    Sony Bravia KDL46XBR2 Issues

    I picked up this TV for free the other week from someone who was looking to get rid of it as it "didn't work" anymore. They said that one day the TV stopped displaying an image but still had sound.

    After receiving the TV, I removed the back panel and cleaned out any dust. I tested the TV using a Fire Stick as the input and the TV was turning on but not displaying anything. Then the TV clicked and restarted itself and suddenly it was functioning (it was displaying static as the input was on the antenna input).

    The TV continued to function for approximately a week and then it stopped displaying an image again. Any ideas what would be causing this sporadic behavior?

    Other things that may be of note:
    - When turning on, the Sony logo and green power indicator both light up, then there's a click and they flick off for a split-second and then back on again.
    - The remote still works for controlling the TV, but the TV will not factory reset. After holding up on the remote and then hitting the power button on the TV, it doesn't start back up as it says it should in the manual.

    1) We need good clear pictures of the boards and how all the boards are connected together.
    2) You will have to do some Voltage testing so I hope you will have proper tools.
    3) We do not have the TV in front of us to look at so the more details you provide the more helps and correct information you will receive.

      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...

      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!...

      Sony XBR-49X800G networking issues
      by HarryZ
      Aloha. First post here, hope I can find someone to assist me.

      I have a Sony XBR49X800G with streaming issues. The issue mostly occurs watching sporting events (basketball and football). The picture will sometimes get pixelated, sometimes freeze for a few seconds while the audio continues, sometimes it's jerky. In other words, you get a headache watching the TV.

      My ISP provides 500 Mb service and I have verified that I have at least 500 Mb on ethernet, and something over 300Mb on WiFi. I installed Analiti on the TV (it's an Android TV) and I get ~ 70 Mb on both WiFi...
