I have been asked to take a quick look at my pals "broken" iMac G5. This iMac.. The problem.. The mac is running phsyically, But the screen is black, As if it were not on.. Being a long mac user, I immediately reached for my torch, Shined it onto the screen annd immediately diagnosed the problem, A bust Power Backlight Inverter. This is what i need Just wandering how I would go about obtaining one of these, I have phoned Apple Support, They reffered me to a nearby Retailer, But no luck they have none and do not recognise the item. Thankyou.
