This just started happening in the last couple of weeks. You are watching a program and it shuts off for about 5 seconds and then comes back on. It will do this throughout a program staying on for different lengths of time. Eventually, TV shuts off and we are unable to turn it back on. After waiting about 3-5 minutes, we are able to turn it back on. Any guidance?

Re: TV turns on and off constantly.
This is the heat detection circuit that detects to much heat in the set , cleaning the inside of the set of lint , dust , ect may stop it or it has just been dirty to long and that circuit will now have to be replaced

if it turns off and the timer light starts blinking you have a bad dm module, very expensive, it the light doesn't flash you have either bad front switches or something on the signal board, you can remove the speaker grill and disconnect both plugs and use your remote, this will disconnect the switches. if it still shuts off, you need baord repair, may be a bad solder connections, may be a chip/board needing replaced, you need a repairman and alot of money at that point.
One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.
Try a power drain and monitor if the TV continues to do this or not:
1. Unplug the product's power cable so the device is not grounded to the house.
2. Press and HOLD the product's own power button for 1 minute to drain the capacitors.
3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and
hold down it's power button. Electricity can remain in capacitors and on circuit boards
enough to prevent normal functionality. By clearing the residue electricity, your product
will have a fresh start and many times this will resolve a buggy or non-responsive device
that appears to be dead.
If this doesn't resolve the issue, it's possible the power supply is on it's last legs.
I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.
