I sent them an email, but the guy I got the phones from told me he had no luck with the company and thats why he sold them to me. I thought someone here might have a scan of the service manual. Seems like Ernest is the least supported and the least desirable of the bunch.
Help with my Ernest board
I just picked up 2 payphones with the Ernest D3 boards. Seems that both are dead. I need the schematics or service manual for them. I could also use the pinout so I could connect an LCD display to the board.
I've changed the battery on the board, voltage on hook is 48...
It started out with the image folded over and convergence issues. I unplugged the yoke and powered it up for a sec, that messed up whatever makes the monitor sync. Now it will sync with my pc but not the game, but the game will sync with a pc monitor. Still may have a tube issue after the board...
The yoke is solid and the alignment marks are still intact. I checked the resistance of the horiz coil and it read .5 ohms and the vert coil read 5 ohms which I think is about normal.
Any ideas what would make the display shrink to the center and have a convergence problem (see pic)? I bought this machine with this problem so anything is possible.
