    HP CPTOH-0603 Sustain Failure?

    Hi I am trying to trouble these TV's, I have 2 of them. Does this look like a sustain/buffer fail or just a sustain. I cannot remember exactly what sustain board is in them right now but I do know they are prone to failure and are the exact boards that are known to blow out in the 50" Vizio plasma PHDTV10A-Not sure if thats the model number or not.

    I was just hoping that someone might be able to tell me if they have seen this type of failure before as I have not.

    Thanks again!

      Buffer board, definitely the buffer board.

      Sustains only light up the screen, can't cause this.

          I did pull the buffers and found a couple blown fets on both bottom buffers. Swapped some from a good upper board from one so I have one working TV and waiting on a couple fets for the other. I just have to keep remembering that it's not the same scenario as with the Samsung boards and it's not always the Y-Sus. Thank you very much for your response!

              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

              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....

              Schematic or datasheet for Plasma TV buffer chip
              by Yanleb
              Hi all,

              I'm interested in understanding how a buffer board chip is working. I know there's about 90 outputs per chip to the plasma panel, but I'm more interested to know about the input pins. I guess that some of them are address pins, but I want to know more.

              So far I've found nothing at all. I haven't found any datasheet about the various buffer chips, and I haven't found any schematic for the buffer board using them (Y Buffer Board in Samsung's terminology).

              Any information will make me happy. It can be from any buffer chip or plasma TV manufacturer....

              Pioneer Plasma 111FD To Solder or Not to Solder.
              by pixelcap
              Hello out there in Badcap land.

              I have a Pioneer plasma that gave me the dreaded 8 red blink and shutdown, I have been trying to trace the failure points. On my last inspection while replacing a Y Sustain Board I noticed on the original and replacement board some missing solder, the points of connection
              are from the Digital Address Board and the Buffer Boards. I have included the pictures, should I resolder these points or are they unsoldered intentionally? Any help would be much appreciated.

              Thank you
