2 turns off after a half hour and must be disconnected and reconnected
I thinking about buying this non functioning apple cinema display and fixing it my self, This is what the seller says in the description "Works perfectly EXCEPT it turns off after a half hour and must be disconnected and reconnected. This is a known failure that according to blog forums is due to the posterior cable that needs to be replaced. A repair shop quoted me $400 to replace it but a handy person could probably do it themselves. " Do you think this is fixable, and you really think that its the all in one cable? I would like an expert opinion before I consider trying to fix this.
