New Member - Need Help in Identifying My Pachinko Machine and Solving a Problem

[Ron Ford]

Hi - I am a new member of this forum, although I have owned both a Pachinko and a Pachislo machine for many years. I have the Pachinko machine pictured below, and am having an issue with the video screen in the center of the playfield "rolling". For those of you who remember when tube TVs had a 'vertical hold' adjustment, it appears to need something like that. The machine works perfectly well other than that.

Any information on identifying model, age, etc. of the machine, and any suggestions for solving the issue with the screen, will be greatly appreciated!

Thanks,

Ron
