Hi,

Firstly I am extremely sorry if I have posted this in the wrong forum.
I am looking to identify the following cable that comes from my LG TM120 control board for my HD TV. The version of the control board is V14.
The board has two ribbons coming in and then the cable below coming out. Can anyone help identify this port/cable as I would like to convert to an HDMI port.
The black end is the one that goes into our board. And the silver the one that plugs into the control board from the TV.
Images attached.

Regards,

Steve

Steve, big ask. You'd really need the schematic (circuit diagram) of the TV to do this. And they are almost impossible to get these days, if a TV goes wrong it gets chucked, not fixed....If it is an HDMI port already, you could maybe do something, If it is something else, no way.All those twisted pairs indicate that it's something with multiple data channels. Maybe....If you're really keen you could look up the datasheets for the chips used on the board, and poke around with a meter to get an idea which wire goes where. But by the looks of that board, it would be a huge job.

Thanks David, it is prt of a digital advertising screen the panel works well but goes into an Android board. I was hoping to convert to a hdmi so I could use a different input.
Could I try converting it to HDMI (on the chance that is what it is)?Steve

Hi Steve-What inputs does the TV have? What is the model number of the TV?. Chances are slim, but I may be able to find some information.-Rick

Hi sorry for the delay, I do not know the model of the TV as it oa only the panel in the back of the unit. I have taken the Android board off and the pattern on the bottom of the board is like the picture. Does this help? I am not sure if the picture will show clear

I have taken another photo of the Android board this cable goes into. Hoping looking this side may help? I have also made a table of the colour cable going into each of those pins.

Just found this image on the web, it look like it is a Dual LVDS output

Topic summary

The discussion centers on identifying a specific cable connected to an LG TM120 V14 control board used in an HD TV panel, with the goal of converting the output to HDMI. The cable in question has a black end connecting to the board and a silver end connecting to the TV panel. Due to the lack of a schematic and the complexity of the board, direct conversion to HDMI is challenging. The cable appears to carry multiple twisted pairs, suggesting it transmits multiple data channels. The panel is part of a digital advertising screen currently interfaced with an Android board. Attempts to identify the cable include sharing images and pinout color coding. An image found online suggests the cable is a Dual LVDS (Low-Voltage Differential Signaling) output, which is commonly used for high-speed video data transmission between control boards and display panels. Converting Dual LVDS signals directly to HDMI would require specialized hardware or a converter board.
