Ysus board mate I have the same tv up stairs put the ysus board in working fine
cheers any way.

Hi tom
both probes on resistor 00.1 hold few seconds go to 00.0.

Re: 42PJ350 clicking noise

Well, ok...
I SUPPOSE they could be bad...
I would be personally surprised, but if you like, try swapping them.
2.2 ohm 5%, 1W or 2W rated, flameproof/NOX type.

Re: 42PJ350 clicking noise

Ok
Tom Just order some new resistors post back let you know, personally don't think it going fix it! worth a shot.
Have the same TV up stairs that how i know ysus board Faulty
could i test most of the circuits on the good board to the faulty board in circuit?

Thanks tom you been really helpful
excellent site.

Re: 42PJ350 clicking noise

which location on the Y-SUS are these located and are these tested in circuit?

[marty-clubber]

Re: 42PJ350 clicking noise

Location
R607,R729,R503

No they been removed mate

Re: 42PJ350 clicking noise

Cool I just wanted to know the locations just if I have this problem.

Re: 42PJ350 clicking noise

Hi just updating changed 2x 30j124 2x 30f124 3 faulty resistors R607, R729, R503 Ysus board.Now the tv up and running
Thanks guys for all your help.

Re: 42PJ350 clicking noise

Decided to have another go at repairing this set. I was sure it was the power supply. I have changed most of the caps and the most common failing components except the 2 resistors which I checked out of circuit. I put 2 100watt bulbs on the output as per service manual and was going through the other tests when the bulbs came on. Reconnected the connector to the Y-sus board and the tv came on fine. Put the cover on and the tv started clicking again but comes on after about 10 min.
Is it usually a capacitor that would cause this ?

Changed another couple of caps on power board which tested fine out of circuit and looked ok. Tv now working fine.

glad you managed to fix the set and all seems fine now but when you tested the caps off the board did you just test them with a capacitor meter or did you use a esr meter?

Re: 42PJ350 clicking noise

I used a fluke meter which can test capacitors. I retested the capacitors only one seemed very slow giving a reading. 3300uf read 3815uf.

Re: 42PJ350 clicking noise

I too have the same problem. I have also changed all the normal components that go faulty on this power supply. But despite all of this work the power supply still clicks and refuses to start. It is power supply related because it also clicks with no other boards connected when forcing the board to switch on.
I was interested to read the post by Del3165 regarding changing a few few capacitors that eventually resolved the fault. If your reading this post Del3165 I would be interested to know whether its still working ok and if so can you remember the which capacitor when changed cured the fault.

Tv working fine . I tried everything recommended before changing the caps. I changed all the caps apart from the 2 very large ones.

Glad to hear your TV is still working appreciate your reply

Hello i have same problem with 42pj350 supply just clicking. i replaced 3br1565 diode 304 but i got same result there is no vs va some time i switching it give vs va but after on off it agian clicking. Which caps u chaged will u tell me@ del3165 ?
