Tv saying weak or no signal

SOURCE: weak or no signal message

1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
2. I looked at the manual for my Samsung 750 model. 
3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.

If you just have over-the-air signals from local broadcast stations, you need a good VHF/UHF antenna connected to the RF input jack on the TV in order to get reception. If you have access to cable TV or satellite, you need to connect the box or receiver set-top-box to the TV using a HDMI cable. You need to select on the TV using the remote, (press the MENU button) setup for tuning channels. Do a scan after setting to AIR or CABLE so the TV picks up all available channels you can get. Once this is done you can change channels and see TV. If you reply back with specifics, I can help more...
