    YSUS board repair - Panasonic TV

    Hi guys,

    I have recently gotten a plasma TV with a shorted SC board. Someone had been working on this before. They removed some of the mosfets, a gate driver and a couple of other components, so I'm not going to be replacing mosfets until I know there's nothing wrong with it.

    I coulndt find a technical information online explaining what exactly is the SC/YSUS board function. A similar question placed earlier on this forum Y Sustain Board pointed to an external link, but that is only for troubleshooting, it doesnt explain what the thing function is.

    This appears to be some sort a switch mode converter to power the buffers. If this is the case, I could remove the mosfets, plug in an external supply for the HV output to the buffers and see how the mosfet drive is working to continue my repair.

    Any hints on this? Thanks

          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.

          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...

          Panasonic TC-P54VT25 No image. A or D board?
          by canadaboy25
          I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

          The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

          I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

          TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
          by howardc64
          All left and right refers to looking from rear of TV (or looking from front with TV upside down)
          • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
          • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

          Hi everyone!
          I happened several times, in the search for help from the web, to consult this very interesting forum.
          So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

          Having said that I come to the gist of my post on the forum as the title suggests.
          For my passion for technology I'm now collecting several...
