I have found that the LN series of Samsung TV's have several power supply issues. Sometimes you get lucky and it is just the capacitors but other times the regulators or damper diodes fail. This isn't something I would tell you to fix on your own. These SMPS are very sensitive and if you get in the wrong area you may end up having to replace the whole board instead of repairing it.

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.
