          Take the back of the TV and there will be two cables going from the tcon to the panel that connects to the screen. Disconnect one at a time and power on the TV. See if there is a working picture on one of the sides that isn't black.

              So your getting no images on screen or is that test screen?

                      im hoping this hasnt got a bad panel as i picked this tv up for free! or could even do one of those temporary tab bonding fixes if it has indeed got a bad panel!

                          if you have a good picture with one side disconnected and a messed up picture when you do the other half, then unfortunately you have a bad panel.

                          if you can correct the picture by squeezing the bezel or twisting it slightly, then you may be able to do a successful tab patch. outcome of patching tabs is various. i have had some fail as the temp rises and some are still going years later.

                              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 KD-55AG9 TCON?
                              by bbrain
                              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!...

                              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,...

                              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...
