Keeps cycling through channels

I have my tv attached to my cable box. It was unplugged and not used for 1.5 months. Now it keeps cycling through the channels. I will set it to STD and TV in the menu. It stays for approx. 5 minutes and then starts cycling again.

SOURCE: Constantly flashing "Not available"

I have the same TV and had the same problem. It's due to a failure in the front-panel buttons, which are very sensitive. Mine got so sensitive that they were registering presses all the time, even when nothing was near them.

Since I never used the front-panel buttons, I solved the problem by opening up the TV and disconnecting the front panel from the rest of the TV electronics. This was somewhat difficult to accomplish due to the fair bit of TV disassembly I had to do to get to that connector. After I put the TV back together, the "NOT AVAILABLE" problem was solved, but somehow I had damaged something else--the tuner, composite, and S-Video inputs lost their color and now only show up black-and-white. (Luckily, I only use the component video inputs, which were unaffected.)

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

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.

Digital channels are not working


If your TV is connected to a "cable" box, e.g. you're using cable TV ... then it is the cable TV box that determines what you can get (based on your cable subscription). Yes, I know that some cable TV and satellite TV service providers will only deliver HD digital channels when you pay an additional (monthly) fee for HD digital channels.
If you plug the cable directly into your TV (i.e. not use the cable box), you may be able to do a channel scan on your TV, to pick up the digital channels ... but you will loose the convenience of using the features that your cable box provides .

RCA F19421 Stuck on video since switched from dishnetwork to cable


Some RCA TV's have a "video" option that requires you to use the original remote control to cycle up or down the channels.
Also, try unplugging the TV's from the power receptacle for 30 minutes....some times, that will cause the TV to reset.
With the power cord unplugged, manually push the power button on the front of the TV to discharge all capacitors.
Ensure the 30 minute is complete before plugging it back in.
Let me know if this works.
Thank you!

My insignia tv shows a NO DATA BASE error on screen. How do i fix this.


Try these tips:

Connecting your Cable box through Coaxial to the TV.
1- Turn on the TV and the Cable Box, secure all the coaxial connectors.
2- Press the "TV" button to be sure you are in the TV mode.
3- You need to set the TV in a specific channel for receiving the signal from the Cable Box, usually they are channel 3 or 4. Please press in the TV's remote those channels numbers and check if you are receiving signal about the Cable Box in any of them.
4- If you do, afterwards remember to continue using the Cable Box remote to change the channels instead of the TV one.

Connecting your Cable Box through RCA to the TV
1- Turn on the TV and the Cable Box, secure all the RCA wires.
2- Press the "TV" button to be sure you are in the TV mode.
3- Press the "Input" button to go to AV1 or AV2 depending where the Cable box is connected.
4- You should be receiving signal instantaneously after you have changed the Input and keep using the Cable Box remote for changing the channels.

TV Stuck on 1 channel


We would be happy to help get that fixed right away. The first thing we want to ensure is that all connected equipment is on. We want to then check what type of cable was used to connect the TV to the receiver. If you are using a Coax Cable to connect the receiver to TV1, check the receiver's back panel for the output name. If your receiver has a "TV CH 3/4 out": Tune TV to channel 3 or channel 4, back if it is labeled "Home Distribution": Tune TV to channel 62 or 75. If using non-Coax (RCA, Component, or HDMI) to connect receiver to TV1, cycle through the inputs until picture appears; Most TVs have a "TV/Video", "Input", or "Source" button. If we are still not getting a picture then unplug receiver for 10 seconds then plug it back in, this will reset the receiver, then try cycling the inputs again.


We hope these steps resolve the issue. We want to thank you for being a valued DISH Network customer!

Have cable tv and wanting to tape a certain channel


I would suggest that you disconnect the VCR from any signal source. UNPLUG the VCR from the power source [a/c] for at least one hour, more if possible. Before you are ready to plug the machine into a/c attach an antenna to the antenna INPUT, the VCR output goes to input of tv. [ DON'T attach cable box, or any such machine to the input of VCR.] Plug vcr into outlet and turn ON. Place TV-VCR switch on TV. [no remote control??] Change the channel MANUALLY, one channel at a time. If you see tv stations as you change the channel [KEEP changing until you have reached the " end of the line " of broadcast channels.] then you are good.Connecting the vcr to a cable box[ANY KIND!] you can only RECORD through the vcr what you watch on cable.
