Question about Televison & Video

All ABC Channels pixelate in evening only.

From the 2 May 2010 at approximately 5.45Pm the three ABC channels become pixelated with distorted sound and continue until late evening.
Daytime reception is perfect with a 3 year old VHF/UHF antenna installed. It is as if someone has thrown a switch on something causing interfernce.

You are possibly very close to the truth when you say someone has thrown a switch.

Take a look around outside, what starts to operate between those hours of the evening close by? Any amateuradio antennas close by? Workshops or night welding shops/neighbors etc? See if any of your neighbors also have similar problems, although you may be in better line of sight, so get the worst of it.

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.

My Samsung is pixelating, but only on some channels

If only on some channels it is not the set.

Cable and Satellite providers compress information for various reasons--sometimes this causes pixels to slow or stop and even drag and smear---perfectly normal even if not nice.

If it was the set it would be on all channels and all the time.

If in doubt call the provider and have them come out and change the box being used or at least offer an explanation.

Pixellation on most channels

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.

Pixelation of TV channels via Settop box

Pixelation is caused by poor signal strength. Check the signal strength in the setup section. Unfortunately some boxes and TVs don't handle poor signal as well as others. It might be worthwhile trying a signal amplifier

Picture sixe reduced and picture breaks up with converter box

You can change the way the channels can be displayed/viewed by a video setting, consult manual. When pic breaks into pixels and sound goes it's usually a reception problem so you'll have to adjust the antenna facing a direction that makes that channel come in clearly. It helps to experiment with positions and antennas.
