Update , have changed IO board and still no sound/setup or calibration buttons

Also now during boot up the machine appears to stall on the touchscreen controller initialisation , it works through the various speeds and settings, when the game boots now there’s no touchscreen controls.

Not sure how changing an IO board disrupts the touchscreen controller :(

Eliminate the riser for testing purposes.  I doubt you have 2 bad ioboards. My bet is the contacts still aren't clean

I spent an hour yesterday troubleshooting a Maxx and it was the same issue for me. Dirty contacts

Don't know what happened to your touchscreen. Make sure there's a green light on the controller and it's plugged into power and serial

Thanks,

As its a wet and miserable day here in the UK, I have stripped down and rebuilt the maxx, replacing its PSU at the same time.

I think the monitor has failed now, as I briefly see the BIOS Post test screen then it fades out. The monitor would probably be the hardest bit to replace?

No sound from the machine after cleaning and brushing the contacts and IOboard. Am I correct in that the speaker connector pin connects to the right hand side of the IO board?

To elimate the monitor I am going to find a VGA cable and connect it to an alternative screen.

Junk that damn thing and get a Force or Ion.

I can respect your diligence but it's time to put a fork in this thing
