When you said 'Pinball Wizard' i thought you meant the micro had gone. This actually looks hilarious as the display lights flash like a disco rig, reminiscent of a pinball or fruit machine!!
The first thing i would check is the powerlink cables. Have you moved the unit at all? Have you had new carpets fitted (carpet fitters have knives and other rough equipment!), or have you moved the speakers?
Do you have any other equipment with powerlink outputs you could try the speakers on?
If you need any Mk2 Powerlink Cables to test, i can post you some - just PM me your address.
