You have a part going out on it, I had the exact same problem and it was more to get it fixed than it was to buy a new tv. I don't remember what the part was but it was expensive. Mine started doing that right after the warranty ended, and they won't fix it for free. Good luck with it. And I would stay away from their products in the future

I have not experienced this problem with my TV. My TV is plugged in all the time and comes on/off each time I press the power button.

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?

The bigger problems with the Samsung TVs is the soldering on the power supply and/or transistors going out. But my Samsung would just turn itself off then back on (I never unplugged and re-inserted the power cable). I did buy this cord later when my original cord shorted out and melted. If it is the cord, then that's a cheap fix...if its the power supply board, you're looking at $100-150 for repair or replacement

Hey, I had the same problem with an LN55C650 and even with a new panel it did it. So the tech got on the phone and called and was told about the service bulletin and cut jumper number p854 on the 55" and that fixed it. So the new panel came back out but I got my tv fixed. Yay!!!

I suggest you call the manufacturer for advice so that you do not damage the TV. Please let us know what advice was given for the good of mankind in case any of us get in the same fix.

I had the same issue (turn off after a few minutes). I called a Samsung tech rep and they told me to replace the bulb. I did that and had the same issue. I called Samsung again and they recommended I replaced the ballast, so I bought this and replaced it and still had the same issue. When I called Samsung again, they said I now have to take it to someone for service because the control board had to be replaced. I decided it wasn't worth any more money, so after over $100 in parts and a few hours of my time, my TV ended up in a recycling center. If you have a Samsung DLP, you can look through some online forums and see that this is a common problem with these units. I had the same issue (turn off after a few minutes).

yup i have the same issue apparently its cause of the tv drawing lot of power dur to its fast start up . try plugging it in to the wall direcly ie with no other devices plugged in. i also notice that it only happenes if i have had the tv off for a while eg over nigt and not if it turn it off wait a few mins and turn it on so it must be some thing with the power. i would still call samsung and see whats up.

Remove m power, plug tv directly into wall and see if tv turns off. If it doesn't turn off, your m power is over heating and possibly shorting out. It's very possible that your tv is over heating as well. Remember these conditioners only clean and stabilize power.Hope this was helpful

Unplug the power and plug it back in. If you don't see a picture, it might be stuck in the wrong video mode. If it is, you might not be able to fix it without plugging it into a television that supports the mode it is currently in.

I haven't noticed it rebooting. If I turn off the tv my show is still paused when I turn the tv back on. It could be the tv, if it doesn't keep constant power to the mhl port when off.

The problem that we are having is that our TV (LNA650) takes forever to come on. The music plays and the lights flash (this morning the count was 56 times before it finally came on. We purchased it in 2008 and the problem just started) Customer service is no help--Anyone??

Exactly the same happened to me! I bought this TV for my dad and I was so disappointed when we couldn't turn it on.

Unplug the TV for at least 3 min. Then hold the power switch on the tv it will be blinking and hold until it stopped blinking which is on. It should work. If this does not work you may have to get a service man as it may need a new mother board. Good luck.

Cesar, I found that it won't work if I connect it to a TV that's already on. connecting it before turning on the tv has worked for me.

Try removing the power cord completely, from the tv as well as the outlet, for a half hour or so. It may be a static electricity build up, which needs to drain off.

That would be the plastic on the bulb getting got which means you have ran the TV too long these televisions run got when left on for extended periods of time. I only run mine for three to four hours at the most then I give it a break so as to let the bulb cool off. If you find the light blinking on the front after doing so unplug it wait a few minutes and then plug it back in and the light should be off I hope this helps

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.
