Re: 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

The picture will go black and the sound will go out. At the same time, the green power inicator will flash. Then the picture and sound will come back on for several seconds and then it will go out again....

My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions:
Please turn ON the TV. While holding down the RESET button on the Remote control, press the POWER button on the TV. The TV will turn itself OFF, then back ON again. Release the RESET button.The TV will go thru the initial setup, and should work normal.

When turning on the TV the green light on the front does not come on. You hear a click and then about ten seconds later you hear another click but the tv never comes on.

What light do you get, green blinking, red blinking, yellow steady light or yellow blinking light. The led lights will tell what is wrong with your tv.

Lamp light turns red

Yes this is the signal for a bad lamp. Other things can cause this. 1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.

Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.

If you here the color wheel spin up and no ticking sound, the Ballast is bad.

The ballast part no. 939P978010

The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.

No picture, no sound, power light steady green

First: Check the power outlet. Check it with a good lamp so you know you are getting power to the set.
Secondly: Check the power cord. Wiggle it around the molded ends to make sure it is not open inside the molded portion of the plugs.

Thirdly: If you know for sure the set is getting power and still no indication at all (you should be getting some little light on the front panel; standby indication) then there may be a fuse on the back panel or just inside the back cover (you will have to remove it; after unplugging the power cord) that needs replaced.

Fourthly: After all these checks if you are getting nothing, you may have some failure inside that is very serious. Normally we do not recommend serious repairs to a set over 4 years of age. This is because the set is likely to develop some other problem soon after the repair is made; further, the repairs are getting more expensive day by day while the price of new sets is coming down dramatically. Lastly, the new sets have better picture, longer lasting circuits and better features.

Hope this is a good solution for you.

thanks for your questions.
