Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Do you know the model number, there are several of the panasonic lumix cameras. A 4 year old model would be discontinued at this point, but there are newer/better ones that are in the same price range. For example: http://amzn.to/2eXzkvk
If you can give me the model you had I can help you find the best match.
