If no signal is received that means the problem is between the antenna and the tuner inside the scanner. You will gonna have to open it and test for shorted or interrupted parts. Check especially the solderings on the antenna plug and the protection capacitors on it - they might have been shorted by a power surge near by.

I have astron tv 14 inches. when i connect outdoor antenna the. tv screen turn black. no signal. no reception but when i disconnect the outdoor antenna it turn to blue screen.


blue screen means 'no signal' or 'signal level is too low' whereas black screen means that there's a signal. Check your antennae, do a factory reset to your unit and then try initial setup.

I have a VIZIO E552VL TV hooked up to an Over the Air Antenna and want to MANUALY put in channels NOT AUTO SCAN


Not sure if your TV is digital or analog, but I think an analog TV does not have the ability to perform auto scan, so you may be able to manually input the channels. As a kid, my dad installed a rotary antenna, and as it rotated and TV pictures displayed on the screen, dad noted the specific spot on the rotary unit; and every time we turned the set on, we just pointed the arrow on the dial on the unit to where dad noted what the channel number was on the unit, and the antenna turned toward that direction, and the pictured appeared on the screen.

Setting up antenna to television


For setting it your set you will have to connect the antenna to the back of set.
Go into the setup menu to select the input signal source.
Set the signal input to the antenna air.
Go to the scan section of the setup menu.
Scan in the channels. You can move the antenna and re-scan to try to get more channels.
Exit menu.
Now you can watch.

My Lorex SV-01-RCV Wireless A/V instructions were lost in our move and I need help with the set up. Could you please help? I can not remember the correct connection.


You should have a 2-wire cable with Yellow, White and Red RCA plugs on each end.

The Yellow line is video out.
The White line is Left channel audio out.
The Red line is Right channel audio out.

Since your RCV only has two RCA jacks use the Yellow line for video and the White line for audio.

You should also have an "F-connector for co-axial cable.
If your TV set does NOT have audio and video jacks hook that to the co-ax antenna connector on the back of your TV set.
Set the RCV for either channel 3 or channel 4 and do the same with your TV set.

The RCV unit has four receive channels which must match up with the channel selected on the CAM or TX unit.

You can scan all four channels either by auto or manual.

If you only have one CAM or TX unit it probably doesn't matter which of the four you use unless you have a computer ROUTER which interferes with one of the four channels.

If so, select the 1, 2, 3, or 4 channel which has the least or no interference manually.

I get no stations on my tv


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.
Hope it may helps:

After connecting the cable to the TV, you should scan for channels. With the built-in cable QAM tuner, you should be fine with a scan for channels.

Try another TV to make sure that cable broadcasting is coming in...is there a set-top cable box involved?

Digital Television Transition and Public Safety Act of 2005


I take it you are trying to get a HD digital signal from an antenna. If that is the case, you will have to go to the menu and have it scan for antenna signals. It should automatically pick up digital channels as you scan. There may be a box to select to prefer a digital signal as well which you should have marked. It takes some time and the channels may not appear instantly. If you dont get the channels, you may need a more powerful antenna.
