I picked up one of the original 21" ADC cinema displays for the G4 for a reasonable cost (nothing) and it appears that the bottom backlight tube is a little on the weak side (takes a minute or two to get fully bright) and the one on the top does not light up at all. The power light blinks a fault code which eludes me at the moment.

I'm ware that the inverters on the smaller 17" are very well known for a similar issue however I'm not sure just how similar my issue is to the 17" model, or if the DIY repair steps are similar.

Has anyone else had to go through this and can explain what's up before I split the monitor open and start poking around at the inverter board?
