Hi Joanne,I suspect that video heads are defect or in need of cleaning.Running a cleaner tape may correct this problem and restore normal operation.If problem persists,video heads would be in need of replacement.However,this part,if needed is no longer available and most likely would not be economical if if it were.The most cost effective route(if cleaning does not correct),will be to check a site such as ebay or amazon for a used 8mm camcorder in which playback is functioning proper.All 8mm tapes and camcorders will be compatible and will allow you to copy your memories.
If you have any other questions please ask....Best to you,Joe
Is a cleaner tape something that might be readily available, such as Radio Shack
or camera store?
Hi Joanne,most stores are no longer carrying a cleaner for 8mm models.I have found some available at Amazon,here is a link....
Have a great evening....Best,Joe
