Q: Black screen but still powers external hard drive

I have two Cinema Displays, not thunderbolt, hooked to a new iMac 27". I took the first one to an Apple Authorised Repair Center and was told that either the logic board or power adapter were shot. The monitor is too old for them to get parts from Apple, so I went and bought a used one from ebay a year ago. Now this monitor just went black while I was working on it. It still powers an external hard drive that appears on my imac, and the light on the front still pulseates.

Both these monitors are the chrome edged 23" HD displays. One is an 07' and the other 11' neither are thunderbolt and neither have a camera. Any ideas. My Apple authorised tech shop said i can have the later one replaced by apple for $670. I don't want to spend that much when I only paid $350 off ebay. If it was just the power adapter I would buy just that, but who knows?

23' c, OS X Mountain Lion (10.8.5)
