Post by: dex on Dec 24, 2016 at 03:48 AM

Binigay sa akin, kala ko jackpot na..

No power.. check fuses na nakita ko (4 fuses).. ok naman using multimeter.

Any suggestions?

seems to have sorted out the problem. One of the ic in the hdmi pcb assembly got a crack at the top. Further searching for a quick repair online i found out that this model has issues with the said part.

That chip could be shorting the DC supply going to it which in turn disrupts the power on sequence. If you can remove the entire board try mo ipatanggal ang IC via heat gun (sa electronics or CP repair shop), then reinstall the board and try if it powers up.
