    Phillips 42pfl3603d/f7 Constant Clicking

    Hello, I have a Phillips 42 inch Lcd tv. As soon as i plug it into an outlet it begins clicking. I assume it is trying to cycle on and off. All 12v pins seem to have the correct voltage. right about 12. The one that I did notice that was wrong is the 3v3 st. As the power supply clicks the voltage fluctuates between 0.90v up to 1.5v. It changes almost every time it cycles (clicks) On the (off) cycle it drops all the way to zero and when its cycles on it never goes above 1.5v. It continues doing this as long as I leave it plugged in. I see no visible bad caps. I believe I have isolated the click to a little black box. I will add pic. Any info on where to check next. Thank you in advance.

      Problem

      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

      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...

      Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
      by JimBanville
      The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
      Opened it up and discovered the power supply is making a faint clicking or ticking sound.
      I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
      I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

      [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:...

      (old) LG 32lk330 cycles Backlight 3 times and then OFF
      by edugimeno
      Hi!! I have been given this old TV set.
      When I hit the power button, the BL (as you know this is a CFL backlight) turns on, video works fine as I can see the LG logo show off, but the backlight starts going on-off for 3 times, when it gives up and turns completly off
      This set has a inverter board on the top right corner. This inverter (or the tubes, I don't really know) buzzes very loudly during the second that the BL stays ON. I have posted a video, turn your volume UP!

      I have checked voltages at the PS
      All normal voltages...
