hi all, was hoping to get some advice on an issue Im having on an "untested" MK1 board I just purchased (yeah im a sucker)
Running this in a working UMK3 cab, The board starts up and gets to the RAM check and then at the U66 chip goes it red. After that the screen turns to fuzz.
have: MK1 Y-Unit Board, Sound Board, Ribbon Cable, Sound power cable, sound pot
same symptoms without sound board attached
Heres a GIF and some screenshots of what is happening:

Should I focus on swapping the RAM chip first (best way to do that)?
Would any NEC d41464c-10 RAM chip work (seems to be quite a few on ebay)?
anything else to be prepared or check for?
Any help would be truly appreciated!
