Video Game Repair/Error


I have a NBA arcade machine I want to no why this happened and how to fix it,,,,

This messag pops up on the screen

CMOS invalid fac settings restored errors detected any button to continue

Hi Jasper,

This error message means that the battery that holds the values in the CMOS is dead and needs to be replaced. If i recall correctly, it's a CR2032 battery, and is very inexpensive. If you look at the board, it's the coin-sized battery under the clip.

Hope this helps!

I can answer questions regarding coin-operated arcade game questions down to the logic board. Error codes, erratic operation, dead boards, I can help with them all. I can help with video monitors on a very limited and basic level only.


I have spent nearly 20 years as an avid arcade collector, and spent nearly 10 of those years as the lead tech for a large arcade operator, doing work for manufacturers and other coin-operated amusement companies around the globe. I maintain a good sized collection of arcade games, as well as a large inventory of spare parts for a wide range of arcade machines.
