Hi , i have trying playback a tape in my vcr. I dont know why , but the stereo is on a point! This doesnt happen with my other vcrs! It is a Jvc hr-s7700 and when the video playbacks the tape is going to track it automatically but the sound that i got is mono. I only can get sound stereo with manual trancking and always there is a noise , like a bee ! This is the first time that happens to me , with the other tapes seems to go OK. Any advice?
