Question about Televison & Video
Re: Plasma tv mod. # ciwp4206. Unit has no power. When I try to power it up, relays click, a faint squeel is heard, and relays click back. No power. Inside of unit looks like Samsung. Any suggestions?
The squil could be a cold solder joint on the heatsink.Pull the board or boards,out enough to see if a cold solder joint on a heat sink is there.The factory sometimes mess up.If you find a cold solder joint on the back side,underneath a heat sink,just clean the area real good(use contact cleaner)and resolder the heat sink leg,back to the board.Hopefully this was helpful.

Balast may be the squeal, an overheated capacitor, or a relay itself. You can test each with an ohmmeter to determine which is faulty. The most common cause is a faulty power supply, due to faulty internal capacitors
