Well first thing to do is this the only tv thats connected to the cable?
if it the only one
i would call the cable company and have them up the db level.
if you have more than one, you'll have a splitter that splits the cable that could be causing your problem, change it out will a new lower db one.
another thing could be happening is the cable connector on the end could be failing so have the cable guy replace all those too.

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.

Why all my cables channels not working

if you are using coax cable to conn cable box to tv, be sure to use the analog ant conn on back of tv, and there is a switch on the back of the tv for selecting channel 3 or 4, for cable box use. be sure to turn tv to the same channel the switch is selected to, and always use the cable box to change channels/ programs, not the tv channel selector.

How to tune to tv channels

There is a switch [tv-vcr] somewere in the front.When pressed to tv, you can change the channels FROM the vcr.You will need an "air wave" ANTENNA signal because the cable box individual channels cannot be seen when you place the switch to tv.Now if you have a cable box connected properly and turn that tv-vcr switch to vcr the individual CABLE BOX CHANNELS will show through the vcr.
p.s. There is a small switch (someware in the back of the vcr & the back of the cable box,dish box, etc., etc.) ch.3 or ch.4 and the VCR have to be on the same INPUT channel as the box.

Unable to get cable channels past channel 33.

Your problem is likely not your TV. It's due to the signal being provided by your cable company. I suggest that you contact the cable service provider which you are using and advise them of the problem.

Cable box, digital service, channels not appearing

connect the RF lead from the wall to your cable box then out from that to your dvd then out from your dvd to your tv. now connect a scart lead from the cable box to AV 2 on the DVD then connect AV 1 on the DVD to your TV if you have a second scart on your tv connect that to the cable box. NOW on the DVD select AV2 now whatever is on the cable box will be recorded onto DVD/VCR. Put the DVD recorder into VCR mode and set it to auto tune all the Digital Video Broadcasts. You cannot physically tune the cable boxes own channels into the DVD via RF it has to be via a scart.

VCR tuner cannot tune in my cable channels

It is working as designed. The purpose of your cable box is to take in a wire containing all of the possible channels you might watch, and then extract *one* channel, and force it to appear as channel 3. If you connect the cable directly to the VCR, then the VCR's "tuner" (ie, channel selector) has an opportunity to extract any channel it wants. But... as you point out, your VCR won't be able to "see" any of the digital channels. So... if your goal is to be able to watch any of the digital channels, the signal must pass through your cable box, which will put the selected channel on channel 3. There is no value in going from the VCR to the cable box, since the VCR's tuner will have already filtered out all but one channel. It would be helpful to make a list of what your useage goals really are, since there are so many different ways to hook these things up. Are you interested in: - watching digital channels? - recording digital channels? - watching one channel while recording another? - using higher quality video signals (composite, s-video, component, etc) rather than RF (ie, channel 3) And so on. Keep in mind that you have *three* tuners: Your cable box, your VCR, and your TV. It sounds like only your cable box can tune in the digital channels. If your cable box puts out any non-RF signal, then the best choice would be to go: Coaxial Wire -> Cable Box -> Video Connection -> VCR -> Video Connection -> TV, with the VCR and the TV both set to "video". Then you would only use the cable box as a tuner, the VCR would only see the tuned channel (via video in), and the TV would see the same channel (or whatever tape you are playing) on its video input.
