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.

SOURCE: My samsung tv turns on and off repeatedly at

Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

Howdy,
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 CM811, CM812, CM817 & CS806; 1000ufd 25volts.

Good Luck, Big IRISH.
