I just picked up a dedicated MK1 with the factory 25" inch Wells Gardner 25K7197 monitor. When I tested it out at the previous owner's house it ran great, then when I plugged it in at home it didn't. I mast have rattled a solder loose on the ride home.
Anyway, I swapped it out with another monitor and I don't want to bother trying to diagnose/fix it.
Shoot me an offer.
THANKS!
