Cassette removal from dead Canon MV650 Camcorder

Question

My Canon MV650i MiniDV camcorder died after 5 years of sparing use. The authorized Canon service center cannot get the spare part (DC-DC board).But there is a priceless tape stuck in the machine! I have (carefully) partly disassembled the camcorder. Is there a way to manually eject the tape?Hannes
