    magnavox 37mf337B/37 wont power on

    The transformer on the power supply board of my magnavox 37mf337B/37 is making a chirping sound. There are 4 bad capacitors and two charred diodes under the transformer. the numbers on the board beside the two bad diodes are ZD906 and D906. I don't know the part name or number for those two diodes to order replacements. Any help is appreciated.

      hard to say without the exact PSU part number. However SJ is having repair kits for these available.

          How about the Pictures of the whole board?

          You should remove the diode and clean the off the glue so you can read the P/N on the diodes.

              What Zener Diodes on a Linear Power Supply
              by caspian
              Dear members,

              I have a linear variable power supply with unknown brand name that I used for voltage injection.
              Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
              In addition, I discovered that its zener diodes are defective.
              I can replace the burned transistors.
              But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
              Therefore, I cannot replace the zener diodes.
              I do not want to test the zener diodes in a test circuit to discover their model or value.
              no schematics are available...

              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...

              Asus Probook P5440UF-XB74 power issue
              by GLISIT
              Hi all,

              TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


              I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

              A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
              by sam_sam_sam
              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
