    Sony Bravia KDL-46V4100

    So a friend dropped off this tv for me to look at and the first thing i did was came to this site. It recommended to check the fuses and LVDS from the main board to t-con. All of the fuses i seen had good continuity. I reseated the LVDS on both ends.

    So i hooked up the tv and it ran without any issues for for three straight days. I even unplugged and plugged it back in at least ten times to test it. You know what happens when he gets it home right? Less than two hours later he gets back to be saying the tv has gone into standby mode and will only come out of that mode after it "cools down". He said the kids had the volume up to 88 when it happened. It came on for 10 minutes after it "cooled down" and went out again.

    This situation kind of has me stumped. Maybe its a weak power supply and cant handle the speaker wattage or when it runs warm there's a heat protector on it that puts it in standby. I dont know. Any help?

    It may well be a power supply problem, an inverter board issue or a failing CCFL lamp.
    Without any voltage measurements it would be difficult to guess at this stage.
    Willing to help but I'm no expert.

      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!...
