Have TV Questions? Ask a TV Technician
Hello, On that one analog channel that showed up- please leave the TV there and then use the Comcast provided remote to attempt to change channels (not the TV remote). Then let me know what happens.
Okay. When using a DTA box you scan on the TV- which will pick up one channel, then you use the Comcast remote to change channels. This is how it's designed to work. So can you please tell me where you're having problems?
Hello , my name is Jack
Perhaps I could help by explaining this ;
Those small boxes are made for older analog sets at present and do not let anyone view in HD which is what the HDMI cable/output is usually for and yours only has a RF output on channel 3 .
The DTA you have now is made for receiving the expanded basic/digital starter channels , no HD/digital can be passed through an analog connection like you have now
You will a need full HD cable box connected HDMI if you want full digital signal.
Talk to Comcast and they will confirm this.
