When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?


Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet.

5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

Sony lcd projection tv kf50xbr800 shuts down and


Hey there, from what you are telling me I think the problem is coming from your Power Supply board it sounds like it could be two things

one: the board might have gone bad and its not sending the corresponding voltage to your components and that is why it keeps turning off

example: works ok for a while then gets weak truns off and then gathers enough turn back on

two: the power supply could be over heating and it has a sencor when it gets to hot to turn off this is very rear though

please rate this solution !!!
