    Tc-50ps14

    This tv only has image only top six inches across the screen. And sound theough all outputs. Video stays the same only top 6 inches of screen.
    Don't know what to change. One tech say buffer on z sus since there is image that the buffers must not be letting voltage or image they do to bad ic on buffer. I'm not sure how to check voltages or where to find schematic. Can see one pls send advice will post pictures later. Pls help just getting started and have fixed about 100 sets so far. But need help Testing at component level. Can some one teach me... Thanks Jamie

      Will need a photo to see what we're dealing with. unusual only top 6 inches. does the bottom part seem like the panel is on but no image? may be worth getting into serv tool and try some test patterns in case it's an A board issue

          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....
