On playback its intermitant, by pressing stop and then play it will play for a few seconds then stops again' then you have to go through the prosess again.Can anyone help please.
It could just be a case of cleaning the lens with a lense cleaning disc, although judging by your description, I doubt it.
Your best bet is to send it to Jim Hoggarth (see link below) and he'll fix it for 10 quid.
Very reasonable I'm sure you'll agree. I don't work for him and am not linked to him in any way but it is such a good and cheap service that I felt I should let you know about it. It just makes sense rather than risking doing more damage by trying to fix it yourself.
I hope this helps.
I can help ...
