    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-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,...

                          Sony KD-65x8500b - bad Tcon or panel?
                          by rimwall
                          Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
                          a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
                          b) the Tcon board is malfunctioning,...

                          TCL 50S535 bad tcon or panel issue?
                          by x_orange90_x
                          Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...
