Re: TV comes on and shuts off after about 10 secounds

This particular model has a history of this problem.

This sounds like a safety feature built into the television. It may be trying to protect itself from an unsafe electrical source. The more expensive the equipment, the more sophisticated the power supply that converts the power from your outlet into your television. There could have been a lightning strike that has disabled the tv. Or it could be a faulty outlet.
Before called for a technician, I recommend plugging the television into a different outlet. use a good quality extension cord if necessary. You may find that your outlet is not polarized correctly.

Picture freezes, sound continues for 5-10 seconds. tv shuts off and comes back on after 5-10 seconds. problems reoccurs with increasing frequency.

In these cases you might be able to see a picture by shining a bright light right next to the screen front. Do not put the light there for very long or you will end up with a permanent bright spot burt onto the screen. I have discovered that applying light pressure with a 3/8" thick rubber or plastic shim corrects a panel inverter/driver board/card solder problem with many flat panel TVs. (Removing the TV back is required, try light pressure against the inverter board while wearing rubber gloves and tv is then powered on.)

You have a power supply problem. Within about 32 seconds the picture drops out because the backlite transformers shutdown. Yoy will have to find a new power supply or have some one fix yours.

Tv shuts off after 10-20 minutes

its not the problem with ur electron gun tube or with any picture ic or sound ic. Every t.v. is microcontoller switched machine.
any damage to microcontroller ic that controls the switching will lead to this kind of problem.
0.01% chance of residue EHT voltage would have affected the microcontroller.
