Hello all, could really use some help. Washer (samsung flexwash WV55M9600) went down about two weeks ago and have tried everything. It will power up, but the display is gibberish and the buttons randomly control different things. The top washer start button controls the door lock for the lower washer. If I press power on the top washer, it will say 14 on the panel, but other than that it's all just random lines on the display.

Replaced the upper control board, the control board behind the drum, the inverter board, noise filter is good. I hooked the washer front panel up to the dryer, and it functions fine, so leaning towards it not being a bad display panel? I've checked continuity for the display wiring down to the board behind the drum with nothing to note. At a loss for now, anyone have any ideas? Thanks
