Re: when tv turned screen is blank and chirping sound...

A chirping sound usually means that one of the secondary supplies has shorted, most likely the horizontal output transistor. The power supply "chirps", which is the sound it makes when it protects itself from drawing too much current. The set should be serviced by someone with experience in Philips projection TV'.

No Sound, No Picture on Magnavox 51MP392H/17

If you hear a constant clicking or chirping sound get the chirping TV repair kit from

If you have no video - but have audio - its most likey the HVG.

Note: When the video goes out sometimes its hard to tell if you have audio becuase you can't see the screen to change to the correct channel.

No picture, no sound, just chirping noise coming from back

NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...
