I am getting a weak signal on the left channel of my T.80 on both digital and analog outputs.

You will need a digital to analog converter which you can get at Radio Shack, Best Buy and most big box retail outlets or online. Your Coby is most likely analog and will require the digital signal to be converted to an analog signal from the digital converter box to the TV. UNLESS the digital converter box has analog (round connectors on the back) then you just need an analog RCA cable (which you can also get almost anywhere even your local CVS/Walgreens) to make the connection.

If you're trying to get off-the-air reception here in the US, remember we switched to digital broadcasting and the old analog stations are off the air. This means that if you have an older analog-only tuner, you'll need a digital converter box to pick up the new broadcasts. Before the switch, the US government offered coupons to help pay for the boxes, but that's long since gone and you'll have to pay the full price. Radio Shack, Wal-Mart and Best Buy all carry the converters, and you can find them online as well.

Be aware that even with a converter, you may still not get a signal. With the new digital broadcasting, signal strength is critical. With older analog broadcasts, a weak signal could still give you a watchable picture. But with digital, weak signals may not even be detected. People living in some areas have found that they get no off-air channels or far fewer channels than they did before the switch.

Much of the trouble is because of the line-of-sight nature of the new digital system. With the switch to digital, broadcasts moved to new higher frequencies that don't spread out or follow the Earth's curve like the lower analog channels. Many people have found they needed to put up rooftop antennas pointed toward the station so they could pick up a signal. This is especially true if you live in a valley area or where there are many tall buildings between you and the broadcaster.

Good luck with your reception, and thanks for using Fixya!

switch input cables and try this will confirm if the amp has a problem or the input signal

You may have had the receiver set to "Stereo" mode, or Analog instead of "Digital" or "Auto" (automatically switches to digital when it detects a signal) modes. Also, setting it to "Direct" (2-channel from an analog source) could result in loss of center channel. Or your Surround Parameter dial (on the higher-end Denons, at least) could be set to a 2-channel mode.
Finally, if your digital inputs are incorrectly assigned (e.g., COAX1 instead of OPT1, or OPT2 instead of OPT1) for that source, the receiver will use the Analog signal which is stereo-only. You could get a center channel via Dolby Pro Logic II but it would be a "matrixed" signal, not the "real" center channel you could get via digital input using Dolby Digital or DTS.
(If all else fails, re-check your center channel speaker wire connections. It's very unlikely, but also possible, that either the receiver center channel amp or the speaker has failed.)

Welcome to the world of off-the-air broadcasting!

First, be sure you have the TV set up correctly and that is in fact capable of digital tuning. Just because a set was sold as HDTV doesn't mean it has a digital tuner. Small TV sets weren't required to have digital tuning until shortly before the switch from analog. This set may require a digital adapter. If the set does have digital tuning, be sure you have "air" selected and not "cable" for your tuning mode. Also let the set scan for channels.

With digital broadcasting, signal strength is critical. In the analog days, a weak signal would give you a fuzzy picture, but you could see something; with digital, a weak signal means you see nothing at all. You may live in an area where the signal is too weak without using an amplified indoor antenna or putting one on the roof. Your location, other structures around and weather conditions all affect digital reception as well. Many people were (and still are) upset to find that they just couldn't get any channels at all once digital broadcasts took over.

I hope this has been helpful. Thanks for using Fixya!

try doing a rescan of the channels, might also be new RF signal obstruction in the area, try re pointing your antenna a different angle, this helped me once when a weak channel was freezing often.

S video connector is used only for video, you need to connect the audio separately via the RCA audio connectors or via digital coaxial or optical connector.

You can read more on S video standard here:
http://en.wikipedia.org/wiki/S-Video

Also see the related topics on audio, maybe you should consult the user manuals for your dvd unit and the amplifier that you use to get more info, but normally the sound can be connected via these connectors on the rear panel of dvd units:

- main left and right analog signal out RCA connectors (2 channel stereo signal - amplifier set to analog signal)

- main left and right, sub, center, surround left and right analog signal out connectors (multichannel surround signal - amplifier set to analog signal)

- coaxial digital signal out RCA connector (a single cable that takes the stereo or surround signal to the amplifier in a coded digital form - you need to set the amplifier to the digital signal mode to enable this kind of signal)

- optical digital signal out connector (same as the coaxial digital output, the difference is that the signal is in the form of light pulses instead of electrical pulses - the amplifier should be set to the digital signal mode as well)

Hope this helps somehow - if it doesn't, post me some feedback, perhaps a brief description of the units that you want to interconnect...

if u have placed your DVD next to your tv ... just maintain distance between then and check out

When the Government decided to make all stations go digital, most places we're telling about the change over. But what they forgot to mention to the ones like you that you may have to change your outside antenna. They make antenna just for picking up digital signal. So you may have to change that also. be Sure and check the cable going from the ant. to back of the converter box is in good condition or may have a break somewhere that could cause more trouble. If you see any bad places on the cable you may want to replace it now when you do the antenna.

Best solution would be to use an outdoor antenna with an amplifier(booster)--but in some areas you may get by with an amplified set top antenna. Just all depends on your location..

In perspective, I have an outdoor UHF dish and 10 foot VHF antennas with an amplifier and still i get only fair reception on outlying digital stations that normally come in clear on analog.


Also--this converter box must complete the autoscan with an antenna attached, or else you'll receive NOTHING; not even by manually selecting a known digital channel.

This #@!! box automatically locks out what it considers to be unused or weak channels. It makes the decisions and you're left with 'no signal' messages and nothing to do but try a rescan.....and you cannot add channels to any it has already found.
