I have a sony 27 Trinitron with tuner issues. the picture is fuzzy/snowy on most channels. I have inspected the cable coax and it is not an issue. the problem started shortly after an electrical storm. I...

The RF amplifier in the tuner has been damaged. You will need to replace the tuner. A suitable replacement tuner from a wrecked Sony tv would be you cheapest option.

We want to hook our small Magnavox tv to a rabbit ear antennae to get only local stations. How to do this?

Unless this a new TV with ATSC (digital) tuning built in, you will need a digital adapter for off-the-air reception. Older TV sets have analog tuners, and analog broadcasting ended in June 2009. Wal-Mart and Radio Shack carry the adapters, as do other retailers. Your antenna connects to the adapter, and the adapter sends the converted signal to the TV on channel 3 or 4.

With digital broadcasting, a strong signal is necessary. Unlike the analog days, when a weak signal just meant a fuzzy picture, a weak digital signal will cause pixellation (blockiness) or freezing of the picture, or may not even be detected by the tuner. Depending on how far you are from the station's transmitter, you may find that rabbit-ears may not work too well. You may need an amplified antenna or even one outside to get best performance.

When using cable input video is good but sound has fuzzy static

Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

One channel fuzzy

Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.

Tv only has select channels

If you have a good cable signal connected to the TV and it receives channel 50 nice and clear but all lower channels have nothing but snow, then the tuner is defective and needs to be replaced. This is quite an easy thing to correct. Sometimes resoldering all connections inside the tuner will bring it back to life, but in either case the set should be serviced by a qualified tech.

The set you have has a bad tuner assembly. At this point most likely you would be better off getting a new TV set. Good Luck
