The TV displays in what looks like inverted colors with a red tint. Im guessing this is a tcon board but want to run it by you guys in case I can swap a chip for cheap. I get 12V on both sides of the fuse on the tcon board

I believe the panel model number is either
E249AZNKW3BYNN
or
C39C6434PDZZ-ZS1100
or
T420HW04
