Hi, I've been given a reasonably new Changhong TV with no manuals at all. I watched it for a few weeks without any problems. One day the remote fell from a chair and I grabbed it, pressing some buttons in the process. Suddenly, an onscreen display of the TV's name and functions are displayed. It's just a band that scrolls down the screen every 30 seconds. If I press any button, it disappears, only to appear again after 30 seconds. How do I get rid of this from the screen? Regards, Peter
