what would cause you not to be able to get into settings/menus? replaced batteries, tech repl several related ICs....could it be bad roms?

Are your coin door switches hooked up? Also is your 4 pin connector on the lower left side of your cpu board plugged in? Bottom most left side. There is also a 4 pin ground connector. If you plug it in wrong, your advance switch goes grazy (no damage threat).
 
Switches

I had an intermittent failure with my switches. Tech friend told me to spray wd-40 on them. Have worked without trouble ever since then.

switches work all the way to the IC cause my tech thought that also! only thing i can figure is a board problem. Or, maybe the switches aren't giving enough on/off signal??? idk but it does toggle through plug on pcb and thru the IC that its suppose to.

One thing I forgot to ask is it just the 3 door switches?
