    Samsung PS42C450B1W CLICKING sound.

    I have this tv which once connected to power it clicks and won't display standby light.

    If i isolate the power board it doesnt click anymore. And there doesn't seem anything wrong with the board. Looking for some pointers thanks. Photos included

      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...

                  Onkyo-593 No power and now clicking sound
                  by Sisko
                  Hi all!!

                  Ok just got a Onkyo SKW-593 sub woofer that has no power person told me that it smoked and that his GF let the volume full when she powered off the amp and when he came to turn it on the sub played but then suddenly smoke was coming out, didn't say from where. So opened it up and saw a resistor made of metal (pic) but can't see any writing on metal par so what ever was written on it was burnt. So I'm kinda stuck here with this. I did ask for a repair or schematics in the other group section and waiting for this but I hope someone here might lend me a hand to try and identify...

                  [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...
