Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Ok, So I got a new X-SUS board. But this time with only 3 big capacitors on the left side and right side. But the numbers were the same. I had everything connected except the wide panel cables leading to the X-SUS connected and the TV(all the boards) started just fine. But when I connected the wide panel cables to the X-SUS it shorted again. So I guess my panel i shorted?

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
What caused these transistors to short? Do I risk shorting out the new ones that I solder on?Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Okay, I just checked my old X-SUS board and there were also transistors shorted. I took a picture and marked where I found the faulty transistors and what name they had.
1pcs of RJP30H1
3pcs of 30G124...Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Isn't the best strategy here to focus on the X-SUS board? I has obviously been sent a faulty board with shorted transistors and the old board remains to be checked for this. Why would the PS board be faulty when the TV doesnt click anymore when all the board are connected except the X-SUS and to add to that, I have replaced the PS board.Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
I'm not following. He said:
ps-on to Gnd
Vs-on to 5vstby
I can't find any 5vstby. Can you draw lines in paint where I should put wires?Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
So what is my next step? Check all the transistors on the old X-SUS board and see if I can combine all the working transistors into a good working board?Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
And what should it show in both directions?
All of the rectifiers on the eBay board showed 444 in one direction and infinity ohms in the other direction.Last edited by Hatmpatn; 03-24-2017, 06:19 AM.Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
I now tested all the "three-legged" transistors on the Y-SUS board and all are good! I didnt test the few two-legged like the picture above because I dont know what they are and how to test them. What is my next step?Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
I have taken off all the transistors from the eBay board and some really behave strangely. I have tested like this:
1. Put the multimeter on ohm reading, scale 2000k.
2. Put the negative lead on the leg to the right, seen from the front of the transistor
3. Put the positive lead on the middle leg. See that I get infinite Ohms.
4. Put the positive lead on the left leg instead and then back to middle. See that the circuit is closed(get 0ohm or something other than infinity).

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Okay, I suspect so aswell. Am I now supposed to disconnect the cable leading to the logic board and the cable leading to the mainboard and jumper the PS_ON to GND on the mainboard connector on the power supply and jumper VS_ON to B5V(Cant find 5VSTBY) on the logic board connector on the power supply?

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Nevermind me. I think I know found it out by myself. I jumpered the pin 3 and 4 on the logic board and disconnected the "fine cable" running from the logic board to the mainboard. Still there is the clicking. I also tried disconnecting the power wire running from the power supply to the main board, but then there is just a dead TV. No LED on the logic board and no clicking.Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
Ok, have put it all together now. No harm done. How do I go about jumping my power supply on and run test patterns?Leave a comment:

Re: Samsung PS51D535 Plasma - Clicking - Impossible problem
I thought that maybe the Reference difference on the board mattered so I transfered all the capacitors from the new board to the old board. But what else could it be?Last edited by Hatmpatn; 03-23-2017, 05:05 AM.Leave a comment:

Samsung PS51D535 Plasma - Clicking - Impossible problem
Hello! I'm having a real hazzle with my Samsung Plasma TV PS51D535.
It clicks a few times and then stops. Screen is black.
The wiring is as follows on the TV.
I have tried disconnecting every board to the Power Supply.
The clicking stops and the TV seems to boot(I have no sound on it) [B]when I disconnect the X-SUS![/B]
1. I first ordered a new X-SUS board from ebay. My board is LJ41-0422A(LJ92-01759A) Rev 1.2. The board I got a hold of is LJ41-0422A(LJ92-01759A) Rev 1.3. [B]The problem remained.[/B]
2. I then replaced...Last edited by Hatmpatn; 03-23-2017, 05:08 AM. -

Maybe a proper introduction will work then. 27-year old Biomedical engineer from Sweden with a special interest in electronics. I never throw away a broken electronic device but has an urge to disassemble the whole thing to see what is wrong. Looking forward to my time on badcaps to help and to be helped.Leave a comment:

Re: New Members - please post your introductions here
I came here in order to get help with my impossible problem with my Samsung Plasma TV. Nothing helps. Replaced all the boards but still nothing. Think I will create my thread now
