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?

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

Re: Sony KDL-46Z4100 another TCON problem?
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... -
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... -
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... -
This TV was showing a fine image and pulsing with a partial double image (offset vertically) every few seconds. I taped 8 clock pins on one ribbon cable from the Tcon to the panel. It stopped the double image, but some pulsing in intensity was still visible. I then taped another 8 clock pins on the same ribbon cable and the image is now ‘fixed’. Although I understand this results in some loss of resolution, presumably because the clock signal degrades as it passes horizontally across the screen.
I am wondering - do these symptoms and ‘fix’ mean that it’s a Tcon fault or... -
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 ?...
