    bravia kdl46s4100 last ditch effort

    so i picked up a 46 inch sony bravia lcd TV from a thrift store about a month and a half ago. worked perfectly in store, but at home was experiencing what I now have concluded were tab bonding issues (lower right half of screen with horizontal lines that would go away as you flexed the bezel).
    thought i'd open it up to try and do a tab pressure fix, but in the process, tore a ribbon cable at the top of the lcd panel, connecting to the top "left" circuit board. (see picture)
    after poking around, though i'd try to use a conductive pen and an exacto knife to reconnect the traces. thought i'd got it all connected, multimeter giving me continuity, only to find my shotty job shorted the traces and ended up burning the ribbon cables.

    so, is there any salvation to be had here? as i understand, the ribbon cables i tore can't be replaced since they're bonded to the lcd panel in a fashion a home tinkerer can't replicate. should i just part it out on craigslist? solder wires between traces?

    I'd say you have to know when to move on. Unrepairable. It's time to move on.

      Sony Bravia KDL-40V2500 that will not power on
      by PopsCaps
      I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
      I do not hear any sound and I cannot see any backlight.
      I have tried disconnecting every cable on each board one at a time to see if anything changes.
      The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
      My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

      Sony bravia kdl-43w755c - boot loop
      by justin35
      Hello,
      i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
      from what i read online it looks to be an emmc issue…
      i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
      i took out the board and say an samsung 16gb emmc
      i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
      i could try to put one instead of the 16gb one, but will it work?
      where do i get the software from?
      any help will be much appreciated!...

      advices for repairing Sony Bravia 32EX600 after lightning strike
      by pbig
      hi everyone,
      my parents in law have seen their Bravia Sony LED 32EX600 TV set stop after a lightning strike. After being plugged to mains, it shows nothing no power LED on bottom left shines.
      On the power PCB (GE3b, attached pic), I chacked the fuses and the only roasted one is R6536 : 0.47 ohms, 1/2W. After replacing it, I made some voltage measurement with ref to the chassis :
      - the 450V/150uF capacitor voltage when plugged is normal at 394V
      - from connector CN6150 (15 poles)
      STBY normal 3.3V -> I shunted it to 3 (POWER ON) and 11 (BL ON) and unplugged...
