someone to help me, I have a panasonic tv model TC-P42C2X, with a SanKen PSC10312K M source, I only have the 5 volts of stambay at the source, at the source, nothing more, but the stambay led does not turn on, the tv is dead, the activation of the source relay is not heard My question is how can I discard the source? Is there any way to pluck the source? I know the defect is between the main board and the source, but how to discard one or the other? At first glance you don't see anything burned, I have reviewed almost all the components of the source, except for the integrated ones and everything is fine there is only the 5 volt voltage of stambay at the source, but the teelvison stambay led does not turn on I need help greetings ernesto

you will have to look at what two connectors the bridges have to do, because the truth is that I don't know this board and it can be a false load and then unlike the led ... two bridges have to be made between normally-connected ps-on and ground pins and on the other connector with vson and a 47k resistor and the 5.5v pin

Good afternoon, panasonic plasma when not activating the relex is because of the 3.3v that is generated back to the source and therefore does not activate the relay just be connected to the AC line, therefore and by experience the pcb main board It's bad and that's the evil of that model.

And what about the 15 volts of stambay that the source must give and does not give them, coincidentally those 3.3 volt sources on the main pc, feed on the 15 volts of stambay ????

hello sir ... then activate the source outside the tv, verify that this ... has all its voltages and once verify that they are present ... then you will have to look at the diagram of that main to continue Have this maybe if it suits you: https://yoreparo.com/tv/televisores/tubo/preguntas/1413438/problemas-con-fuente-conmutada

How's that going? Have you got that manual yet? there will be another question about the manual and I fail it in itself, usually it is capacitors that have to be changed if they are ok ... you look at regulators and diodes ... that's the first steps
