these guys (and gopal electronics) are known to repair anything for a very reasonable charge. you also get all the accessories and parts that have failed your precious appliances!
Gopal elect is a small outlet in the bylanes of chembur where one can expect to get anything from the tv remote to a huge music system repaired. They also have a variety of small items like remote controls, chargers, etc which generally tends to get misplaced or damaged.
