hi
Got hp compaq cq 61 - platform : DAOOP6MB6DO Rev : D, lap powers up with white display screen.
Tried on external monitor, always no display.
Debug code : 89 --Bios type: INSYDE_H2O
1*- Could it be a bios issue or GPU fail ?
Heated GPU for test purpose, always white screen.
Thank you for any suggestion.

Unfortunately not yet. Would like first to learn technical terms in russian language to be able to post and reply to posts. Didn't find yet any site on the web for this purpose.

+3V ok
The problem is that there's no display neither on lap-screen nor on external monitor !
У меня было такое из-за дисплея.
и один раз из-за питания дисплея на плате.
- Подключи для проверки 100% рабочий дисплей
I was so because of the display.
and once because the display power board.- Connect to check 100% working display
I already tried with an LCD screen I use for test, always white screen.
Try replace LCD Video Screen Cable

Well, that's what I'm thinking to do tomorrow, as cable is not available now, though cable continuity was tested ok pin by pin.
Also, customer confirmed having used vga port 2 months ago, so it should display at least on external monitor. We will see tomorrow.
Add :
I tried another LCD cable, same problem.
Then tried another LCD, always white display. So problem is neither cable nor LCD.!
