Why won't my TV get all the channels any more?

Why does my TV only get 15 channels when it should get about 70? How do I fix this? ?

• The problem is not the cable chord or the connection because other TVs work when they are plugged in. Only the low channels come in and the rest are just solid blue. What is wrong and how can I fix it so I get all of the channels that I should be getting? Getting/using another TV is not an option.

• Answer:

  This should be easy. First assuming your TV is indeed cable-ready (any sold in the past 20 years should be), look for a switch or setting in the menu for "antenna" versus "cable". Set it to "cable". The reasoning here is that channels 2-13 are the same for antenna and cable, but antenna channels 14-69 are totally different frequencies than cable 14-100+. Actually there are a few frequencies that do overlap in the UHF band so that's why you probably pick up a few beyond ch 13.
