to turn it back on, the green pixels were all over the desktop. PLEASE bear with me on my steps because i really don’t think it is a fatal hardware fault and don’t want to dismantle yet!

Issue Solved:
Thanks to all who helped by posting their suggestions and their experiences. I have gotten the laptop to no longer have the green screen issue, I believe it was static electricity or it was adjusting the video cable on the LCD side of the cable, thanks again to all and hope this helps someone in the future.
