How to clear channels and start over - Uniden BC246T Handheld Scanner

See if the tuner on the TV has a provision to add both analog AND digital channels as a choice. If so, then select that and then do a new channel search. Ask if the cable company uses standard or irc channel spacing and set your tuner on the TV to match.

if your using a dish then alignment should be fine if your getting some clear channels, maybe try a new install of all frequencies

I think you are confusing the channel on the tv and the channel of the cable company that is not something that you can pick up with the scan tv, scan tv is good for picking up local channel meaning air channel that we get with a antenna only not the cable chanel

Turn off the scanner.
While holding down 2, 9, and Hold, turn on the
scanner. It takes about 3 seconds to initialize
and "CLEAr" appears.
The above is from the "Resetting the Scanner" section on page 53 of the manual.

Is your t.v old. If yes this can sometimes happen. All you have to do is take those channel, tune them BACKWARDS a little and then set the channel as required and then store. Do this for every channel separately.

Take you unit to a service center and ask them to fix it. They won't be able too, but ask anyawys. When they tell you they can't fix ask them for the work order and then call 1877-297-8391 and they will help you

Programming a frequency into a channel clears the previous channel entry, so there's really no need to "clear" the scanner for reprogramming. To eliminate an unwanted frequency, you can either press the LOCKOUT key to prevent the scanner from stopping on a specific channel, or you can "zero" a channel:

1. Press SCAN/MAN to stop
scanning.
2. Use the number keys to enter
the channel number (1-200)
you want to clear.
3. Press PGM. F=C appears.
4. Press 0 then ENT. The
frequency number changes to
000.0000 to indicate the
channel is cleared.

There is no global clear/erase function on the BC350C, but programming a new frequency on a channel automatically deletes/erases the old frequency. To delete an inactive or troublesome frequency, program "000.0" in that channel. Doing so will deleted the previously programmed frequency and set the LOCKOUT to ON for that channel. For more information on deleting frequencies, see page 27 of your operating manual.

There is no need to clear the scanner before reprogramming. When you enter a new frequency it will automatically overwrite the old frequency. To clear unwanted frequencies you can program "0.0" into any channel to clear it, or simply use the LOCKOUT feature to prevent the scanner from stopping on a channel.

Well, there is nothing wrong with the TV itself. The signal is too weak to get enough digital information to complete picture and sound.
You may need a better antenna for reception.

There are some long range digital antennas and antennas that will receive signals in all directions.
It's the best way I know of to solve the problem.
