T.V shuts off and power light blinks.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Power Problems


Try leaving it unplugged overnight. It is possible it needs to discharge. If that doesn't work, I'd say you either have a bad switch, or a bad power supply. Hopefully the switch, because that's much easier to fix. Can you bridge the switch connectors with a wire? If it doesn't come on and stay on when you do that, it's a power supply issue (and not nearly as simple to fix).

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

Those lights flashing mean the lamp is the issue. You need to test it with a meter. If the lamp tests ok then it may be the ballast is bad and that is what powers the lamp.

Green Screen, No Sound, Shuts off after 10 seconds


Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.

Sony Grand Wega KDF-60XS955 Picture comes on and then goes off.


You have a bad lamp. Sometimes when the lamp gets old, it doesn't fail and open like they usually do. Instead, the reflector gets cloudy, and instead of reflecting the light, it converts it into heat. As the lamp heats up, it draws more power, eventually to the point where the TV senses it drawing too much power and shuts down, going into a reset cycle. replace the lamp and use an original Sony lamp, as the aftermarket lamps are known trouble makers. Be sure to rate this solution. Thanks!
