Power problem (switches to standby)

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.

    Same Problem! Main power supply on (red light), but normal power (green light) comes on only for 1-2 seconds AFTER I shut down Main...
    Just began happening yesterday 11-3-08.

    I hit a couple buttons on the remote last night and it was almost like I hit them too fast or something (changing the TV settings to go from playing DVD to watching TV) and I heard a "click" and now, my red standby light is on and when I turn it on via the remote, NOTHING happens, when I turn it on at the unit, the green light comes on for a second and goes off.

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.

Try to turn light for 2 seconds the goes to red light off

This model like others near it have soldering problems on the power board.

9 out of 10 times when the power board is removed (follow power cord to it) and resoldered the set again works fine.

Once in a while there will be a blown fuse on that board, bad soldering gets the fuse--very common in these sets.

If you need more input comment here BEFORE you rate my help and I will assist you.

Unplug the TV for maybe 10 minutes, then turn it on. Sometimes these units simply need to recycle. If that doesn't work, you've likely got serious problems.
