lcd panel driver board repair in stock

A couple years ago, I managed to extend the life of my LCD TV using a very basic trick. I thought the main board was fried, but ironically, baking it fixed it :-D.

Anyway, now the mainboard is fried for good (after being baked 4 times), and I want to find a universal board, but I have no idea how to find one that matches my LCD panel. The panel model is LC420WUH (SC)(M1). Back then @oldturkey03 had kindly helped and found the specs sheet for the panel: LC420WUH-SCM1-LG.pdf .

When looking for generic boards online, most of them need to be connected to a T-CON board, but this particular TV doesn’t have a T-CON. It seems to be embedded in the main board.

So my question is quite simple: how do I go about finding a generic board that matches the LCD panel? I’ve spent hours looking for it using search engines, online shops (from big ones to small ones) and other resources, but no luck so far.
