Three capacitors on the motherboard are bad. They cost about 2 dollars each. If you are handy, you can take the tv apart and replace them. It took me about 30 minutes. Unplug the tv. Lay it on a large table so the stand can hang off without tilting the tv with the back of the tv facing up. take all the Phillips screws off the back cover. Take the back cover off. There is a grey cover about the size of 8x11 inches on the left middle area held on by about 6 to 8 phillips screws. Take it off. Unplug the motherboard, there are about 5 different plugs. Unscrew it and take it out. There are 3 somewhat swelled 1000mf 10v capacitors in the upper area of the motherboard. Replace them with 1000mf 16v capacitors, soldering required. Make sure you install them with the ground in the proper hole. Put it all back together and you are fixed for less than ten dollars. Samsung should be doing this for free. It really makes me mad that they can put out such an expensive product and not accept responsibility for a potential fire hazard. I will make sure anyone who wants my opinion about an electrical product knows how bad samsung is. Good luck.

I just fixed this very same problem. The capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

I have a Samsung LNT4061FX/XAA Serial no. AHBA3CSPA03617J. The TV will not turn on. It just continues to Click and the Red light in the front goes on and off. Is there a part available to fix this problem?

Regarding the problem with LNT406FX/XAA models not powering up - I contacted Samsung @ 1-800Samsung and they issued a repair tag and put me in touch with a repair company that came out the next day and replaced the capacitors on the power supply. Apparently Samsung got a batch of bad capacitors from a supplier and they know which TVs by the serial numbers. My TV was 28 months old and there was no charge. TV works fine now. Good for Samsung for acknowledging they had bad parts for and getting the tv fixed at no charge.

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.
