So on Tuesday morning my slightly out of warranty Samsung LCD started acting up. It would get in a power up loop. You could hear the relay's click but the main processor wouldn't boot up. Then it would click off. It would repeat this loop for sometime and eventually startup. But it gets progressively worse.
Samsung will get about $150 or so for a new powersupply but you can fix it yourself at home with a soldering Iron and about 10 cents worth of parts.
Lay the TV down on it's face and pull the back off.
Disconnect the powersupply and remove it from the set.
There's a series of about 6 black capacitors near a heat sink on the upper rh side of the board. It's usually the 1000mf 10V capicators that go bad. Look for ones where the top is bulged or even split open.
Samsung used 10v electrolytic capacitors in the powersupply, Replace them with 1000mf 16V capicators for a little more reliability. The 16V will take more heat without degrading. Since this set of caps is near a heat sink they need a little extra reserve
