Laptop shows a blank white screen even with a new LCD
I bought an old Toshiba Satelite which arrived with a smashed screen, when switched on showed a blank white screen, changed screen, still lights up white. Changed the screen lead, still lights to a blank white screen. External VGA works fine. Whats left motherboard perhaps?. Am I right in thinking that it cannot be the inverter as the screen lights up.
You are correct. If the screen lights up (even without any image), the inverter board works properly.
You’ve replaced the LCD screen with video cable but still experience the same problem, so it must be related to the video card. Most likely the video card is integrated into the motherboard, so it’s the motherboard problem.
This article explains how to troubleshoot laptops with white screens.

I have an HP DV5000 and I am having a screen issue. It is about a year or so out of warranty and recently the screen has been going blank. I found that when I had the laptop plugged in the screen worked fine. When the laptop ran on battery it would go blank. I figured that it must be the battery and waited to fix it. The other night the screen went blank while it was plugged in. I also noticed that the plastic frame around the screen was beginning to melt/deform in the lower right hand side. I immediately turned the computer off. After doing some research it looks like I may have a bad inverter. Do you feel the same? The screen still works because you can see it slightly, it is just really dark. Any thought would be greatly appreciated.

I cant get any external monitors or tv’s to work using my yellow line out port on the back of my Toshiba Satellite. I read all troubleshooting info and help messages i could find and they all said i had it set up correctly… i can get fuzz to go through when i click on certain things so i know its feeding… If you can be any kind of help it would be greatly appreciated…
Thanks,

I have a 17″ laptop hp pavilion, within the last 4-5 months, my screen displays gray with some lines when I start it up or revive it from hibernate mode, sometimes it will pop in on it’s own other times I have to play with the angle of the monitor before I can get an image. What could the problem be? I’m afraid it will blank out completely.

Same kind of problem with my Toshiba Satellite A100-110:
-Replaced screen & video cable – it didn’t help. All connections & pins on motherboard & screen seem to be fine. Re-seated them all twice. Besides screen cable output on the motherboard there are other ports, like USB & internet placed on same board and they’re working.
-Screen lights up, but with no image.
-External monitor works fine.
-Windows & BIOS detect both screen – external & laptop one. Can change all the settings for laptop screen, but it doesnt help.
-Videocard is Ge-Force 7600GO. It was replaced under warranty after a month since purchasing the laptop.
What could possibly the problem??? I have suspicions only on videocard now.

I have a screen problem. Today while I was watching pictures, I clicked on ATI logo on taskbar. And when I clicked the screen turned black and white. I restarted computer but it didn’t help. I restored defaults on ati properties but it didn’t help. I have Samsung R20 laptop with ATI Radeon Xpress 1250 graphics card. How can I get the colors back?
