The power supply will sense if the set is 'drawing' too much current and switch itself off. This could be the case here. The power supply board may eventually go completely bad.

There is no guarantee the problem is the same, but it is likely. The TV is different and the power board layout will likely be different, but the concept is the same.

In addition, it is possible that the problem is not in the power, but in the main board and if so it may not neccessarily be a capacitor.

But hey, it works one step at a time...

Call Samung customer service, they are doing this repair for free. I had the same problem at 11 months, they replaced the power supply board under warranty. At 2 years I had the exact same problem again and this time they replaced 2 - 50 cent capacitors on the power supply board. It took the repair man less than an hour and he had the replacement capacitors on hand. The original board and the replacement board they gave me had capacitors that were faulty. Hopefully these new capacitors will last. I have to say that I was thinking (no more samsung products for me) but I got excellent customer service and they admit that they had a faulty product and they accepted responsibility.

When I try to turn on my Samsung LN-T4042H LCD HDTV it is now constantly clicking in a continuous loop and will not immediately turn on. It started out small- a few clicks yesterday morning. Today it...


There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.

Power won't come on- constant clicking loop instead


My T.V. did the same thing and it was due to bad capacitors on the power supply board. the tops of the capacitors were bulged, once replaced it worked fine. It involves sodering in new capacitors total cost $30. that includes buying the sodering tool. Keep looking around on line someone had pictures step by step how to do it.

This may not really be a solution to your problem, but here it goes. If you are not sitting a particular distance from your tv you will experience slight pixelation. I have this tv myself and I think it looks great. Now when I am sitting up close on a station that is broadcasting in 720p(which is pretty much every HD station) It looks only pretty good...I sit back and it is fantastic. The good rule of thumb is take the number or inches your TV is in yours and my case 40, divide by 10 and then multiply by 2...and that is the number of feet you should be for optimal viewing distance. So 8 feet, you would be surprised to see how sitting this magic number away makes a difference.
