I just bought 2 17" Apple Studio Display monitors at a junk yard for $20 and 1 seems to power up and gets warm but no signal, the other the power led flashes from green to orange. Anybody know of common issues with these or can direct me somewhere before I go and open these up ?? If all else fails any fourms or guide's to monitor hacks and basic opening and how to, this will be my first monitor fix/hack. Anything else reguarding to Apple 17" Studio Display monitor's and possible hack's or fix's...thanx.
