Hi everybody! I have an used Samsung VP-W70 analog HI8 camcorder - with somekind of error....- motor and mechanism works fine( I can see picture through viewfinder) but there are only white "snow" then I play back my recordings and if I push record button - its like recording footage and working but I dont see anything after that - only white "snow"- like it is a new empty cassette. The problem occures suddenly - first there was a error message "protection" - then I turned camera off-and-on -after that the message disappeared and I find out that I cannot see my recordings. Maybe camcorders playback-head are dirty - but I thought that - if they are dirty then the picture disappear gradually not suddenly or what
