Hi guys- does this look like a bad t-con board to you? It weird that it is only 1/4 the screen and not 1/2. I don't want to order the board without you guys looking at it since I'm a novice.

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
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 everyone. [Sorry for the long, detailed post in advance].
I have a Sharp LC-52E77UN which randomly shuts down--could be within 15 minutes, could be 40 minutes, over 1 hour, it's unpredictable. From reading the service manual, I was able to get into service mode (where the K is displayed), and found the following error flag toggled: "04 Initial Communication Error 4 -- Error reason: To the communication setting reception," which, from contacting an eBay TV repair store, I was told is caused NOT by a bad TCON (which was my first guess), but rather the motherboard.... -
Wondering if anyone has addressed an issue with the SHARP 70” LC-70UD27U having thin black and white lines running from left to right horizontally on the screen. I snagged this TV set from a neighbor since I have been successful in repairing numerous other TVs. I assume this probably happens to other TV sets and may have been addressed in another thread. If so please point me in the right direction.
What I have tried so far.
I have tested all HDMI inputs with the same results.
I have checked for firmware updates.
I have reset to factory settings.
I have removed... -
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...
