My PIONEER PDP-503HDE 50 INCH PLASMA screen won't power up

I became the owner of this TV when I bought the house so I guess it is about 4 years old. Most of the time the Plasma will fire up using the remote control but on some occassions I have to hit the standby/on button to make ot work. Today however this doesn't work and the MAIN POWER BUTTON briefly goes green before returning to flashing red. I am guessing some part or other has failed ? any ideas ?

    Sounds like what has just happened to mine. It momentarally switches on then appears to revert back to standby but the led on the screen flashes red in 5 quick successions. None of the usual troubleshooting advice works. Hmmmmm

    Mine is only one year old and it keeps reverting back to standby after a short period. Anything I can do?

Your set is overheating. It has a built-in temperature sensor which switches it off.

You guessed right you got a problem with the projector, I always point my finger to Power suppy problems on these sets for about any other problem would mean throw-away or too expensize to fix. good luck

play station start in 800x600 and then boot to your recommended settings the tv picks up the signal from the ps3 to change to these settings if the signal is not being changed then it could be a problem with the cable and usually pulling it out while its on and then back in again sorts this out.

I seem to have lost audio from all inputs, any ideas (have checked mute etc)

Televisions receive sound through the tuner then amplify using an audio chip.  Both are prone to cold solder joints  when they are under a year old over aging solder joints when over 10 years old.  Your audio chip may have failed.  Hopefully your tv is still under warranty.
