Re: tv cycling on and off

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.

Tv cycles on and off

Sounds like bad capacitors in nthe power supply, or maybe a regulator in the power supply. Have a tech take a look at this TV set for you, as there are no user replacable parts available in the TV set. Good Luck

It is likely that the power supply is failing. It tries to start and powers up briefly then shuts down.

The lamp needs to be replaced. It's on the back and easy to do. I replaced mine about 3 months ago and it was about $182.00. Hope this works, I know it's hard to fork out that kind of money at this time but once you do the TV will be as good as new. Take care

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.

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.

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

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.
