I recently got a basic cable plan but am only getting a couple of channels.. How can I change this?


The best thing to do is contact the cable provider and ask them to provide a list of the channels you are suppose to get. With all the channel mapping and digital TV display devices these days, you might need to have your display device scan for channels if the signal is not tuned through the cable box itself. The channels may be there but the tuner in the TV device has not scanned the channels to register them into it's memory. Also make sure to set the TV for a Cable mode of tuner.

Hi, I live in a flat in London with a shared rooftop aerial (no idea of spec). I have a Sony KDL-46X2000. The built-in freeview tuner doesn't seem to recieve any HD channels. Is the built-in tuner the...


Make sure you have a good connection from antenna to TV. Check antenna and cable and cable connection to TV. Select DIGITAL button on TV remote when wanting HD channels. Remember HD channels are always digital. Also, any given TV station may not be broadcasting in HD at a given time. They can broadcast in digital but in standard definition sometimes. Your TV has a built-in DVB-T tuner. Try executing a channel scan to pick up all available channels. On-screen menus go to Digital Setup, then Digital Tuning, you can auto-tune or manual tune channels. The TV should take a few min. to scan thru available channels and store the channels its finds. Check with anyone in your area to see if they get HD channels (it is possible to be outside of the range of some TV stations) Your TV is a 2006 model and should still be compatible with local digital TV broadcasts but keep in mind digital signals could change in the near future (DVB-T2) and you may need a tuner/converter box to make the TV compatible.

My tv will scan and receive channels on a antenna but will not pick up channels on a cable scan with a good cable and a proven good cable signal


if you are not using a cable box and trying to connect cable directly to tv you will get very few channels since they are all digital now and most are scrambled

you will need to hook that cable to the input labled 'QAM' and program tv for digital channels

if you are coming out of a 'cable box' you just need to hook up video cables to an input on tv and change tv to that input - no scanning necessary

hope this helps - if not write back with more details and i will try to help more

good luck!

1. Make sure you have connected the cable to the correct input on the set.

2. Access the User Menu and do a "Scan for DIGITAL" channels.

That should do it...

Can't get HD cable channels on Samsung TV


Have you check with the cable company to make sure they are broadcasting to you in HD ?
It takes more bandwith so some cable companies will charge extra for it so you will have to check.

How do I turn on the digital tuner? Samsung


Hi my name is Roety,
I can help you with your issue ,
The digital tuner is always on, you just need to run the autoprogram in the setup menu with a digital signal connected.
An antenna is ant or air signal
using Cable click cable when scanning in channels.
If using a cable box there is no need to scan channels.
if using an indoor antenna it may not pickup any (roof antenna is better)

I will reply asap
