I have the same problem as the person you replied to who wrote: **** Dear sir: My Sony MVC-CD400 camera works beautifully when connected to its 120VAC charger, but will not accept a charge, with either of my "INFOLITHIUM NP-FM M Series" batteries. When configured in the charging mode, the orange charging light blinks continuously. With either battery in place the camera will not operate. Would you kindly advise me on repair/replacement options. I purchased this camera more than two years ago. Thanks in advance. FBQ. **** Can you tell me what needs to be done to repair the camera?
