I have a audiovox portable DVD player from ten months now. It is a 10 inch portable player and the model number for it is PVS33116. I always use this to watch movies on Dvds everyday. For charging I plug the charger in overnight. But yesterday when I finished watching and plugged the charger in it wont charge. Now it says that it has low battery and it wont charge. Please tell me what should I do? Has the charger gone bad or the dvd player battery?
