      Lemme see...
      ZD1 = 15V zener diode. Make sure you get the same diameter.
      The diode you circled black is a HER107. This diode is ultra fast.

      About Q1: The package is called TO-220F-6L
      I suggest you find the little plastic pieces so we can narrow the part number down more. I can see that it did start with a DM xxxxxx. And I can see an E above that part number. A quick search on Ali revealed this:
      DM0565R / FSDM0565RE
      also a       DM0465R that could fit.

      Check what you find, vs what I came up with.

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          Mitsubishi CNC switching power supply board dead / relay board bad diode failure
          by sam_sam_sam
          I was working on this CNC machine today found no keyboard functioning no control relay powering on
          The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board

          Found shorted diodes on main controller relays there are 3 of them that...

          [HELP] Acer AN515-55 (LA-J871P Rev: 1B) – Board won't power on after GPU investigation – Suspecting Super I/O or PCH

          Hi everyone,

          I'm working on an Acer Nitro 5 unit with the following specs:
          • Motherboard: LA-J871P Rev: 1B
          • Model: Acer AN515-55-59MT
          • S/N: NHQ7JAL00403906A973400
          • SNID: 03902728734
          Initial Issue


          The laptop initially presented graphic issues and driver failure (Code 43) for the GPU.

          After preventive maintenance (cleaning, thermal paste, etc.), it powered on normally. We disassembled it again to inspect the GPU, reassembled...

          by Dani_2024
          Hi and thanks in advance for any input you might provide!
          I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
          Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

          Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

          Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
          by sam_sam_sam
          I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

          This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

          After all of...
