Title: Monitor not working
Post by: Paullatham on September 18, 2020, 08:25:59 PM

I have a Sigma Video Poker that has a line across the center of the Monitor. When it was put into storage a few years back it worked fine. Now that it was moved to a new location I have this problem. Any help would be greatly appreciated. Says its a Sigma Poker Up, Model B-12
Thanks

Looks like the vertical driver chip has failed or, and this happens often, some traces going to the chip have heated up so much they have opened.

Sorry,  but I'm new to the gaming world. So far I only have the service manual for my seeburg jukebox.
How can I check the Vertical chip?
Thank for the help, it's greatly appreciated.

It is a multi leg chip mounted to a large heatsink on one edge of the monitor board.
Is this a Tatung monitor? What model? I could email you a schematic if so.
PM me.

I'm not the CRT pro, but that looks almost like the set-up switch is on?
