I have a dead Kenwood PS909 (was a great head unit) and it has a CD in it still.
This is a "flip face" unit and it died after flipping back to blacked out mode.
I was going to ebay this unit for any audio guys who needed PS909 parts since the mechanism worked flawless for about a week after dying. However, though it would flip around, no input keys were operable so I could not eject my CD, then it decided to die completely.
I'll check the fuse before giving up and taking it apart (if possible) but thought I'd ask first.
