There's absolutely no chance that someone will remotely "fix" my camcorder, although you never know! To retrieve a tape, I dismantled an old Blaupunkt Camcorder. I successfully transferred the tape to my TRV820e and it played without any issues.
However, things took a turn when I fast-forwarded a few times and inexplicably removed the memory stick. After that, the 820e refused to play back any tape, displaying only a blue screen. Furthermore, I noticed that the tape counter stopped working after I removed the memory stick. It could be a mere coincidence, but I have a nagging feeling that I inadvertently triggered something while removing the stick. It doesn't make any sense.

I even attempted troubleshooting by removing the battery for ten minutes, trying different tapes, and recording on a new tape, but nothing worked. Best of luck to anyone who tries to fix it!
