whats the EAX/EBR number for your zsus i have one thats working if tom says its your zsus

Re: 42PJ350 clicking noise
Hi tom
both probes on resistor 00.1 hold few seconds go to 00.0.Last edited by marty-clubber; 10-27-2014, 04:41 PM.Comment

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.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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.Comment

Re: 42PJ350 clicking noise
which location on the Y-SUS are these located and are these tested in circuit?Comment

Re: 42PJ350 clicking noise
Location
R607,R729,R503
No they been removed mateComment

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.Comment

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 ?Last edited by del3165; 11-14-2014, 11:22 AM.Comment

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.Comment

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.Comment

Re: 42PJ350 clicking noise
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 ?Last edited by dhavalrpatil; 06-01-2017, 05:11 AM.Comment

No power
i have the above ps which i change the TOP258eg ic.
Now i have power but is clicking and voltages are flutuating. I change all capacitors, i test all mosfets and all are ok.
i am wondering what is the value of R901! I am getting 0.5Ohms. Is that correct!
the colours look like R,R,W or silver,G Bl.
Thanks... -
Hi all,
I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.
Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line.... -
Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.
Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.
There's some logic behind it. As soon as I select an input I get only left...04-23-2025, 10:09 PM -
Hello
I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.
Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.
I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board
Removed each of tyhe boards

Hello!
TL;DR: Replaced blown Q801, Q802 and fuse, but it didn't fix the problem.
I'm trying to repair this TV, since it developed clicking symptom. I disconnected Y-SUS and Z-SUS boards, but PSU was still clicking, so then I was sure problem lies in PSU. When you plug it in, you can hear 2 clicks from relay and then one click when it shuts down. I found two shorted mosfets Q801, Q802 and blown fuse F801. I replaced those elements, but it's still doing the same.
After some research, I found out resistors R108-113 need to be checked and sure one was showing...
