Because your problem appears after 1 hour... suggests me that your TV's tuner unit or cable box is at fault.

After the unit generates heat, the components (capacitors) in the tuner is affected and throws off the frequency of each channel.

  • if it is the TV monitor's tuner rather than the cable box, then you would have to have it serviced by a repair facility.
  • if it is the cable box, just call your cable company to replace the box at no charge to you.
Good luck!

Does not show anyHD channels.


Try reinstalling the channels. Its good to reinstall the channels at least once every month. Just go into the set up section.in your menu. Some times our channels disappear when our hydro goes out.

Fuzzy picture


Sounds like an AGC [Automatic Gain Control] problem with its video IF stage circuit. Contact any service technician, or service center. This is not a user repairable fault.

Dear you! When i scan the channels i get them all over from ch 1 to 100 but i only have 40 channels.. my question is how to put them from 1 to 40 in a row? greetings


Hello, probably you did an automatic channel scan, to define a particular station within a particular channel. You need to scan channels manually. You click on the menu and go to the part of the scan channels. There are usually guidance by stages. Let me know if success, good luck!

I have a Magavox television and the channels will not show . All channels are fuzzy. It will get only numbers starting with channel 49. I need to do a channel search to get all the channels to show.


have a magavox tv combo, with dvd and vcr. It will not stay on unless you put a tape in and spend 30 minutes to an hour turning it on and it goes off automatic. Less than two years old.

Guide listings are incomplete


1. Manually scan all channels on your TV with your TV remote and write down the channels and network shown:
(sample: 119.2 C-SPAN2 digital channel).
2. Go to Edit Channels and find the icon for C-SPAN2 (about icon 261 in my zip code). Manually change the channel from Off to On, Insert the frequency, and optionally insert the number you want the channel to show in your channel listing ( or move it manually later).

I have about 10 to add each time I reset my recorder.
