Tv randomly turns off. Not sure if it is overheating or if something is broken.

It sounds as if you are having problems with the AC Power reaching the television. Please verify the cord is firmly seated the tv's ac inlet
Also check the wall outlet (and power strip) by plugging in a lamp into it and see if it flickers when the tv shuts off.
Good Luck!

Hi, the tv comes on ok for about 15 seconds then goes black and all 3 lamps start blinking. when I try to shut it off it repeats the cycle. I have to unplug it to shut it off

This could be caused by lots of things.

Possible causes that come to mind are.

1. TV is over heating -

2. Power cord not securely plugged in the wall outlet.

3.lamp door cover, which could trigger the auto-shutdown switch - you can fix this on your self by correctly resetting the door cover witch.

4.The power board is Malfunctioning

You may want a local company come out and take a look because it's difficult to pinpoint the cause without looking at it. You can find a local shop google tv repair in google maps, or call 800-SAMSUNG for an authorized technician.

TV not staying on

If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!
