Televison station won't scan


If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.
This video shows troubleshooting steps to use when a "No signal" message appears.

How do I get my rca truflat tv to get out of mono?


Hello
Press the MTS on the remote control handset to select STEREO, MONO or SAP. All the options will be available only when the current TV channel is broadcasting that option. Channels will not always carry programes, that have all MTS options. If "STEREO" appears on the screen when you select a channel means stereo sound is available with current programme. You can hear sound from both speakers. If broadcast is not strong and clear, stereo sound will not be available. Press "MTS" button to change it to "Mono". This will eliminate the noise. If "MONO" appears on the screen when you select a channel, stereo effect will not be availabe, even though you have set it to stereo. If "SAP" appears when you select a channel 'Second Audio Programe' [SAP] broadcasting is available for that programme. Press the "MTS" button to 'SAP' and you can hear that programe in different language or some other kind of audio.

Remote to Insignia Digital converter box will not do anything but turn unit on/off, although the light does flash when buttons are push - nothing happens.


Well, try it two different ways, as follows: But be sure that the tv-channel that's selected for tuning will be identical to the "output-channel" which you'll then select for the Insignia converter-box. So, if you first select Channel 3 for tuning the tv set, then you must later select Channel 3 on the "Output Channel" choice for the Insignia "set-up" menu. Similarly, if you first select Channel 4 for tuning the tv set, then you must later select Channel 4 on the "Output Channel" choice for the Insignia "set-up" menu. Be consistent! If you find that the Insignia menu-screen does not subsequently appear after tuning the tv to Channel 3, then start-over with Channel 4 as your proper tv-tuned station to initiate the pop-up screen for the Insignia menu.

Now, here's an example that assumes Channel 3 is the proper tuning-station for your tv-set within your particular region: You will first tune your tv-set itself (by means of its handheld tv-remote) to Channel 3. Be sure, however that your Insignia converter-box is turned-on and properly connected to your tv-set and antenna.

On your tv's hand-held remote-controller, you should find a button that serves as its "input selector" -- with a typical descriptor such as "Input" or "Line" or "Video/Antenna." Press that button, and enter successive channel numbers until you get to Channel 3. You may need to press the digits 03 to signify Channel 3. The tv-screen may be colored bright blue at that point.

Then, as you switch to holding your Insignia remote-controller, press the "Menu" button. (Please note that you will need to press hard and firm upon the buttons of the Insignia hand-held in order to get proper responsiveness; a quick touch of the button will not be effective.) After pressing the "Menu" button, the Insignia menu should now appear on the tv-screen. Now, you need to use your Insignia hand-held remote-controller (not the tv hand-held remote-controller again) to travel through the menu-screen to the "Setup" feature. Then, select "Output Channel." Proceed to select Channel 3 -- which will then be printed for you next to the Output Channel feature. Finally, under the same Setup menu, go to "Auto Tuning" -- which will commence a complete scan of all available channels.

Remember, if tuning by Channel 3 is inappropriate for tv-tuning within your particular geographic region, then repeat the above process by substituting Channel 4.

When you are done, you will rely almost exclusively upon the Insignia hand-held remote controller. You do not especially need to use your tv hand-held remote-controller again.
However, be sure to avoid standing in front of your tv-set to change channels by buttons or knobs upon the tv-set itself. Tuning again upon the tv-set itself will negate your prior tv-setting for either Channel 3 or Channel 4 -- and thereby sabotage your working set-up!

I myself incurred chronic anxiety yesterday (June 13), as I was stunned that the Insignia menu-screen did not appear immediately when I pushed "menu" on the Insignia hand-held.
The only buttons that worked on the Insignia handheld remote-controller were the Power-on for the converter-box and the Power-on for the tv-set.



(continued next page)



Because my expectation had been this process would take just a few minutes, I was deeply frustrated and impatient. However, I recognized that my apprehension of impending loss was absolutely appropriate as emotional "signal-processing" for me personally -- in contrast to my formerly high expectation of immediate fulfillment, completion, and gratification. Instead of my intention for quick success, I faced the stunning dread that the Insignia box had become defective or that I'd fail to ever figure-out the problem. I would not have been so impatient if I hadn't expected immediate success for the set-up.

I rejected the slogan that "I just want to get this over with!" I rejected the option of stomping upon the Insignia box! Amidst my hour-long anxiety, I summoned "Courage" -- a mode of patience to accompany my internal "quivering." I did a Google search.

From this Fix-Ya web-site and other troubleshooting sites, I had strong clues that improperly setting Channel 3 or Channel 4 was a primary culprit for the failure of the Insignia's menu-screen to appear. When I finally succeeded, my anxiety dissipated quickly with a temporary relief. But then came the anger that the Insignia "User Guide" had not been clear to explain the process. From that aftermath of outrage, I decided to promptly compose this protocol to assist others who have been similarly tormented -- perhaps to the extent of incorrectly believing that the Insignia converter-box was a defective product requiring prompt replacement.

Cant get mono off tv screen ..


The TV set itself will probably have a button that is marked either "Video," "Input" "Source" or "TV/VCR" - I would need to have your exact television model # to be sure. Make sure the cable box is on. Press the Video/Input/Source/TV/VCR etc button and see if your cable picture reappears on one of the source channels. If your television is connected to the cable box with a standard coaxial cable, then Ch.3 or Ch. 4 would be the right choice. If you have a digital cable box, however, the cable is probably going to be on an auxillary channel. If you give me the exact model # of your TV, and the type of wires that run from your cable box to your TV, I can give you more precise instructions. Good luck!

Black box appears on tv screen


Check to see that you don't have any channel locks or parental parental permission measures deployed. If so remove them, this includes V-Chip, and Parental lock out on the remote, and check your TVs menu items. What channel are being affected by this problem? Give channel number and channel type.

Cannot change channels in digital mode


Solution that worked for me:

Beware: Although the process should be safe, it technically voids your warranty.

Enter the service menu:
1 - turn of tv with remote
2 - press and release in the following order on the remote: Info, Menu, Mute. Make sure remote is pointing at the tv
3 - turn on the tv from the remote
4 - you will see the service menu. using the down arrow on the remote select the Reset option. Using the right arrow button at this point will do a hard reset.
5 - Wait a few seconds, turn TV on
6 - you will have to rescan analogue and digital channel but it should be working now.

SAP - I can't get my new TV out of Mono and into stereo.


Are you using a cable box sush as a Comcast cable box? If so then the volume control within the cable box is most likely not high enough for the TV to detect a stereo pilot signal. The Comcast remote (if thats what you have) still is programmed to operate the volume within thier box, the volume display will be at the top of the picture and it will be in white. Turn it up until the word "stereo" appears. then leave it at that setting and use your TV's volume control only.
