Hi. My name is*****'m a technician with almost 30 years in the business and I'll be glad to help you with your question today.
The problem with these chargers is usually in the end that plugs into the device. The wires at the base of the insulated tip will bend and break. They can make contact sometimes and provide power but will usually require replacing the charger. Here is a link to the Sony website with the authorized parts distributors. You should be able to find a replacement charger there.

Just a note to see if I can be of any further assistance?
