Question about Sony KV-13M20 13" TV
Only have a hand full of channels from the cable
Either that of your tuner block is acting up. Most Sonys of this production year uses a tuner block that requires 33VDC tuning supply. It has been known for this zener to fail or the capacitor parallel to it. At times, it could just be the tuner block itself.
Should you venture a DIY, it would be to your advantage to have access to a service manual or at the very least a schematic diagram with voltage readings.. It further requires familiarity with electronic components and circuitry, use of a DVM and a soldering iron. Should you be uncomfortable going this route, then perhaps your best bet would be to seek the services of a qualified professional
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

SOURCE: doesn't get all cable channels
With the menu set to cable signals, the autoprogram should catch all of the cable channels. The Cable Channel option allows you to use either channel 3 or 4 as the "cable" channel. This is when you have an external box that you use to tune in cable rather than the TV directly. The easiest way here is to autoprogram the TV while playing a VCR tape. That will insure that channel 3 is included.
Does the autoprogram fail?

When TV channels are moved from one frequency to another frequency that was previously used by a different channel (sorry, but there's no simple way of saying that !) as has happened recently in th UK, some digital TVs and digiboxes struggle to sort the channel list out properly and channels can go missing as you describe.
If your equipment has the option to delete all currently stored channels (normally in the tuning menu options) then do so and then do a full re-tune.
Sometimes, this solves the problem as the equipment is no longer aware of any previous use of a frequency and just loads every channel it finds.
If this doesnt work, or your equipment doesnt have the option, then there is normally the option soemwhere in the menus to retore the item to "factory defaults/configuration". This will clear all previously stored channels and after a full re-tune your missing chanels should be there. However, any other configuration changes you previously made, e.g picture size, output type (RGB/NSCT/etc), etc will be lost and you'll need to set these again.
NB. some regions of the country have lost some channels temporarily now until after the switch over programme completes at the end of 2012. If you visit the Freeview website, this will tell you if your area is affected.
