Hi,
I have a Sony Compact CD Player (Walkman), which was bought in the US. Oflate im having a strange problem with it, inspite of inserting a Brand new battery, within a minute of playing the player stops saying low battery..tried different types of batteries and still have the same problem.
Can some one suggest a good electronics repair shop where i can have this checked out. The problem looks simple, so i dont want to take it all the way to SONY, as it does not have warranty anymore. And i guess for the price of getting it serviced at SONY, i can buy a new one?
Pls suggest.
Thanks.
