I am working on a Sceptre X42BV-FullHD that is not creating secondary voltages on the power supply.(FSP270-4M02 or 3BS0134112GP) I have ordered two power supplies from ebay and both are having the same problem. I am getting the 5v standby voltage and approx. 2 volts at p-on when the power button is pressed, but no 5v or 24v source.(24 measures .57)(12 volts not used)
I am testing this board in the tv with nothing connected to it, but the power cord. Jumpering 5v stby to p-on using resistor to supply around 3v to p-on line. Also tried using external dc supply for p-on. no secondary voltages.
I have two questions. First: Am I testing this board incorrectly? Second: I dont see a relay on this board, so are the 24v and 5v secondaries supposed to be on all the time?
