Do you mean frequencies above channel 30? Otherwise perhaps the set cannot store more than 30 channels? More info required to be certain.

Check and replace its main system control memory IC. If this IC is faulty, auto tuning will not work, or, the TV will store any received channels. If the TV do not tune into channels too, the AGC voltage to its tuner, and tuner itself should be checked.

When we turn on the TV the channels wont go past 13 not sure why. the other tvs in our house goes up to channels 65 Lost the manual

If the tv was setup with auto tune it will only store the amount of channels(signals) that it can pickup
so if the signal is worse on that outlet it will find and store less channels

I can't program channels above 13

Check your TV settings and be sure to set the tuning mode to cable (sometimes it says CATV). You will find it's set to "air" now. When set for off-the-air tuning, cable channels 2 through 13 work fine, but above that you get nothing. After you set your tuning mode to cable, rescan channels and ou should have everything.

Tv channels wont store on lcd tv,you have to programme them back in after its been switched off

apparently the  the TV resets the channels bewtween 2:00 AM and 5:30 AM, so by changing the clock everyday to ensure that it never reaches this time should resolve teh problem, or just try an not set the clock at all if that is possible, my parents are having the same problem and ive heard changing the clock works, still frustrating, currys have been warning people off buying them due to " tuning malfunction" feel free to take it back to the store and get a refund

Tuning in the tv

Most TV's auto search feature will try both the Cable and the Air frequencies, but perhaps yours doesn't. Go to the menu page for tuner setup and make sure it is set on Air (might be called broadcast) and then run the channel search.
Cable channels and Broadcast channels (above channel 12) are not the same frequencies.
Hope Ya Fix It!

Cant get local channels

If you can manually tune to the channels with no problem, then I would go in and add then into memory manually. If not then exchange the set as it might have a bad tuner or an AGC (automatic gain control) issue.
