Bad IFU or pc engine CD docking station

[Keith Courage]

Has anyone here ever done any repair work on a pc engine IFU before? I am talking about the CD briefcase docking station. I have come across a few bad ones here and there and was just wondering if anyone has ever tried to repair one or just not bothered since they don't cost so much. The problem I speak of is where CD games will load to the title screen but then when you go to start the actually game it freezes up usually with scrambled video and a loud audio tone.

I believe thesteve has done some repair to them.  Might wanna send him a message.
