Herein is the continuation of a saga that started in the Finds thread. I found a CECHG01 fat PS3 at Goodwill last week. Took it home, hooked it up, and it works fine aside from not pulling in any discs. So I tear into it, realign the mechanism (after getting it to make the machine-gun noise on a reset), and while I was in there I noticed that the optical sensor is completely missing. Got one of those from ebay, installed it today. Now it gladly accepts and ejects a disc. Only problem is it doesn't seem to do anyting other than light the blue LED. Is that a laser or some other problem? And whatever it is, trusted part seller recommendations and other info are greatly appreciated. Thanks!
