S2000 Button Lights dont work

[sbsgroup]

I have a new white ice three reel s2000 the buttons work but don't light up.  They all work fine the game plays like it is suppose to but the buttons just don't light any ideas?  Could it be something is bad on the MPU it is an enhanced board.

Why don't you start by checking the light bulbs ??

I replaced the button bulbs with working bulbs off another machine, still no luck.

ballast maybe? or powersupply is going bad..

Could be the MPU but I think I'd look at the IO card first and also make sure nothings been left only half plugged in

[cowboygames]

If I'm not mistaken, the only wiring from the door other than the IO card harness is the BV faceplate lighting and the door optics, so the button light wiring must run through the IO card

Thanks Ill have a look tomorrow and see if something is loose.  Thanks again for the help.

If the button bulbs are LED remove one, rotate it 1/2 turn and reinstall

I ran into this once.  I can't explain why but replacing the reel glass display panel solved the problem.

Thanks,  I will also explore this as a possible cause.  I am going to change enhanced boards and see what effect this has.

if the game and all other lighting are normal  you could have several things to check.   since all the button lamps will not work there is one thing common to them. +13 vdc is applied to one side of all the lamps, coming from the door I/O.  then the door I/O will provide a ground  to lite each lamp  as told by the cpu via the door I/O. 

the 13vdc wire is the red wire going to all the lamps, you should be able to measure it from the lamp post to any machine metal part.

Hope this helps
