Re: Panasonic TX-P50STW50 Power Supply no 5V (was clicking)
If the 16v is staying up and the 68Ω got warm, I would say the standby circuit is working. and the primary side and feedback/regulation is all ok.
Adding a load to the 6v line is the only way to check if it is working and able to supply current. About a 15Ω resistor should draw around 500ma, and the circuit should be able to supply that without a problem.
Reconnect ic501, does the vin stay up?
These power supplies were very reliable and the original problem was likely not on the power supply. I would check all the work you have done on it so far.
