Hi everyone out there, I have a little used Sony CD-TR808E Hi8 camcorder that I bought in 1993 (and several lenses for it). I recorded some 25 cassettes in the nineties that I was going to digitize on my lap top. However, this plan has been sabotaged as the camcorder won't load cassettes anymore. I took it out of storage yesterday, connected it, had it eject the cassette that was in it, put the cassette back and then the cassette lift refused to go down. Every six seconds a motor inside starts humming for some nine seconds, stops six seconds, hums nine sconds, etc. tc. But the lift won't go down. Can anyone help/advise me? Thanks in advance!
