Samsung plasma TV never stop clicking pn50a510p3

[hmendez86]

I did research and shoppjimmy had a kit for main board I order it and install and still doing same thing.. what I think the problem here is the power supply...I check the sntby-5v and is ok....no vs, va nothing at all...I check from rectifier to transistor and they seem ok I have soome measure ackward numbers they have 5leg transistor ??don't know how test them...any clue???? Am pretty sure not the main board.....how can I test the power supply alone to be sure.....is working.

Your power board will be the BN44-00222A ? And it shows a green LED flash code when faulty, you will find it screen printed on the bottom right corner at the side of the little board that stands up, check code and get back

Test the board by removing all plugs apart from mains in, you need to find PSon pin on white socket (bottom right) you say you have stby but check it again same socket? if thats Ok make PSon low (ground it to chassis ) that should bring the relays in,and give you all the low voltage outputs from the board, if this works then find Vs on pin and with a resistor (470-1000 ohm) make Vs on high (jump to 5v stby ) this should bring up the Vs voltage and complete the power supply test. report and let us know how it goes

So I jump( Ps_on to ground) and should power the relays???

Yes with mains supply from wall socket and all others unplugged if you have stby 5v and make PS on low. relays will come in,and all low voltages should come up
