Glitchy Screen and Blue Screen when turned off. HELP

I received a Sony Handycam from my uncle a few days ago with a charger and it's battery. The camera wasn't turning on with the battery inside but when I removed the battery and plugged the charger in it would work fine. I checked the battery and bought a similar one from ebay. I plugged the new battery in and it worked fine (for just five minutes) The screen got glitchy it says HandyCam while glitching and when I turn the camera off the screen is blue. Please I need to fix this as there are a lot of footages I want from the camera and also want to use this camera.
