If at first you don't succeed, hit it! TRV460
Was devastated yesterday when my tapes wouldn't play. They were grainy with lots of horizontal streaks. Tapes from 20 years ago, kid's birth, etc. I checked tapes from 10 years ago and they worked ok.
Went to a video transfer place and it looked fine on their machine, so it was obviously the camera. Head cleaner made no difference.
Then I found this thread, gave it a whack, and now it works! I had to tap mine on the top of the camera.
I have a Sony TRV460.
Thank you, posters.
Thank you Internet!
