    My problem is similar, but I have a 22" Apple Cinema Display. The older generation one, I think it was the 2nd one, and has the clear plastic with white borders. Anyhow, my monitor seems pretty dim and it takes a while to get brighter, which is still not as bright as my newer monitors. The colors are not as right, vibrant, and bright as I think they should be... I have compared the monitor to another same, but smaller monitor and it definitely darker, but not like dark or impossible to see, it just seems dimmer than the rest. Does this need new bulbs or one of those inverter boards replaced? ANy info would be appreciated.

Double check you power cord and try switching plugs.

sounds like its not getting enough power or a CCFL is going or is out and you need to get it serviced if thats the case.


Do not attempt to repair this your self Monitors usally have there own power supply built ind can store massive amounts of energy and will cause serious injury or death.

30" apple cinema display suddenly went blank.


It's probably the backlight. If you look very closely, perhaps using a flashlight, you might be able to see that it is still working but just not being lit up from the back. In that case it may be worth fixing, but if not, then it's probably past its useful life.
One other thing you might try is a different power supply.

Blinking light on 20 inch apple display


Blinking light on Apple cinema display usually indicates insufficient power from the power supply. Test it with another power supply from ANY cinema display (23" and 27" power supplies are ok to test with).

Apple cinema display has interference


Check your DVI cable for breaks. If that's not the problem, then you'll need a new IP board. Not sure of the part number for this monitor, it's printed on the circuit board. It starts with 820-XXXX or 620-XXXX in some cases.

Apple 20" display black screen


I've read that aftermarket DVI cable adapters don't work well with this set-up. You might try the Apple DVI to ADC adapter. It's expensive but I see them on eBay or craigslist from time to time at less than half the normal $99 cost.

Apple 23" Cinema HD Display went off


Hey - I just got done with 30 minutes of trying my cinema HD on my macbook pro and plugging and unplugging. When I plugged it into an extension cord in another socket the monitor started right up. I've had this configuration in my office for years with no problem...until today. Did mac send us a system upgrade that caused a problem with the monitor's power source???? Good luck!!!!
