KTN-2001 screen from hell
« on: October 09, 2010, 01:20:51 pm »
So I bought a KTN-2001 for a cent cab from arcadeshop.com but it's now strobing and rolling white vertically. I've recapped it,
rebuilt the AR2 board, rebuilt the power bricked, swapped centipede PCBS to no avail. Any suggestions?

Here's two videos of it in action:
