Television keeps shuttting off and on green light appears


I have a Sony Grand Wega 55 HDTV, Its 6 years old. Problem is as follows: I press the power button and the TV warms up and goes on for about 30 seconds than shuts off to a no power screen , with the power light flashing green. Than after about 60 seconds the TV comes back on for about another 30 sec and shuts off again. The longer i leave the TV on the longer it stays off when it starts blinking the green light. Can anyone tell me if its the sensor or something else? Is the part I need attainable with the ability to replace it myself.
Look forward to your replies.

I suspect either your lamp is at end of life OR as one projector I worked on the heat sink for the DLP chip was totally occluded with dust causing chip to overheat.

Samsung rear projection tv does not come on


The power supply circuit board has probably gone bad. Repair cost for an in home service call by the major players would be about 450$ plus tax usually with a 90 day guarantee.

Tv comes on and shutts off immediately


Did you change any of the 6.8 ohm 1watt resistors with the ICs? That chassis always blows at least two of the 6.8 ohm resistors often four of the 6.8 ohm. And you cant always tell by looking at the resistors , they have to have one side unsoderd and lifted from circuit. There are 11 of them 3149 - 3160 are the 6.8 ohm resistors that need to be checked.

he was checking to see if the set stayed on with the ICs out if it did the ICs are shorted. Its easier to unplug the convergence yokes and try it but some techs do it differently

Well no, it won't exactly work with out the ICS which is an internal control relay card. He most likely was thinking it was a power distribution problem. My suggestion is to look at the power supply and make sure nothing is bridging any of the circuitry. Just like a computer the on and off button is attached to a set of pins, and just like computer motherboards the controls also exist for a reset. And if anything bridges these pins turning on the unit will just cause it to shut down again. Also look for water damage and heating damage that might have caused problems with the power supply unit.
