Possibly the strangest problem I've ever encountered. I picked up a dedicated Sega/Sammy Zombie Raid cabinet. It originally had a WGK71XX monitor which someone had raided the chassis off of. No problem, I got a few other monitors on my shelf. The first one I drop in is actually one of my frankenstein specials, a Samsung TV tube and a modified Wei-Ya 825HR. Fire it up and the pic on the screen looks to be having a vertical hold problem, but I *know* this monitor is solid. High voltage pitch sounds a tad high. So I swap the pcb for a Konami Lethal Enforcers which shows up fine, no problems. Tested the power supply, good power, disconnected the solenoid driver for the guns, removed a chassis ground to common ground jumper on the PS also- no fix. What is going on??
So then, I put the Zombie Raid into my dedicated Lethal Enforcers cab which also has a WGK71XX on it with original chassis, works fine, pic looks great, no problems. Easy, I will just swap the WG monitor from the Lethal Enforcers into the Zombie Raid cab. Did that, put Zombie Raid pcb in, fire it up- SAME PROBLEM! Sooo weird...
Lets make this more weird- I not only have one copy of Zombie Raid, I have 3 pcbs to play with. All 3 do the same thing. I then went around trying it on various games, several WG monitors, no issue, another Wei-Ya, no problem, then finally another Wei-Ya 825HR which had the problem again in another cab. So like 2 of some 6 or 7 monitors I try it on had this issue, one of which only developed it when being put into the ZR cab. I'm sure if i pulled that monitor out it would work again in the Lethal Enforcers. I really wanna say this is related to the ZR cab, but what could it be?
So this is sorta a "gotcha" problem, i've never seen anything like it in my entire collecting experience. I'm hoping someone has this game and has seen this problem before.
EDIT - Could this be some sorta strange sync problem for this game only? The only thing not moving from the Lethal Enforcers to ZR was the monitor signal connector. I noticed it had a jumper between monitor sync and ground... hrmmm
