I have Directv & I can't get a clear picture on this tv. Tuner mode is set to air because when it's set to cable it will not search for channels. Should I be using air or cable mode? DVD's look awesome even with inferior component connection.

Re: Tuner Mode - Air or Cable?
Direct tv, unless using there HD service will give a pretty crappy picture for high res displays. So if you spent the money on the set, spend the extra $9 a month for there HD service.. Is well worth it.

You should be able to get OTA (over the air broadcast) just make sure you have an antenna plugged in and that the tuner is set to AIR.

as an external antenna or cable TV connection, you must set the

Scanning for Channels
Before the TV can detect and display channels and their
associated information, you must scan for channels. A channel
scan may also be necessary when the TV has been moved to an
area where different free-to-air broadcast television channels are

If you have a cable box and can set your TV to channel 3 then you should be able to watch cable. If you want to watch over the air broadcasts then you need a digital converter box which you can buy at Best Buy for around 40 dollars. You use the converter box as the tuner and set your TV on channel 3. http://www.bestbuy.com/site/Coby+-+ATSC+Standard-Definition+Converter+Box/9663904.p?id=1218140711965&skuId=9663904&st=digital%20converter%20box&cp=2&lp=5
This can happen when there is radio interference near the coaxial cables. Sometimes the interference is behind walls. The solution is to try a different combination of modulation and channel than what the DISH receiver is current set.
The DISH menu screen for this setting is Menu-6-1-5. With dual-tuner receivers, typically "TV 1 Out" is the TV that is connected in the same room as the receiver is located. "TV 2 Out" is the tuner that is fed to the remote TV via backfed coaxial signal.
All that needs to be done is to change the channel and mode going to the effected TV to something different. If your channel/mode is currently set to Air/60, try changing it to Cable/73. When you change the mode/channel in the DISH receiver, you need to set the remote TV to the same mode and channel.
Keep in mind that with some TV companies like VIZIO, they call their "Air" mode "Antenna". With VIZIO's the TV must be set on TV input and then go into the Menu to the Settings, Tuner Settings. Change mode type to match what you are trying on the DISH receiver, exit the VIZIO menu and manually enter the channel number.
Eventually with trial and error, you will find a mode/channel combination that isn't effected by your particular environmental interference.
TV's of this era have two modes that the tuner can work in. One is the AIR mode and the other is CABLE. In the air mode the tuner picks up only "off air" frequencies,... and up to channel 13 they happen to be the same as cable channels 2 thru 13. If you are using cable you will need to go into your on screen menu and find where to change the tuner from "air" to "cable" to get channels above 13. Older sets had a switch on the front and sometimes the back to select the tuner mode.
If the cable is installed correctly, now you need to go to your menu, settings, find tuner mode, MAKE SURE THE TV IS SET FOR CATV not air! Then, go to autoprogram and tv will search for all available channels.
Go into the TV's setup screen and make sure its tuning mode is set for "cable" (may say "CATV"). I'm not familiar with this set so I don't know exactly what the screen will say, but there should be some reference to channel setup, TV setup, tuning band, etc. It's probably set on "AIR" now.
Normally, when set for off-air reception, the set works properly for channels 2 through 13, and 14 up don't tune properly. Since you're getting channels up to 19, there may in fact be some kind of tuner problem. If the TV is already set for cable tuning, you may have found why the former owner was freecycling it. But check that tuning mode.
In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.
Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.
The Scientific Atlanta box was a cable box and recieved CATV signals. The Direct TV box is satellite only. You might check if it has a built in ATSC tuner for off air digital signals. Direct TV in most locations offers the major networks in HD format.
