Did you verify that you have the DCV on both end of the fuse on the TCon board to make sure it has Voltage to run the Tcon?Never stop learning

Re: Sharp LC32-SH340SE/V 17MB60-4
How many ribbon cables foes it have between TCon and the LCD panel, two? If there are two, then try having one connected at a time to see what you will get on the screen.Never stop learning

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... -
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...Today, 02:09 AM -
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.... -
Hi there,
My son's gaming monitor started having rolling image (vertical roll - See Video) similar to vertical sync issue, or T-CON problems in TVs. Has anyone see this? is it fixable or a throw away?
I haven't even opened it up yet. Does it have a T-CON? Help is appreciated.
It does this even with the monitor not connected to a computer / graphics card.... -
Hello all. 3 years back, with your help, I replaced the LEDs on this TV. It's been working great. Yesterday, I turned it on (garage TV), and it has blurred horiz / vert lines as you see in photos. Definitely no physical hit or damage. Top 1/6th of the screen is perfect. Could it be main / TCON board? No tabs to cut on this model. Thank you...
