If you have a good cable signal connected to the TV and it receives channel 50 nice and clear but all lower channels have nothing but snow, then the tuner is defective and needs to be replaced. This is quite an easy thing to correct. Sometimes resoldering all connections inside the tuner will bring it back to life, but in either case the set should be serviced by a qualified tech.

Channel three is missing


Hi pasu, Normally if you can get/program Chs 2 and/or 4 as well the other channels, then Ch 3 should also be programmable. If this is not possible, perhaps you can try to manually program by selecting "03" and add to the memory "+" in some brands/model. If this is still a no go, perhaps you should seek the services of qualified professional since this would apparently be an internal software problem. You can also try a hard/full reset by unplugging the TV from the mains for couple of hours or as prescribed by your TV's user manual. If the TV has Video input features, a possible temporary work around the TV's Ch3 problem is to use the Video1 or the Audio/Video INput of your TV and use an old VCR to connect to your cable box. Remove the coaxial cable from your cable box to your TV and connect it to the RF/TV INput of your VCR. Use a 3 way RCA to RCA connector (usually Yellow, Red & White) to couple the Audio/Video OUTput of the VCR to the Audio/Video INput of the TV. Select Video mode in your TV (so it doesn't matter even if you cannot program Ch3). Power up your VCR, select Ch3 in your VCR's tuner. I assume that to select channels you wish to view, you use a remote and channel selection is done in your cable box. What worries me is "...went to a fuzzy black and white screen..." which is indicative of another fault. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

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.

We have direct tv, the other day while attempting to format our mitsubishi tv from the direct tv remote something went wrong and we lost about 20 channels from our regular and direct tv. Now when we swtich...


I would start with the DirecTV unit first and set the resolution back to 480i. This can be done in the menu or with a button on the front of the receiver, all modes are shown on the front of the unit. It's not uncommon to get that message when using the DTV input on MITS tv's, it's just a formatting glitch...but a bit annoying. Your set may not decode 720p resolution so I suspect those channels that broadcast that format may be your problem.

I bought a Sanyo DP46849, lcd tv, 1080. and I'm getting a fuzzy picture. It helps when i put my cable receiver on hd channels, but even my blu-ray looks better on my 720 plasma???? any suggestions, I...


I gather from the information given that you are getting the proper signal from the cable receiver but there may be a settings issue with the LCD TV. If the 720 plasma is giving good performance then it has to be settings on the lcd .
I would review the instruction manual to see if you have over look something that is a proper cable select ( hdmi or vga).
If you have selected vga you will not get a clear picture in that mode. HDMI is High definition which works properly with 1080P mode. If you have further issue the manufacturer troubleshooting or Knowledge base will give answers also.
1. check your HDMI cables make sure they are properly seated in the input ports
squarely not at an angle.
2. If you are using a cable receiver check the connection there. Make sure you have the proper cable for your receiver to the TV
3.check channel to see if you TV is selected for channel 3 or 4 as recommend in the instruction manual
4. check the V-chip setup it may be blocking certain channels
5. check you picture modes each channel can have desire picture setup modes.
6. If you are using rca cables you may not get the proper picture as you would with HDMI cable that are specially designed for High Definition TV

Limited cable channels


There isn't a software upgrade available for your TV yet. So, the TV has the latest software right now.

I would try making the TV search for more channels.
Press Menu on the remote,
go to SETUP,
then go to CH SETUP,
then make sure the AIR/CABLE option is on CABLE,
then go to CH SEARCH and select " Analog & Digital Search Start ".
The new channels should show up after the scan is done.
If this doesn't work, the TV may need some type of new converter/cable box from the cable company.

If you need a copy of your manual, you can go here:

One channel fuzzy


Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.
