Title: Mav500/MK5 Blinking Button Lights - Popping Sounds
Post by: Ken on September 16, 2017, 07:22:29 AM

When cash is inserted the bottom row of buttons flash and at the same time it sounds like a popping noise coming through the speakers. The four center buttons on the top don't light but work/light up in diagnostic mode.

Any suggestions on what to check?

Thanks,
Ken

Check your IO Driver Board. It may be ajared or its faulty.

Thanks - I am trying to find the correct I/O board part number. Has the one for the round (blue) button in it right now.

This should be the one you need...
This is the one I used with the non-led button deck.
Its the same one used in a MK5 machine

I have tried 3 different types of I/O boards with the same result.
