The problem you have described here has nothing to do with t-con board it self. You have damaged LVDS flex cable. But first to answer your question - yes , you can swap T-Con board, but you need to get it with same modification/software version . As lcd screens has been made in different factories, has different COG (Chip-On-Glass) configurations and so on… To do that - there is a QR code sticker with letters/numbers on it. It describes what software setup has been installed on t-con board. Usually in our repair shop - we salvage them from broken screens .
