About sony camera repair issues

This is a common problem. It is most likely that one of the reeds inside is broken, or the transmission part is broken or something is stuck. I don’t know the specific model of your machine. If one of the reeds inside is broken, it only takes a few days to go to a professional maintenance department to repair it, and it won't cost a lot of money. If it is a professional DV, it is best to go to a professional repair department. The accessories there are usually original. If it is an ordinary DV, the price can be lower at a general repair center.
