Re: acer 4736z no power

ktm is right. check coils that is shorted to ground. (determining which section is causing the issue)

post schematic and we will start fixing your mobo kabayan.

Re: acer 4736z no power

Tnx guys but i give up easily. i found one shorted coil and more tantalum caps behind gpu chip. I've tried to removed all of them but still shorted pad. so i assume that it couldn't fix it anymore cos it like liquid spill on it when i first saw the board.

thank you guys...

i think someboddy try to "reflow" chip and fry it, gpu chips ddont fry itself. if u have station u can replace it.
