Same here... I have a standalone Yamakasi monitor that gave out (still lasted 7 years though for the fraction of the price of Apple's cinema display). There seems to be boards for all the other versions of the LM2701Q1 series! I have been searching off and on for a month, and like you, have been reading into monitor display tech to see if there is some other generic board I could use, but haven't found anything with confidence that would work. Monitor control boards is such an esoteric subject. I don't know where to go for asking questions. If only there was someway to ask LG for a board!? So frustrating. The only google hit that I found is this no longer available board: https://www.aliexpress.com/item/32879208195.html
