Re: Sony KDL-46Z4100 another TCON problem?
Thread hasn't been updated for awhile, time to bring back from the dead
I'm also having trouble with the same tv, KDL-46Z4100. My TV looks exactly like the OP had on their set. I ordered a "used" TCON board from an ebay seller, but there was no change in the picture.
I haven't tested any voltages/resistances, but my standby/power light would not blink either when I turn on/off the tv. What's the likelyhood that I need to try another TCON board?
Thanks in advance!Attached FilesComment

Have you tried the usual one ribbon connection at a time on LCD panel?Did I leave the soldering iron on?Comment

Re: Sony KDL-46Z4100 another TCON problem?
I tried loosening the ribbon cable plugged into the TCON board, there was no change. Picture went black when I removed the cable completely.
Reset the two small ribbon cables at the top, no difference made.Comment

The flat white ribbons? There should be two of them. Try one at a time. These are the ones that go from the tcon into the LCD panel itself.Did I leave the soldering iron on?Comment

Re: Sony KDL-46Z4100 another TCON problem?
Good morning from Greece i have a KV46-EX1 with the same problems(vertical lines)it is seems to be a bad panel but i have done a little experiment.1. i connect the ribbon cables and i saw to big vertical lines on screen right and left 2. i disconnect the ribbon cables and i saw nothing on screen(logical) 3. i connect the left ribbon cable and form the side of the disconnected cable i saw nothing but from the other side i saw a big vertical line. 4. finally i connect the left cable and i disconnected the right.I noticed that i have on the right side white screen with lines and from the left side a big vertical line .maybe is the t-con board and not the panel.... the board is the A1567986A Any help or advise could be usefull Thanks for your answer!!!!Comment

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... -
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 ?... -
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!... -
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,... -
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...
