    TX-P42C2 4 blinks

    Just fixed this one, so to leave a part list, maybe it will be helpful to someone. Although after so many that this model is out i doubt that someone is still using it

    So, it was a 4 blinker, straight away checked SC2 connector - obvious short.
    Damage was:
    Q661 - RJP63F3 - replaced with the same one
    Q402 - RJP56F4A - installed RJP63F3
    Q421 - 2PG011 - installed 45G128
    Q621 - 45G128 - installed same one
    Q451 - DG501RP - replaced with 45G128
    Q701 - smd code 2D
    IC773 - smd code HA
    Q702 - smd code C3W
    D701 - was open

    16V_F line was shorted, when i replaced damaged components i got consumption of 43mA on 16V_F line
    5V line - operating with 5mA
    15V line - 5mA consumption with injected 15V

    That was all damage, drivers for IGBT's were fine.

      Panasonic P58V11B 8 and 12 blinks error "fix"
      by Biruslapio
      Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

      Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

      Samsung UN50TU8000FXZC shows thin horizontal green line when warm
      by cubytus
      Hi to all,

      I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

      I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

      Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...

      Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
      by Nairolf
      Hello,

      I have a Samsung DM32D display.
      When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

      Here’s what I have tried so far:
      1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
      2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
      3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

      From these tests, I suspect the problem might be on the mainboard. Could anyone...

      Vizio E701i-A3 fixed but now has red vertical line
      by otaku_nut
      Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me. I used Freakaftr8's fix to remove the left driver board to restore picture to a black screen with sound Vizio E701i-A3. After doing so, I now have a large red vertical stripe down the center of the screen. The fix did require getting another t-con board from online, I ordered it before I knew about the mosfit fix for the old t-con board. I have tried cleaning the cable connections to the t-con board. I swapped the cables going from...

      Kogan - KALED65XU9220STB - Blue Vertical Line
      by TrueSword88
      Hi all.

      I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
      The line just happens to coincide with the end of COF and start of the next COF (attached).

      The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.

      Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.


      Hoping to fix...
