    LG 55UN6955ZUF. Help

    Hi
    I recently acquired an LG55 UN6955ZUF
    When I cycle it on it has backlights and audio.
    No video just the light blue hue of the backlights.
    I've replaced the main board hoping it would take care of the problem but, same outcome.
    I've started taking some reading from the buffer strips on the panel itself but I'm not sure what the reading should be.
    Here's the current readings

    LEFT SIDE BUFFER
    VCC33. 3.35 VDC
    CLK 70 ohms
    DI 130 ohms
    GND. gnd
    CS 3.27 VDC
    DO. open
    WP. OPEN

    RIGHT SIDE BUFFER
    VCC33. Open
    SCL. Open
    SDA open
    GND GND

    Has anyone had issues like this.
    The tv is only around 4 months old

    Thanks in advance

      Unplug the ribbons and see what you have in the picture.

          Hi,
          I have tried unplugging each side individually.
          Made no difference.
          Same result .No video

          Thanks

              A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

              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....

              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

              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....

              Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
              by max789
              Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

              I made the following tests:
              1. Disconnected the main board from Power Board = backlight works.
              2. Connected the main board and disconnected the T-Con = backlights does not work.

              So I ordered a main board from Ebay also BN41-02156A but from...

              VIZIO M557-G0: Backlights or ???
              by bpcannan
              'Morning,
              I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.

              Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.

              I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.

              I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate...
