I haven't used my Canon mv890 for a while and on switching it on the blue screen appeared Ok. After charging the battery the camera refuses to do anything The blue screen is now white and the cassette wont eject. I've changed the small lithium battery and tried another main battery. Both the main batteries seem to charge OK. I've also tried running it off the mains adapter. It's a though it wants a total reset but I can't find a button or set of actions to achieve this.

Anyone any clues as to a way forward or can you recommend a good landfill site?
