Thanks, can you give me a brief summary of the tests you asked me to perform?

KBC sends signal to enable inverter but not LVDS.

I'm going to swap with the KBC of the old board, but I'm not sure if it has problem too. Will report back. Thank you a lot for your assistance.

Swapped it, now I have 3.3V in Pin1 of BIOS, but now the LED lights are off.

I found a netbook motherboard that was working with broken LCD, it was same model KBC, as soon as I plug the power cable, the WLAN light (D537) is on and fan is running nonstop, I can't power it off unless I unplug cable and I have 3.3V in BIOS pins 1,3,7,8.

hi every one, I got before a problem with my laptop, black screen.
In this case the graphic chip (ATI) after some year of working and the hi temperature ; some pins of the BGA soldering slough from the board , because the manufacturer in this period used a bad tin, the same thing happen with the xbox(it use the ATI graphic card).
to resolve this problem; you can make your a graphic card work again by using hot air station to heat the chip until the tin attach again, or use the big means and desolder a chip and remove the old tin and replace with new one (use specific material).
