Sony Cybershot only works when plugged in

Are you sure it is your charger and not the battery? (Batteries)

You could buy a new Sony charger, but there are lots of universal camera battery chargers, that won't cost as much and you can use it for every battery from every camera. Pick the right one and you have a charger for years to come, whatever your new camera will be and how big or small the batteries are.

You either have:
1) a false positive on your battery, meaning that they aren't really charged even though they say they are (especially common the older a battery gets), or
2) the battery connection is faulty/dirty, while the AC adapter is fine. If the AC adapter uses the battery port, then the battery is your problem.

this problem is by the DD board of the camcorder their is a power ic in the DD board,which provides the supply to the camcorder.

I replaced the battery. The new one keeps a charge and lets the ac adapter charge the battery. I plan on purchasing a new battery and recycling the old one.

Does it power up if connected with AC Power Adapter?
Have you tried extra AC Power Adapter or tested with another Sony Camera?
Let me know to guide you further.

try going into the menu and doing a camera reset this corrects alot of connection issues. hope this helps.

oh no maybe you used different adaptor some adaptor have reverse polarity. check the adaptor before plugging it..if you using variable voltage set to 3v then adjust also the polarity. the polarity should match the polarity of your camera.
