    Sharp RDENCA369WJQZ (Delta DPS-343AP A, Rev 01F) Power Supply Unit Schematic Needed

    Hi Folks,

    I'm filling some downtime trying to resurrect a Sharp LC60E88UN. It was easy to find the service manual online, but it doesn't contain the schematic for the power board (Sharp RDENCA369WJQZ / Delta DPS-343AP A, Rev 01F) Power Supply Unit. I've looked everywhere I can think of using both part numbers and can't find it. Can someonee with access to this document share it?

    Symptoms - no audio/video/backlight and blink code: 1 x power light followed by 1 x power and OPC lights together. Seems like a Lamp Error, but I'd like to check power supply components and voltages while I have it apart in case the OPC code is not related to the 1 x power code . . . The service manual doesn't list any OPC codes related to the 1 x power code.

    Thanks for any help you can provide

    You have to count the blinks separately. So 2x power and 1x opc. What does the service manual say? If lamp error, then bad backlights.

      Please attach good clear pictures of the whole backside pf the TV showing all the boards.
      What Voltage testing have you done on the power supply board connectors?
      You may also want to read some of the threads her since it is related to the same power supply board: https://www.badcaps.net/forum/search...rchid=17059523

        Thread linked from budm shows 2xpower as power supply error and 1xopc is 15VDET error and was repaired with shopjimmy repair kit.

          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...

          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...

          Modification to a ZD-987 desoldering/soldering station using a external switching power supply
          by sam_sam_sam
          I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

          I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

          >>> Troubleshooting Delta Power MAX 500ATX ATX power supply
          by dragon3x
          Hi, this is for troubleshooting and, hopefully, repairing a Delta Power psu
          that is still quite new, as it worked OK for some months until it failed.
          At the time I was not into power supply electronics; it was put
          aside and a new power supply installed inside the computer. Also at the time
          power supplies were half the price of today's.

          On the PCB there are a D339 and 7500B chips.

          I have found that schematics with these 2 chips (see included file).
          Does it represent the actual circuit of the MAX-500ATX, I cannot tell.

          Some measurements,...

          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...
