Supreme board problems

[Mirage_Chaser]

I have a poker progressive sign that is giving me issues. It uses a supreme controller and the controller is constantly freezing and/or rebooting. It started out that it would freeze every once in a while I would just reboot it and the amount would update and it would work for a time.

Then recently it started to freeze all of the time and I would reboot it every once in a while to update the amount and I didn't worry about it. And it would reboot its self occasionally but as that kept the amount more accurate hey all the better.

Now all it does is freeze on $0.00 or reboot.

Anyone have any ideas?

Also I tried to replace it with a cham ii board I had but the display was upside down, is there a way (other then flipping the screen) to right it again?

I noticed the battery is reading 2.5v, which I believe is low (supposed to be 5.5?? Not sure though)? Could that cause my problems? Could I just add a 3.6v battery in series? That may be a silly question but I don't have any 5.5v batteries.

Generally they had a SuperCap at C32,  there was an option of a Battery for jurisdictional reasons but I would be surprised if there was one.  Check the SuperCap, the 7805 and heatsink which get get knocked about, their contacts crack.  Sometimes a 5vdc input problems can be jumped around by feeding 12vdc into J2 from a plug pack, the board ups some 5vdc to 12vdc for the RS485 and 422 comms and it jumps this stage.  Also a good RAM clear helps, power up with the CONFIGURATION switch ON while holding down  the two dimple buttons (FUNCTION , VALUE).

I believe that's just a configuration issue on the CHAMII.  That happened to me and I had the settings wrong.  I would closely inspect all of your settings on the CHAMII.

[ADD] I missed McCackie's advice about a RAM clear.  Good advice!
