Funny you should say that as I asked the same question...I am not sure of where the laptops come from, I simply try to fix them.
HELP!!!! I have 3 laptops that boot but show no video output regardless of the source.
HP Pavilion DV6 . Odd thing is that there is no license information on the back of the laptop to determine the exact model or serial number. I have never seen a laptop like that. The only license information is for windows.
Screen is broke so she was using an external monitor. Turned it on and the monitor didn't react. Tried HDMI and still nothing. I want to replace the screen but now I am having the problem of NO video output at all so I can't access any command screens.
2 I have 2 Toshiba Satellites L505D-S5983 & L655S PSK2LU
L505D-S5983 Did a restore disk for windows 7 and screen miraculously popped up. Updated drivers and cleaned it up. Week later, same problem.. she turned it on and got a blank screen.
L655S PSK2LU Tried the repair disk but got nothing.
I have been told that the video card is integrated into the motherboard but there HAS to be another way around it no?
I hate to think that these are now useless with the amount of money they invested. Both laptops have no warrantees.
Any suggestions or ideas would be greatly appreciated. I have researched online and have tried the taking the battery out and hitting different function keys but to no avail. Thank you.
