I recently hooked up my dtv box, tuned the antenna and have a great picture. On every channel I have background noise. Sounds like bacon frying, hissing noise. I also set up someone else's tv, very simple. Converter box and antenna and they have the same effect. What can be done about it.

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.

Tries hook up to a roof antenna or a better antenna like a digital antenna.Than rescan ur tv again,for those DTV free air channels again.Ur tv now,should get all those DTV free air channels.

Use an Antenna that Provides Good Reception of All Channels

• Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
  
• For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
  
• Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
  
• The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
  
• Many antennas currently being sold as “HDTV Antennas,” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
  
• To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
  

Check Your Connections

• Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
  
• Ensure that your components are plugged in and have their power turned on.
  
• If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
  

Perform a Channel Scan

• Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu. Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
  
• Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
  

Adjust Your Antenna

• Small adjustments to your antenna can make a big difference in the number of digital channels you can receive. If you have an indoor antenna, try elevating it and moving it closer to an exterior wall of your home. After adjusting your antenna, perform another channel scan to see if your reception is improved.
  
• While adjusting your antenna, it may be helpful to access the “signal strength meter” on your digital-to-analog converter box or digital television to determine whether your adjustments are improving the signals’ strength. The signal strength meter is usually accessed through the menu feature on your remote control. Refer to the owner’s manual of your device for detailed instructions on how to access its signal strength meter. Remember to do another channel scan after you have adjusted your antenna.
  
• Television stations broadcasting in digital use both the VHF band (channels 2-13) and UHF band (channels 14-51). Many indoor antennas use “rabbit ears” for the VHF band and a “loop” or “bow-tie” antenna for the UHF band. Make sure you are using an antenna that covers both the VHF and UHF bands and have connected it properly.
  

If You are Still Having Difficulty:

• Until June 12, 2009, some stations will be operating at reduced power levels. If you are not receiving certain digital TV stations, this does not necessarily mean there is a problem with your antenna or digital-to-analog converter box or digital television. Check with the TV station to find out whether they are planning changes that will improve reception.
  
• When an analog TV signal is weak or receives interference, static, snow, and distortion will often appear on the screen. Digital broadcasting will provide a clear picture; however, if the signal falls below a certain minimum strength, the picture can disappear. This “cliff effect” means that if you watch analog TV stations that have static and distortion, you may have to adjust or upgrade your antenna system.
  
• Simple indoor antennas provide minimal performance that may not be suitable for your location. If you are unable to obtain satisfactory DTV reception with your current indoor antenna, you may wish to obtain an indoor antenna that includes features for better reception of UHF signals, as well as VHF, and/or an amplifier to boost the received signal (often referred to as an active indoor antenna).
  
• Generally, an outdoor antenna will get better reception than an indoor antenna. However, the performance of outdoor antennas can degrade over time due to exposure to the weather. If you are having problems, check for loose or corroded wiring, broken antenna elements and that the antenna is pointed in the right direction.
  
• Try to keep the length of wire between your antenna and digital-to-analog converter box or digital television as short as possible for best reception.
  
• “Splitters” that are used to connect a single antenna to multiple digital-to-analog converter boxes or digital televisions reduce the amount of signal available to each device. If you are having problems, check whether reception is improved without the splitter. In some cases an “active” splitter that includes an amplifier can solve the problem.
  
• If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” Consider using an “attenuator” or removing amplifiers to improve your reception.
  
• If you decide to replace or upgrade your indoor or outdoor antenna, many types are available from electronics retail stores at a variety of prices. Websites such as www.antennaweb.org provide information on the locations of broadcast towers and the types of outdoor antennas appropriate for the stations you wish to receive. If you need assistance with upgrading your antenna system, check with a local antenna retailer or antenna installer.
  
• To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.

Your question is confusing. If you have cable, you don't need a DTV converter box.

If your cable company has switched to digital cable, they will provide you a box, and the cable should go from the wall into the box, then into your TV.

If you don't have cable but instead rely on an antenna, then the wire will go from the antenna into the DTV box, then from the DTV box into the back of the TV. If you're using a regular coaxial cable to go from the DTV box into the television, the TV should be set to channel 3. If you're using the red-yellow-white RCA wires between the DTV box and the television, the TV must be tuned to "Aux," "Line In," "Input Select," or whatever it's labeled on your particular set.

Try the $40 RCA DTV Tuner/Converter from Wal-Mart. Connect your existing VHF/UHF antenna (if you don't have one, Wal-Mart sells them too) to the antenna input on the back of the converter and the converter to the antenna input on the back of the TV. If it has only twin lead antenna inputs instead of the standard coaxial type, you'll need a simple twin-lead/coaxial connector, which is about $5. Tune to VHF channel 3 or 4 (set your converter switch correspondingly), turn on the conveter box and follow the onscreen instructions. If you see static, use the automatic or manual fine tune control until you see a clear picture of the menu screen.

If you're not on cable or satellite, you will need an antenna to get off-the-air reception. This TV does not have a DTV tuner, so you will also need the converter box. Depending on how far you are from the broadcasters' transmitters, you might be able to get away with an indoor antenna. Or you might find that you get few channels with the inside antenna and then you'll need something outdoors. There are a number of styles to choose from.

The antenna hooks to the converter box, and the converter box then goes to the TV. It can be hooked to the TV's "ANTENNA" connector. This should be covered in the set's manual where it shows you how to connect a regular antenna. With the box, your TV will always stay on channel 3 or 4 (depends on how you set up the box) and you'll change channels on the converter.

You can also connect the converter to the TV with audio and video cables like you would a DVD player. Most of the "coupon-eligible" converter boxes include direct video and audio output jacks. This gives you better picture and sound quality than by hooking it to the TV's antenna input.

Hooking up a converter box is like going back in time to when cable TV was new and you had to get a converter box from your cable company. Same way of hooking it up. Hope this helps!

The antenna ports on these receivers are only analog pass thru's they will not convert to digital.

Is it possible to record TV programming on a VCR when using a DTV converter? h1 = document.getElementById("title").getElementsByTagName("h1")[0];h1.innerHTML = widont(h1.innerHTML); Hi,

I had the same problem and found this answer that worked for me. Hope this does the trick for you.

Simple stated, your VCR must be set to channel 3 also. Check it out.

1. You must have the VCR tuned to record on channel 3.
2. You must have the VCR connected to output signal of the DTV converter box. In other words, the converter box must be connected between the antenna and the VCR. So, the likely configuration you would use with a coaxial cable is antenna to DTV converter to VCR to TV.
3. You must tune the DTV converter to the channel you want to record prior to recording. The VCR won't be able to change channels on the DTV converter.
4. You will be able to use the timed record function on the VCR but you must adhere to steps 1-3.

If this sounds freakishly familiar to recording on a digital cable or satellite set-top box, you are right. It is exactly like recording a signal from a digital cable box or satellite receiver. While it may be inconvenient to perform the steps above, at least the option still exists to record on a VCR while using a DTV converter box.
Disadvantage of DTV Converter: You will lose the ability to watch one program and record another with the DTV converter. Sorry for the bad news.
The reason is the tuner. The VCR tuner is useless with digital except for recognizing channel 3. The digital converter is a single tuner item so it only receives one station at a time.

Good Day;

Look in owners manual pages 28-35, pay special attention to page 31 and make sure the antenna is connected to ANT-DTV input. Good Luck, big IRISH.
