Tv shuts off, every muinute- 5 minutes. it will cut back on but repeat cut off

Set may have like a car with a check engine light have detected something and shut down as protection-----monitor it and if it gets worse or repeats consider having a shop examine it.

I would suspect issue is or was on power supply board.

from how long you have this problem? and what made it start?
do u remember the cause?

hello
1- you check thermostat .
2-maybe temp your house is below 26c.
3-you check fan condenser and evaporator .
4-maybe cut off low pressure system.

The power supply board have problems,not giving the wright voltages to the tv anymore.That why,the tv shutting down 5 to 15 minutes.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Check that you have not got an auto power off setting on. Check that the aerial connections are good. That the signal is strong from the stations it is picking up. Weak signals can cause the box to shut down.
It the box is very hot when it shuts down, you might have a fault on it.

There maybe some loose components on the circuit and that needs resoldering. Bring it to the repair shop to done.

weak power supply

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

Replace the lamp as that is most likely the suspect
