Need a manual or tech help. Somehow I managed to get a series of yellow numbers displayed on the bottom of my display. Currently it's "9 B 10 3F". I know the "9" is the channel, but the rest of it ... no idea. I just want it to go away and return my tv to "normal operation. I think I've tried most selections available on my generic (replacement) remote. No joy so far. Any ideas? jere47@netzero.net
