PX 870 intermittent startup issue

[Will H]

I have a Casio PX870 that’s having an intermittent startup issue. About half the time when powered on it starts up fine, the lights flash in sequence, everything looks normal, and we get sound from the keys. The other half of the time when started up the lights don’t finish their sequence and it seems to get hung. Keys don’t play, random light is on on the control panel (can be any of them, or none), and it won’t power off except by unplugging it. 
 

Hope these video links work. Here’s the normal startup: https://share.icloud.com/photos/0abrTaolpwY7kRfs86ro2dXNw

Do you have anything plugged into the USB ports?  Unfortunately it may need repairs by a technician.  This is something we have not seen happen before.  It could be as simple as a faulty power supply, or complex like a main board issue.

Nothing’s plugged into usb. Any advice on finding a technician? According to Casio the nearest is an hour away, and I live in a decent sized metro area 😕

It's not necessary to use a Casio authorized service location unless you're looking to claim warranty repairs.  You could likely find any local electronics repair tech to help otherwise.
