    Sony KD-55AG9 TCON?

    Hi,

    I have this problem with my Sony 55' AG9.
    It flashes 4x.
    I have found the service manual, and seems it is the TCON.

    Before I buy a TCON can someone check the vid?

    Thanks in advance!

        open it and post photos tp all boards separately and one to the whole back together

        on the T-CON you have EVDD >22V,,, just disconnect it and see if the tv will complete boot ( screen will remain black) yours sign TV booted and work the audio optic port on main boards will lit red color and remain on

            Post the video from YouTube Link so we don't have to download potentially sketchy files.

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
              by iglitare
              Hi,

              i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
              Backlight seems to work, Sound (Setup menu after reset) works.
              If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
              Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
              With my small knowledge i would think at least the cables are good.

              Can this happen because of a bad tcon board?
              Or is it always a bad/shorted...

              LG 82UN8570AUD ~ TCON or PANEL?
              by kca
              Hello all ~

              Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

              When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

              I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

              Sony KD-55X9000F TCON Issue
              by thelankanguy
              The TV shows a black screen with no image.
              TCON ribbon connectors were disconnected individually for image and there was no half image even.
              Later both ribbons were disconnected and TCON voltages were tested.
              12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
              There is also a short to ground in this circled inductor.
              Is this a TCON issue or something else ?...

              Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
              by odie34
              I am a hobbyist (not a professional) so please be gentle...

              I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

              I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...
