The pixellation on cable channels usually indicating poor/weak cable signal. You may want to have the cable signal strength check out by the cable company, check your cable connection at the entrance of the house to make sure they are clean and tight, try connect and disconnecting them. You are not the cable company cable box are you? My had to be replaced twice by Comcast, they were running very hot.

What causes pixelation only on digital 9 TV and there subsidiaries


Pixellation is a weak and noisy signal coming in. Digital HD needs a good signal at the antenna socket on the back of the TV. You need to have good quality quad shield coax cable down from the antenna, and preferably crimped F-connectors at each plug and socket. You may even need a new digital antenna if you are making do with an older analogue one.

Your other stations will also improve.

How comes that my LG TV 32" model 32LC20 has problems sound and pickture with ABC channels all other Channels are OK ?


If the audio is distorted to certain channels only, it is due to improper AGC adjustment. Weak signals won't processed well. You have to enter the service mode to the set, and have to adjust this value. This is somewhat skilled work, that a user can't do. It will be best to contact any service technician, in this case. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

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.

I got a hd box and the channels keep cuttin out


Hello, I actually install HD boxes for Verizon Fios. If your video signal is too low, you will notice "Pixellation" (Those weird square boxes that come and go) and in some cases, you will not even be able to receive some channels at all. HD channels use much more bandwidth than standard definition channels. The good news....there's a fix. If you use standard cable (Not Fios) you can buy a signal booster. These can be purchased at best buy, Radio Shack, etc. It is a powered device that plugs into an outlet (110v) You take your cable company's input or "Feed" run it into the booster, connect the power, and the run a coax cable out of the booster and into your splitter. Assuming all of your cabling is up to par, this will fix your problem. If you have Verizon Fios, you must call and have us come out as our tv service uses "Moca" and cannot be boosted with a store bought unit. I hope this helps.

My LG 42" keeps losing signal and breaking up on


Lost signal could be several things. Check that you have good connections and that your co-ax cable was made in this century.
If you are using over the air look for obstructions like trees or buildings blocking the antenna signal.
If you have cable that one is easy, have the cable guy come out and test your signal strength. 98%b of them will do this for free.

Vizio pixelation in hd nt all channels


Usually a TV that pixelates only on some channels is a problem with the signal levels coming into the TV or the cable box. If you are using a cable box then definatley the signal is the issue..

No antenna signal nor found channels for my area.


You'll need a better antenna to solve your problem. With the new digital broadcasting, signal strength is everything. With analog, a weak signal would give you a watchable but fuzzy picture. A weak signal with digital gives you nothing, or possibly a picture that freezes up or breaks into blocks (pixellation). The only cure is a better antenna, either an amplified indoor antenna or something outside.

Sad to say, there's no guarantee that will work. If you live too far from the station, or have hills, buildings or other obstructions that block the signal, you just may not be able to pick up some channels. In some areas people have found they get no reception at all.

At www.antennaweb.org there's a tool that will tell you what stations are around your area and how far. It's designed to help you figure out what kind of antenna you might need.

Pixellation and sudio loss


The digital signal is sent over UHF(13-69) channels (unless you are in Chicago which uses VHF( 1-12). You will have signal loss during rain. You can get a stronger antenna and put on a pole outside your home which will help keep the signal stronger.
