Our 42" Samsung plazzy stopped working today! First, it would turn on, warm up for a minute, then turn itself off!
Now the power supply has been clicking on and off!
Checked voltages once, 5V was 4.97v and 12 was 11.74.
I have already checked the caps-none look bad.
The supply steps up 120VAC to around 350 volts-that circuit is ok.
The second part of the supply has 2 different smps's, they BOTH don't output any voltage even though the main control board is trying to turn the supply on with the standby +5volts.
Any suggestions?
