    Lg 50ps6000

    Hi guys,

    I am having an intermittent issue with a LG 50PS6000 plasma screen. The unit starts up fine and runs without issue most of the time. However once it's been on for a while I start to get a vertical red bar going up the screen, it's the width of one of the connectors on the xr buffer board. The image is still there, it's just tinted red, like the other colours have turned off.

    I pulled the ribbon cable off the buffer board and cleaned it with IPA, but the problem has now returned.

    Just looking for any advice on other things I can check, before I go buy another buffer board to try that.

    I'll try and post a picture of the fault later.

    Many thanks,

    Mark

      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....

      Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
      by Asraf Atb
      Hi everyone,

      Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

      Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

      I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

      A2991 Logic Board issue, 20volts 0 amps help!
      by Stephen
      Customer plugged in samsung monitor into the board and used it as a power supply, killed UG800 and UG400. I replaced those two with an exact donor board we had In stock and working, board pulls 5volts and then gets like 2.89 amps on the left side. The singular port is the port that failed. Used a perfectly working chips from donor (board was locked) Now I only get 5volts 0 amps on that power and then 20volts 0 amps on the two left side ports, I checked for DFU and nope nothing, computer not turning on. No shorts present anymore. I am confused as I used the exact components from an identical...
