TV goes to green, sound stays on a few seconds then TV shuts off.

Sounds like you have a bad picture tube. More than likely the CRT could be shorted, which would cause the set to shut down.
My first advise would be to power up the set with an isolation transformer with the voltage about 60% approx. 72 Volts AC, and monitor what happens when you increase the voltage slowly.
If the set remains on at 60 -70 %, then when increased to 90 - 100% it shuts down, you have something drawing too much current ( which could be the CRT )

Sony TV shuts off automatically

1.Check first if the shutdown of your tv follows a certain period of time. Example after using it within 12 hours it automatically shut down. If so the the matter is only on settings of your tv.
2.But if your tv shut down at an irregular time the problem is in your board. In this case if your tv still work but still shutting down automatically its better not to use it so that their will be broader damage.
3.The most common defect on this case is loss contact of components due heat and mechanical undergone during the usage of the tv. If you know how to resolder board, try to resolder the components specially those who are showing loss contact. You can recognize it because a good solder one has shinny and no round like on the soldered surface.Try also to resolder important parts such as IC's and transistors. note : a good resolder needs to be done in order to avoid problems and damage.
4.Another possible cause is the tack switch for channels,menu,power and etc. You can remedy it by spraying it a contact cleaner.
5.If the problem still going even after the procedure its better to bring it on reliable and trusted service center.

Rainbow screen then powers off

The degausser cricuit may be the fault. The degausser coil may be staying on, and thus forces a shut-down. It is also possible to have a power supply fault that can cause a similair effect.

The set will need shop service.

Samsung 56" shuts off after 5 or 10 seconds see a checker board image before shutoff

When the set shuts down you need to see what lights are blinking. For example: Timer/ Temp/ lamp on the front panel. You should also count the number of times they blink and the sequence. Most DLP`s give an error code alerting the technician to check the balast, lamp, or fan etc. for malfunctions. Unfortunately I can not tell you exactly what is wrong given the current information. Howrver, the last Samsung I repaired for shutting down had a bad light engine.

TV doesn't turn on

When the set is turned on, the computer senses that something is wrong and immediately shuts the set back off. The standby LED will then blink a code, a certain number of blinks, to indicate exactly why the set was shut down. It is possible that your audio output IC is shorted, as this would make a pop or strange noises in the speaker just before the set shuts down, which it does to protect your speakers from burning up. The set should be looked at by a qualified tech familiar with Sony TV's.
