SAMSUNG PLASMA POWER SUPPLY CLICKING.


If you have a Samsung Plasma PS50A550 which will keep clicking and not come on, the fault is in the power supply .Check Power supply if its a BN44_00222a. This PCB cost almost $ 300.00 can be fixed for around $ 30.
The fault is in the 5.3v supply to the T.Con PCB. On the Power supply check voltages.VS will not come on unless the T.Con pcb is active.
Check on printed circuit side of PCB on secondary side there are 3 IC close to one another. 2 IC'S are 8 pin and one is 16 pin. Replace both 8 pin reg IC (25h3ll ) these are available from RS components. Part number is STS25NH3LL. The 16 Pin IC is a L6725A but this is not faulty.
lets keep these good TV working for another 4 years.

Please check the flat cable connections between TCON board and the LCD panel. If this is ok, then it is either the TCON board or the LCD panel itself. Good luck.

Check and replace the backlight inverter board. Do not think that it works only with some capacitors. The inverter transformers are the main component on that board, and always gets shorted inside, and is irrepariable.
