Vcr playback sound interruptions

Question

I replaced the TV a few months ago. Before that I had no playback problems. The TV is a Dynex, DXR24TV, the VCR is a Panasonic PV-9400.During the normal play mode sound intermittently drops and returns for no apparent reason. When I place the VCR in Action or Program mode where there is no video, the sound is uninterrupted.There is the occassional picture rolling in addition to the lost sound. All of these problems make VCR viewing impossible.I have no idea how to solve the problems. Can you help?Keith [e-mail]
