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.

I have the same issue with my two-week old 42B450, as well. The plastic bezel makes faint crackling noises as the unit warms up (lasts for about 30 minutes). It is definitely the plastic bezel since I can duplicate the sound by pressing the bezel along the top edge of the TV. Another Amazon post said that they had the same issue and so they returned the TV for replacement and the second one did not make the sounds. Am curious if the Samsung rep mentioned above actually has a fix for the problem.Except for this issue, the TV is excellent in every way.

Do you hear a clicking? If so it could be the lamp ballast trying to start the bulb, the bulb may be defective.Also if the fan ventilation grate is not on properly , or being blocked therefore unit overheat, the tv will not go on.Tell me what you're symtoms are.

Mine was turning off and then automatically turns on in few mins. Most of these problems in Samsung TVs are due to its capacitors in the power board. I dont know if your TVs issue is the same but looks like due to capacitors. I would just try this kit and it is not that hard to replace them. The kit generally has more that what is required. I just replaced all in my mother board that matched what is in the kit and it worked for me.

My first bit of advice would be to isolate the source of the problem (is it the TV or converter?). Try hooking it up to another TV (or a friends, etc). Incidentally, I have mine hooked up to a Sony TV - works great (knock on wood)...Good luck...

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.

i guess calling samsung would be the best thing. maybe it may be a power issue. the tv does suck up a lot of power at start up. but then again 5 seconds is a long time. the tv should not take that long to come on let alone buzz

I sent mine back for a full refund. I was with in a month of sending it back. Contact Amazon and see what they can do for you. Then look for a different lamp manufacturer and test the lamp right away. Or if you can afford a new tv I would do that since they are phasing out these types of tv's. There is no vested interest in making a good quality replacement lamp. That's why they are so cheap these days. Hope this helps.

I would advise you to call the customer service on the back of of the TV. I have called them a couple of times and they have been extremely helpful.

I haven't had any problems with mine, but I did have a similar problem with another model and this is how it started before the whole screen went dark. I had a technician come by. He said it was the mother board and that he would fix it but he couldn't guarantee it wouldn't happen again. He said that it's best to replace the mother board, and if you have to do that you might as well buy another tv. I took a chance and he fixed the problem temporarily, then it died, so I threw it away and bought this LG. I've had it since July 2013 and it's worked fine. Mine is the same model in a 50-inch. I did buy the 5 year warranty just in case since it's new technology. With these smart tvs it's best to get the warranty because you never know. If it's still under warranty, you should return it and have them replace it before your warranty expires because once the mother board gives out it's too expensive to fix and you're better off buying another tv.

Rick H, It sounds like it will need service. Reach out to the Samsung customer service center to try some troubleshooting. If that doesn't work, they can set your TV up for a repair. Thanks for your support of Samsung products. --Mr. S

Unplug it, wait a minute or two and plug it back in. I had this problem as well and it was happening a lot, so I returned my tv for a LG...great move, no problems since.

Vickie, In the end I was not able to resolve the issue. I had 2 technicians out to try to fix it, but they weren't able to. Sharp is sending me a new TV (which is being delivered tomorrow afternoon). I'll let you know if it works any better.

My tv was just picked up! Called Samsung and got the same response they gave you - a repairman would come out and if it couldn't be fixed it would have to be sent away for service. As you, I did not think I needed to have a brand new tv sent out for repair and decided to return it. I am now watching my old 19" set (gave my 26" away when I got the Samsung!). Have you had any luck yet? I am considering Toshiba.

i just took mine into the shop for the same problem, very irritating hearing it turn on and off all the time just to start, it would take like 10 minutes for my tv to finally turn on, the technician at the shop said the power supply was bad and i wasn't getting enough power to the main board to turn the TV on, 200 bucks later, I am happy, fix it, it is worth it.

Call Amazon to return the tv. I just talked to them about exchanging a tv for another one, but they said they can only refund and then I'd have to purchase new. They said the only way they exchange is it one was damaged and then they would send you the same model.

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.
