Phillip you have a problem in the main power supply or in the High voltage shutdown circuit. Now the longer you wait to have this fixed the more its gonna cost ya Unless your a tech then get a schematic and measure the voltage on the hv shutdown pin on the video junglke ic when the set shuts down If the voltage at the time of the shutdown sodent spike up then you know your problem is in the power supply. Good luck

Shuts off and on while trying to watch, the power light flashes 30 times when off then the tv comes back on again


Power supply trouble. The TV keeps trying to start then operates for 2 seconds and shuts down. The cycle keeps repeating until eventually the TV will not start at all.

Hi,
It is clear symptom that lamp is near to end of its wroking life and tv needs lamp replacement.
Please replace lamp in tv to get it back in business. Lamp replacement procedure would be written in user manual and its easy.
Please buy Sony original lamp for good picture.
Let me know if you have additional question.
Thanks.

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

I turn the tv on the green light comes on then the tv shuts off. after that a red light starts flashing.


the red light that flashes is it in the screen or on the power button area. it sounds like your image circuit is out of specifications something is causing a surge in your voltages could be a bad resistor or bad I.C.

Flashin power light - wont come on


The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
