My guess is that the tv has no inverter(s) !! Its a plasma ! not a lcd.
I do not have an answer because the problem could be caused by many things...sorry...
My best guess would be :the power supply...

Philips 42PFL5603D/10 relay clicking


Relay is on or connected to power supply--if clicks on and then off something (most likely on power board or something it feeds) is bad.

Some voltages from standby portion of power supply can be tested but since no paper schematics for this brand it will be hard.

Philips Magnavox 32MT3305 keeps shutting off with relay clicking. The green power light stays on but the picture and sound go out right after the orange status bar goes away. If the channel up or down...


the relay is the safety protective device..sometimes a defective component or something. maybe an overloaded power supply might caused this problem..so before any thing could gets worst..the relay will shut the unit..

Toshiba Color TV Relay clicks slowly. TV does not come ON.


Electrolitic Capasitors in the power supply going or being bad will cause this. At some point a low value resister also will start to run hot or burn up. I believe it it a 16v 1500 uf cap near the relay. I would also replace any 10uf 160v caps in the powersupply too.
Hope this Helps,

Hyundai plasma model HP-4200


Hello ****, I have the same problem. However. I manage to get the TV on by pulling the cable out and then plug it back in again several times. A couple of times just after you have heard the first click and the a couple of times just when you hear the second click. Sudenly the TV decided to work again. I think it must be a problem with one of the two relays that sits next to each other near the centre of the TV. If you take the back of and then plug the power back in you will see the two lights next to those relays come on and then die out when the relays let go. This is what hapens if the TV doesnt work. If the TV works those lights/LED's will stay green and the relays will hold on and feeding the TV screen. I will probably try to see if I can buy replacement relays and replace these. If I can get hold of them, then probably I would take the existing relays appart to see if I could see any fault. If those relays ar ok and the replacement relays appear in the same manor like the old ones I would look for problems before those relays. Maby order a new circut board from Samsung.
