SOURCE: Samsung 50" plasma won't turn on
My 42" plasma is making a clicking sound, then it switches off and keeps clicking but not switching back on, when it does go back on it stays on for just a few moments, it is only 14months old.

I just fixed this very same problem. It is 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.

Check for bad capacitors in the power supply. The capacitors will be bulged on top. Typically there will be 3 or 4 caps with this problem. Thanks for using fixya.

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.
