I can't see NBC with the digital conveter box


Is it only NBC? Or are the other over air channels (ABC, CBS, Fox) also not seen?

Are you going through a splitter with the incoming signal? if so, make sure the splitter frequency range is at least 5 to 1000 Mhz.

You should see the 'temporary lost signal' wording on the channel. Check all cable connections to make sure the cable to connector plug are tight and not loose.

Digital channel 25 has no sound.


First make sure SAP or nothing similar is turned on.

After you triple check that just Contact ILO if it continues for more than 1month. This is a software error.

What state are you in?
What channel is this?NBC, ABC
Have you check this at different times of day?

Cannot get local channels back after dropping cable.


Are you positive that your city has not done the Digital Conversion? Some Cities are doing it early before the February deadline. Also make sure you are tuning in to the correct channels. Meaning that if on your Cable Provider ABC was on Channel 3 that does not mean that ABC with still be on Channel 3 after you have your Cable turned off. Most of the Time the Local Stations Tag will let you know what channel its on. It will be something like "KWAS ABC 27" So on your TV you would Tune it to channel 27 to get ABC and the same fore NBC , FOX, CBS , etc...
I hope this helps Take Care =)

Hi ks0412,

If you are receiving a High-Definition (HDTV) signal through an over-the-air broadcast, you may see this kind of mosaic-like breakup of the picture and sound if the signal is weak or interrupted. This is the same way that you would receive snow and static with an analog signal in the past. I would suggest readjusting your antenna for better reception on the channels that are giving you trouble.

If you are receiving this broken signal from a subscription-based service such as cable or satellite, I would recommend contacting your service provider for assistance. It could be a problem with the signal, your equipment, or the equipment setup.

Thank you,
Jason,
Go Ahead. Use Us.

Don't get ABC or NBC local channels anymore


ATSC tuners ("D/A converters") pick up signals off the air just like old school television. It sounds like you are just not getting a signal of sufficient strength. A weak analog signal looks like a "snowy" picture, which most of us are used to. But, the new digital channels quickly go from a perfect picture to none at all. It's basically all-or-nothing.

Try attaching an antenna to your converter. I know you can buy a new antenna from your local big box electronics store which is labeled "Terrestrial HDTV" or something, but that really doesn't mean anything. You can use any old TV antenna. Even a quality FM antenna (with an F-Pin coax connection) may work just fine.

When setting up the antenna, keep in mind that different channels are transmitted from different towers, in different locations with different strengths. Move the antenna placement and position around (just like grandpa had to do). You may have to make a compromise to get the best signal for your favorite channels.
