Tv is turning off and on until warmed up, what is causing this?

I had same problem 3 times during first year with vertical lines and tv constantly reboot. If you have same issues this means your tv broke and need to be fixed. Register tv with samsung and schedule the technicians for repair. If it was sold by amazon you have warranty if not you may not have it. If you tv more than 50 inches tech will fix it at your home. Good luck

My tv was going off & on from background noises. Turned the voice activation off to resolve that issue.

I have not had that problem, sorry hope you find out what it is, maybe its normal for your TV.

I don't think so, It seems like your power ballast may be getting a little old, Check for the dome shape on top of the little barrell on the circuit ballast if it is domed upwards thats a sign of a ballast about to go bad. If not I would wait till the Tv goes out, It could stay like this for a long time. Hope this helps

There are several possibilities. First I would check the power cord for any damage. Does the tv not power on after being on or was the tv powered off for a day? If the tv is on, does it shut off on its own?

It's the bulb warming up 99% of the time. If it never goes away then check your HDMI cables by taking them out and reinserting them. Do this for all your electronic equipment because you never know which one it could be.If the blue/green tint never goes away after the above it's time to call mits.

To be honest, I have never paid attention either, however the light bulb has a cooling fan to keep it cool while the TV is on and a minute or two after you turn it off. If the fan is defective, the area where the lamp is located will be warmer than usual. When you turn your TV off after about half an hour of use, get close to the TV and you will be able to hear the cooling fan on for a minute or two, if not, the bulb cooling fan is defective, and the life of the bulb will be short.

Yes, I am having the same issue with my same model television. Mine was purchased the end of 2/08, it started doing that about a month ago and it is out of warranty. Have you had your repaired? If so, what was the cost? wants $150 just to come out and diagnose the problem.

Your power supply to the bulb may have gone out, but that does seem to be too much of a coincidence to go out now. I would personally try another bulb even though it means spending more money. If it is the power supply that has gone out to that bulb, from what I hear you will probably want to consider getting another television set because they are extremely expensive replacing or to repair the very sensitive and very specific power supply. There are no generic power supplies for the TV set as far as I know. Notice all the varying ratings. I notice the latest ratings are mostly all negative. When I replaced my bulb September of last year, it was provided by another distributer than is now through Amazon. That may have something to do with the quality issues and I would be willing to bet your bulb was dead on arrival. Use Amazons email to see if you could send it back for exchange. I did not notice what kind of warranty was offered. You should get at least 14-30 days replacement period for defective merchandise.

I experienced similar problem. Day 1 fine, afterwards there is always a problem starting "cold" with picture from cable box (connected via HDMI). Image can be terribly distorted. It is fixed by toggling to another input (say, the Blueray player), then toggling back to the cable. Or, just waiting for a couple of minutes and changing channels. I have a few ideas: 1) "Handshaking" problem between TV and cable box HDMI. 2) HDMI connection not quite right but after expansion via heat, it resolves. 3) TV itself maybe has some bad electronics or capacitors that need warming up time....perhaps the energy saving features are too close to the edge. Would love to hear back if you solve. I experienced similar problem. Day 1 fine, afterwards there is always a problem starting "cold" with picture from cable box (connected via HDMI).

Yes, they basically worded it incorrectly in the instruction manual. Enabling this feature will remember the On/Off state of the TV when it loses power. So if you unplug it while it is turned on, it will turn itself back on once you plug it back in. It has nothing to do with the video signal. I tried the tech support people and even they weren't aware of this.

Mine turns off after the same period. Not sure it actually goes "dead" because the TV signal still seems to be amplified, but the display powers down.

The problem is with the HDMI protection system. Next time turn off both tv and soundbar the turn tv on first then the soundbar. The issue is what they call a handshake problem between tv and soundbar. Good Luck

I checked the front of my TV in response to your question and it isn't warm and my bulb works great too. Is the tv warm when it is turned on or all the time?

I would check the pins to see if they are broken. Could be a bad cable also check it with another tv if it works fine with another TV could be the settings for the tv.

It is the plastic heating up nothing to do with the power if we are talking about the popping noise common after the TV has been on for a period of time and continues when it is turned off. I noticed when my air conditioning turned on it became more intense b/c of the contrast in temperature. You can move the TV or turn it off a couple hours before you sleep i guess thats what i've done is turn it off an hour before i go to bed.

Hard to say without more info. Was it it hit by a power surge? I don't know about this particular model, but I had a different Samsung model TV that this happened to and I found out the power supply went bad. I figured that out myself by taking it apart and probing around with a meter. But, I am an electrical engineer and not that intimidating to me. I found the replacement power supply board online for $150. I replaced it and no problems since. If you problem is common for your model, you'll see it everywhere on the internet if you Google it. That is what pointed me in the direction to look on my TV.
