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. Sent from my SM-G930T using Tapatalk
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.
Can i try removing the ribbons and see if it power?Sent from my HTC6535LVW using Tapatalk
