Oh dear this year is not starting out well. I shut off my Mac Pro for a couple of hours this morning and when I tried to start it the 23"Apple ACD wouldn't start. The light doesn't come on and when I press the monitor start button I get a brief blink (sometimes or nothing). I tried zapping the PRAM and after many restarts no progress. My basic thought is that the Power Supply is dead. A new one would set me back about £125 or I could go for an Acer 27" monitor for about £263. The 23" ACD is about 2 months out of warranty, I had trouble with the previous one and had it replaced last year so I'm not terribly keen on the beast. Should I get a new power supply or a new monitor? Advice would be appreciated.
