My Tv turns on as soon as you plug it than runs with a perfect picture for 1 mint than off & back on by it self & runs for about 5 mints than turns back off & doesn't turn back on until I unplug it!

The inside of your projection tv is dirty. Clean the bulbs but leave no fingerprints or oils on the lamps. Clean the mirror while you are inside it as well for a much brighter picture.

Tv turning on & off by it self

There is a short circuit to its main board. Might be a shorted component, like IC or so. The system control IC detects this short circuit as soon as you switch it ON, it send a command to the main power supply board to shut it down, to prevent further damage. That is happening here. Your TV need a thorough check-up. Will be best to contact any service technician.If you wish to get some details, check the site linked here. Pull up older posts.

My tv turns on and has a picture, but soon will turn off, after a while will come back on but then turn off

hi there, try to check your power cord for any loose wiring or cut portion. If none I suggest you better inspect the power supply and check if there's any deform or bulgy capacitor. You can self repair it by replacing the capacitor by soldering it.
Hope it helps. please rate and vote.good day

I have the same TV, well, nearly, PDP434.

The only part I ever sell for these is the main PSU (power supply).

The TV "checks" it self using a self diagnostic system. As soon as it discovers a problem, it shuts down and blinks an error code on the front LED.

It always seems to be the PSU.

I hope this helps at least a bit.
