Hello! I have a P652ui-b2, and it was working great for about a year. Then just randomly one day it would not turn on or work at all. I have already replaced the cord, and the power supply. Is it possible that it could be one of the other boards causing it to receive no power at all? I ordered a main board. A Led driver board, and I believe a TC?board. Any help would be great, I already tried to hard reset and stuff like that as well. The logo will not even light up.
