Hello and thank you for your question. I look forward to assisting you today. Do you have an AC adapter you can power the camera with?
Okay. Then you have most like have a couple of things going on. Either the AC adapter has failed which also charges the battery, or there is an open fuse somewhere on the circuit board of the camera? The first may be easy to check if you have a volt meter and can check to see what the output of the power supply is.
Do you have a way to check the AC adapter?
Still with me?
Let me know if you need further assistance and I will return as soon as possible.
