I Have a Laptop that was not working, the screen was completely black. I replaced the inverter with no luck. I installed new graphics drivers from HP and the picture returned - although it is only in the top left of the screen and has ghosting along the bottom. (I have a picture). I have tried using varying drivers, but they all return the problem with the black screen. Im unsure now what the problem is and how to solve it. Please help.

info: Display 15.4-inch ...1280 x 800 resolution Graphics NVIDIA GeForce4 420 Go, AGP 4x, 64-bit graphics accelerator,..32 MB DDR SDRAM if laptop was working earlier,try system restore, check bios settings, try booting in safe mode, check display settings,and monitor, lower screen size temporarly, 6B 69 6C 72 6F 79 20 77 61 73 20 68 65 72 65

thanks for your reply. it has had a re-install of xp pro. - but wasn't working under the old os the laptop wasn't working when i got it. I have tried safe mode, various drivers, bios, and settings - unfotunately to no avvail. its running a geforce4 440 go 64m if that makes any difference. I have noticed that there are no widescreen resolutions available in any of the settings menus. the machine also doesn't display any picture until windows boots, i have to connect an external monitor to view the bios! Thanks again for your help so far

My (unbranded) laptop has a hotkey combination to switch the display between monitors. I haven't used this function, but I believe it was a combination of Fn + one of the F keys (sorry, I can't remember which one). The fact that you can see the bios when an external monitor is attached would seem to indicate that the wrong monitor (external) is set as the default monitor. Try Fn + each of the F keys. Please let us know if you found someone's advice to be helpful.

could be that the montior itself is bad. best of luck Frank :
