No - all the sound etc. seems fine, just those sections of the bulbs. I'm a bit of a noob when it comes to fixing etc. What do I need to look at replacing/fixing? Really appreciate your help.DONT TURN IT ON your risking a fire hazard check all connections to the motherboard, it might be the mux unit thats at fault and needs replacing, have you noticed any other changes within the machine, poor sound quality? machine taking ages to come on, that sort of stuff?
