Question about Pioneer SD-P50A3-K TV
The TV upon turning it on the green power light briefly lights like 2 seconds then the TV goes into standby red light on. I currently have no cable or antenna hooled to tv.
(3) 4 amp 150 volt fuses (slow burn), and (2) 10 amp 250 volt fuses (ceramic), all replaced. $5.50 worth of fuses DID THE TRICK. Radio Shack has them both. If you can't find a 4 amp 150 volt, 5-6 amp up to 150 volt fuses work just fine!

its the problem of the ics on the main power supply board
Do the IC heat sinks get warm??
If they do not, check fuses F852 - 2AMP, F853 - 1.25AMP, F850 & F851 - ALL 5AMP on the power deflection pcb. THESE ARE NOT GLASS FUSES. They are usually about the size of a 1 watt resistor and either green or orange in color. They are soldered in. The nomenclature is printed on the component side of the board. They are all about centered on the opposite edge of the PCB as the high voltage transformer.
If you have cleaned up the mess you describe you most likely have one of these fuses blown.
if dont have any technical knowledge its advisable to call a technician as it is worth getting it fixed.
