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?

If it's like mine, I start on HDMI when I power it up, it switches on its own to TV, then I have to press HDMI, so it sounds like a similar problem.

My set never had the picture issue prior to the issue of the tv switching off entirely and not coming back on. I tried the side power buttons, and I also called Toshiba customer support whom walked me through holding down the power button and unplugging the tv for a while, etc. They were unable to help, so they directed me to my local repair shop. Called them, they seemed helpful, were supposed to order a new power supply for the TV. Haven't heard back from them...but after leaving the tv unplugged for a day or two, I plugged it back in and its worked ever since like a charm...have no idea what the problem was, but it works now...just hope it stays this way.

We've had the same issue. The TV (which we've had since January '08) had been doing that for 2-3 months. And, it's taken longer and longer to come on. It would make a clicking sound and the small red lights on the right side would go on and off alternately with the light on the "on" button at the base of the TV. Yesterday, it took more than 5 minutes to turn on. Then, today, it stuck in the clicking mode and wouldn't come on at all. We completely unplugged the TV and left it unplugged for several minutes--hoping that when we plugged it back in that it would be in the "off" mode. Instead, it's continued in its clicking mode for nearly an hour, now. Fortunately, we have the extended warranty. And, a repairman is coming here this Thursday to determine what's wrong.

I have electrical and some electronics background. I don't believe a new cord is your answer. It sounds like an internal problem with the tv. If the tv works fine after plugging back in until turning it off, then it's not the cord. By unplugging and plugging back in you are basically rebooting the tv that is failing to do it itself after turning it off. If this is the case, you would need to take it to a repair shop. I hope this helps you.

It may be the lamp, but it sounds more like something else that is causing the TV to overheat. I had to replace a board in my DLP a few years ago when it did that - would have been expensive without insurance. If the light is blinking after the unit turns off, the sequence of blinks is sometimes an indicator of the problem, so check your manual. Good luck - may be cheaper to buy a new TV!

You need to turn it on whenever you turn on the TV, and sometimes after a period of inactivity it will go off and you have to re-turn it on. JK

You don't have to unplug the unit. Simply hold the power button down for 10 seconds and it will switch it off. Press the power button again and the problem will be resolved. This is a handshaking problem between your HDMI device and the receiver.

My guess would be the bulb is bad.It's easy to replace but you may want to call a local tv repair place if you don't feel comfortable doing it yourself

You might try replacing the batteries. If you don't turn them off every time the batteries run down real fast. Also, the light will turn red when you put the TV on pause. Hope this helps.

yes, you are going to need to take it in to a repair shop. If you do a search on the internet you will find many others that have had this problem. TV's now days don't get repaired in the true sense. complete boards are just replaced

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.

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.

Sounds like a real tech support question. When you turn it on you should see the logo appear. If it appears then that is a good sign that your TV is working. Try different combinations of input. Cable, HDMI, etc. See if you can get any one of them to work. And don't forget to choose the correct input on your TV.

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'm having the same problem and it's intermitent. Sometimes it works and sometimes it doesn't. When it doesn't work, I have to turn the TV on and off several times and then it will work. Then sometimes the TV just turns on by itself. We have a Samsung technician coming tomorrow to check it out - hopefully I can post the solution...
