Tv wont power up

I have an RCA P46734BA projection tv. My problem is this. When I push the power button the tv wants to turn on but it comes on then goes off right away. I took the back off and all I see is alot of wires and plenty of dust to go along with it. I have checked most of the capacitors and none are blown or swelled. The resistors look good also. What should I look for?

    Thank you for responding. When I power up the tv, the power button light comes but then shuts off. It does that 3 times then nothing.

It is most likely the capacitors in the power supply

    Possibly the projection bulb but you would probably get a flashing warning light on front of tv. The ballast also tends to go in these tv but is hard to test without ohm meter and schematic.

    Than your power supply needs to be replaced unless you can replace the capacitors inside the power supply

Different possibilities:
1. Bad hv circuit (flyback)
2. Bad connections on flyback & the little fuse next to it
3. Bad fuse near tuner
4. Bad picture tube
This tv is known to have any of these problems.

Wont turn on


Check the solder connections on the flyback and also right next to the flyback there is a small white coil with copper wrapped around it that will sometimes arch causing the solder to need re-soldering
