    Samsung ps50q91h clicking noise, no image/sound

    Hello

    I have a Samsung ps50q91h 50" Plasma from 2007, it just does a clicking sound, trying to boot up.
    I've already replaced the capacitors, one was leaking but not buldged and the others were a little bit buldged.

    Still the same problem, please see this video with this problem, the noise it seems to come from those 2 blue components or the black ones.

    Any ideias?

    These have some common faults. Endless clicking could be bad or cracked solder joints on the heatsinked transistors etc or they have blown already due to this and psu will need rebuild. If you search the board part number in badcaps good chance you will get some good posts to read.

    It will be bn44-........ on the white sticker

    Other issue these have is theymain and uppet buffer blows

    I have one that blew the ymain buffer and psu in one hit or maybe the psu blew aftr repeated attempts with bad ymain.

      Samsung UE48J6200K - No image but sound
      by Francesc V.
      Hi:

      This TV turns on and it can show picture for some seconds (sometimes minutes) then picture freezes and fades away. What I've seen so far is that the T-Con (BN41-021101A) starts with three leds on, but as soon as led3 turns off, just 12V and 3.3V (the bold ones) remains in the PCB but all others disappear.

      If I remove the 2 bellow ribbons, LED2 never turns on. I was trying to look for the "T-CON ready" pin to shorten with 3.3V and then test just the TCON without the panel (haven't found it yet)

      Not sure how to proceed here..............how can...

      [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 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...
