Hi, I have an older 23" Cinema Display-- the light on the front just started to 'flash' 3 times (2 short, 1 long) which appears to indicate some issue with a backlight? How can I find out what needs to be replaced? The backlight itself, or could it be the inverter board? Is it worth fixing or should I move to a newer display? I'm running a 2009 Mac mini with an adapter... Thanks for any guidance/advice.
