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 70โ 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, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?07-21-2023, 09:05 AM
