Also have a Samsung HLN437WX

I have a samsung HLN437WX. I have had it a long time now. It came from my mom and dad when they got a new one. It was used very little. It was doing just fine then one day I turned it on and it would not change channel, volume the menu would not come up. and the remote dont work, its like it just locked up. There was still a picture and sound. But whatever you had it on is what you watched. And now when I turn it on, its still the same but now no Picture or Sound. Now, If I keep turning it on and off it will sometimes have sound but no picture. Can you please help me? Thank you.
