Samsung LN46A650 that cycles on and off with no picture. The red light flashes in the lower right hand corner. Still no picture. Have to unplug power supply to turn it off.


Turn it on and let it run for about 30 seconds. If it still doesn't work... unplug it, wait 15 minutes, plug it back in, then try again. If that doesn't work, you might want to contact Samsung to see if it needs repaired or replaced.

The tv has power .the red light is on ,but when it turns on,the green light comes on but then it turns right back off ant the light goes back to red it has a round 1/2" button like plastic plug in...


Tod,
The little plastic button you are referring to is the IR receiver for the Remote. When the TV turns itself off, are there any flashing lights on the front or rear of the unit. Look through the vents in the rear for any flashing lights or try tuning the tv on in a dark room and see if any lights flash and reflect off of walls. If there are flashing lights tell me how many flashes and what color and I will try to look them up in the manual.
