    pn50b450b1d clicking

    The tv clicks and sometimes makes the chime sound but will not power on the whole way.

    Va and Vs don't have any voltage.

    When i jumper the board i only get 168v on the main caps when powered on.

    I get all of the correct voltages on the connector that goes to the main board.

    The power supply is a bn44-00274a

      I ordered a new power supply and the tv powered up but it has some horizontal black lines.

      Is there a way that i can narrow it down to a bad panel or y sus or buffer problems?

          This sounds like a Y-SUS and Y buffers problem. I would recommend changing the Y-SUS and Buffer Bds. together.

              Samsung PN64H5000 clicking when powered, then stuck in standby
              by meeotch
              My PN64H5000 shut itself off/on/off a few times in succession last night, then refused to turn on again. When I first plug it in, I get five clicks coming from the power board, and the red standby light on the front goes on and off, as does the little green LED on the logic board. After that, the red standby light comes on after a couple of seconds and stays lit, but the TV will not power on. Confirmed by leaving it unplugged overnight.

              I opened it up, and didn't see any bulging caps, burnt PCBs, or anything else obvious. Tested the two fuses I saw on the power board (one removable,...

              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...

              Carver CM-1090 - Power relay clicking on & off, then fuse blown after 20-30 seconds of power cycling.
              by beetle1303
              I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.

              On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off...

              [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 UN39EH5003FXZA won't stay powered off
              by Hannibal_Hector
              Hello,

              Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown...
