    Image problem on Sony Bravia LCD KLV-37M400A

    Hello guys,

    I have a Sony Bravia LCD TV model KLV-37M400A.

    It started to show strange colours at image, like the 2 images attached. I made a video too. You can see here: http://www.youtube.com/watch?v=15-ilEoqPrQ

    When I turn the TV on, it shows the correct image for just about 1 or 2 seconds. After that this strange colours starts to appear.

    Do you know which part of TV can be broken ? What kind of test should I do to prove this ? I just have a multimeter.

    Thank you very much!

      First try unplugging, cleaning, and replugging the cable and connections going into the Tcon board.

          Sony KD-55XG9505 lines on screen problem
          by Chrissygizmo
          Hello again everyone,

          This is my latest mission, to try getting this Sony tv back to normal working order…

          I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

          Sony HCD-HX80R Amplifier Volume Control Problem
          by crackedprint
          I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.

          I have tried a Cold Reset as per the service manual.

          I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.

          I have looked all the way through the service manual and tried many online...

          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!...
