I'm sorry to hear this. It sounds like you may need a new remote control. Please Send me and e-mail at email@example.com along with your model & serial number of the television.
Just purchased my new tv today and when i unpacked it i noticed the remote had a pretty loud rattling noise when it was moved and shook around. i took the battery case off and that was not it. It seems like the rattling noise is coming from within the remote itself. I wasn't sure if any one else has had this issue and if so is it normal and if not what they might of done to fix it.
