    Re: Westinghouse LD-4695 T-Con Mainboard Mismatch?

    Just to put a bookend on this. I found a mainboard 60.EB41M.0SA. Installed it. TV works as it should. There are 2 main boards for these TVs. Make sure you get the correct one. Thanks to everybody who helped, it was appreciated!

        TCL 50S535 bad tcon or panel issue?
        by x_orange90_x
        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...

        General Questions on the Relationship Between Mainboard, TCON and Panel
        by mmartell
        My goal here is to be able to use boards on hand to swap into faulty sets when the faulty board is not obvious.

        I will start by asking what is the format of the output from the mainboard and is it generic in any way or does it vary by manufacturer and/or model ?

        And as far as I know a tcon and panel must be a matching pair because the timing of the signals and the voltages required to drive the panel are specific to the panel itself. (That may be a blanket statement that isn't true in some cases where the panel creates its own sub-voltages on its panel boards?)...

        Driving a Sharp TCON/panel with a universal main board
        by advant
        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...

        Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
        by Daren87
        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...

        un60j620dafxza - Samsung No Display Problem
        by stylishconsultant
        Hi All,

        Need help.

        I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

        So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
        problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
        might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....
