Hi, im trying to fix a HP pavilion dv9000, the screen only produces a few vertical coloured lines filling about 1/4 of the screen from the top and some white and black horizontal lines filling the other top 1/4 of the screen. These slowly fade if left on for a while.
I have replaced the main video cable and tested the inverter with another. I have also taken the screen out and plugged it into another laptop which shows that the screen works.
My guess is that it must be the motherboard, or is there any other tests I can attempt?
Thanks for your help
