Can't watch the channel, pixcels breaking up, no sound and loses signal

If you are using an antenna for input, then you are probably partially losing sync with the signal. You may want to adjust the antenna or try a signal booster. If you have input from a cable box, check the HDMI cable, possibly replacing it with a new one. If you're using a cable box with RCA cables, (Composite or component inputs) then the problem is most likely with the cable box loosing sync with the channel feed.

If you have a good picture on some channels and the picture breaks up on others , it could be the input signal. What is the source of the input signal; i.e. cable, satellite, antenna???? Do you have a cable box? The problem may be with the box or with the provider's signal.

DUALWATCH/

Description
Dualwatch monitors Channel on another channel;
Tri-watch monitors Channel 16 call channel while receiving another is convenient for monitoring operating on another channel.

•
If a signal is received on Channel 16, Dualwatch/Tri-watch
pauses on Channel 16 until the signal disappears.
•
If a signal is received on the call channel during
Tri-watch,
Tri-watch becomes Dualwatch until the signal disappears.
•
To transmit on the selected channel during Dualwatch/Triwatch,
push and hold

Actually sounds like the feed for your HDD is going south on you. I would get another recorder to verify this scenario. Or, you could supply a local signal to the HDD to verify the problem. Use a VCR, DVD player, or the like to check it this way. The outputs from most local sources will be copy-protected, but you'll have Some signal.

If you are watching adverts that implies a broadcast TV sound signal. What happens is that the broadcaster will switch off sound especially Dolby signals during add breaks. Therefore it could be your TV that stops sending the sound to the Marantz. So check the sound settings of you TV. It might have an auto feature that detects the signals, that could be switched to manual or just a wrong sound signal that causes the problem.

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.

could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

All digital channels need good signals from the aerial. Have you got a good one? Even with a good aerial the cable from it can cause problems. For instance a lot of people have old type coax cable (often brown in colour) and if you have it will lose a lot of signal. For best results replace it with FT100 cable, the same type used for satellite dishes. Lastly bad plugs can cause problems.

if you are using an hd cable box it might be just that. what happens is if the cable company is doing work around your area or some one on your block adds another cable line to there house you end up losing signal for your box. now if you pull the power plugg and let it reboot that could either fix the problem temporarly or not at all. you might need an amplifier hooked up to your cable lines or a new cable box all together. contact your cable provider and ask for some one to test your signal quality. i am also assuming that your not getting the same problem when your watching a dvd. i hope this helps you

Are you watching 10HD off the air from an antenna? You are losing video and audio intermittently, which may just be indicative of a weak signal. Does your TV have a signal meter?
