Q: Cinema Display 30" Dead - Could it be the Power Adapter?
Monitor: Cinema Display 30"
Computer: Connected to a MacBook Pro Mid 2012 Retina with a 2.6 GHz Intel Core i7, 16 GB RAM,
Graphics: NVIDIA GeForce GT 650M 1024 MB
I've had the Cinema Display since 2007. Used it with a Tower for the first 5 years, replaced the Tower with a MacBook Pro in 2012. Drove the CD with the laptop using a Thunderbolt > DVI adapter for about 3.5 years, worked ok. Finally, the Cinema Display just went black. The LED in the corner still glows when powered. I can still use the power button on the CD to turn the monitor on/off, sleep the system etc. the MBP still sees the CD in the monitors when the adapter is plugged in. The CD can still drive USB devices. But there is no image, no matter what I do.
Finally hauled the old Tower out, and connected the CD to it, just to see if it was something with the MBP. Same results, no image.
I did notice that the Power Adapter brick stays cold. Could it be that this has just gone bad, and I could replace it for relatively little cost? I'm seeing prices of $150/200 on Amazon. Don't want to mess around with this much more, it's a 9 year old monitor. But I really loved it, and would like to see if I can get it fired up again.
Thanks.
MacBook Pro with Retina display, OS X El Capitan (10.11.3), null
