i want share this information about this board plhl-t707a. may help someone or some one will help me, cuz i cant find replacement board
this power board it will give <2v beside 5v on the connector p201 pin 3 and 8.
if the connector p201, p202, p402, p401, p205 disconnected then connected the board to the power will take more than 5 min for the standby voltage to reach the 5v (all the caps, doids, fuses, resistors tested good). then i connected the main board and other plugs to the power board the tv will turns on and works fine. so must be something charging slow or needs to get warm for the board to get the right 5v
i unplugged the tv and and give it it 15min plugged it to the wall tv wont turns on, and i got 1.9v beside 5v, i warmed up the u502 ic chip (ice3b1565j) tv turns on from first try, and got strong 5v
i m going to order the this chip and will update if it fix the problem
if someone has any other suggest will be great
thx
