    OK. The PSU is OK. So what you are saying is that when you disconnect the Y-main Bd. the PSU does not click anymore. You may have a bad Y-main Bd.

      Thanks for your reply. How can I be sure it's a board issue.

        Disconnect the Y-Main from the PSU. Do a diode test across Yfr and Yrr and test the ohms reading from GND and the Vscan test point. Report your findings.

          Samsung UE49KS7000SXXH - fast clicking sound in standby mode
          by B0r1s
          PSU - BN44-00878A

          Symptoms:

          The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
          A weak clicking sound was coming from the transformer.

          Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA

          Progress:

          After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I...

          [SOLVED] M1 MacBook Pro clicking sound logic board 5V no power on A2338 820-02020
          by slimmy182
          Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).

          I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).

          Looking on google I found this:...

          Samsung UN70NU6900F no picture and no sound
          by jchang
          Hi all

          I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



          Symptom:
          No picture no sound.
          When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
          No sound at all.



          What I tried:
          1. I tried unplugging the left or right ribbon...

          Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
          by Ierwin
          Hello everyone,
          Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
          The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
          He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
          I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
          Anyway I still fully expect that there has been something seriously damaged...
