[mcgaiver]

Hi, i've this notebook that works perfectly to except the video display. On the keyboard it has been versed any orange juice. When i disassembly i saw the oxide near the connector of the display. It has been cleared with alcool and soft brush. Now i want to repair the component that it is fired. Could you help me please?

If i connect the video display on the ext port i see the video correctly. I think it is the electronic circuit that permit to the CCFL inverter to work. The video show on display but the retroillumination not. I have tested the inverter also.

Some minutes for post the photo of the part of motherboard.

For no backlight, check voltage on pins 37, 38 and 39 of CN1 (page 17).

See here for boardview/schematics:
