Question about Pioneer SD-533HD5 53" Rear Projection HDTV
Pioneer Model SD-533HD5 Projection TV, working fine one day, the next, when powered on, within 2-3 seconds the green light switched to standby and remains there with no picture. Audio is fine through surround, does not work with any other input setting either.
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.
