    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....

    Repair attempt Philips 55OLED804/12
    by Sharpa
    Hello,

    I bought a SH Philips 55OLED804/12 TV with known defect in an attempt to repair it for personal use.

    The symptoms when bought: Philips logo appears then tv turns off

    Things tried so far:

    1. Powering it on: Philips logo shows on the screen, sometimes with some minor artefacts then shuts down. Red status led flickers rapidly into two batches then repeats
    2. Put it in recovery mode by pressing joystick down then plugging it to mains: The tv shows the logo then shows the android animation along with some minor artefacts on the screen...
