Question about Vizio Televison & Video

1 Answer

Vizio dtv "scan error"

Even after a factory reset, a "hard reset" (unplugging the TV and pressing the power button for 30 seconds), and scanning with the TV cable disconnected, an auto scan (with the source set to cable) results in a "scan error" after about 70% complete. A manual scan, with the scan limited to channels 1 to 92, completes successfully, but doesn't find all of the channels that are available. A manual scan that includes channels 93 or higher always results in a scan error. Either auto or manual scanning using an OTA antenna always results in a scan error. And finally, after finding channels using the 1-92 manual scan, the found channels don't display after the TV is turned off and back on.

SOURCE: Not able to scan for digital OTA channels on a JVC LT-32X667 LCD

Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.

SOURCE: Hitatchi 42HDF52 only receives channel 5 and 6 on analog RF input

If you have tried autoprogramming and have found nothing it may be a bad tuner. Is your VCR is hooked up via coax or into a video input? If it is hooked up via video and is working but the coax connection direct isnt it will be a bad TV tuner. Easiest cheapest fix is to use you VCR to change channels or get a Digital Cable Terminal from you cable provider and hook it into video or compnent.

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.

I forgot my password


Reset the modem by removing the power cable from the back of the modem for a full 30 seconds and plugging it back in.


This is sometimes referred to as "power cycling" the modem, and is a good way of clearing network timeouts and other problems that can appear on modems that have been running continuously for some time.


Reset the modem by unplugging the power cord from the electrical outlet or surge protector into which it is plugged.


This is a good alternative to removing the power cord from the back of the modem if it is difficult to get to the modem because of its physical location. Count the full 30 seconds and plug the modem back in to complete the reset.


Reset the modem by pressing the reset button the back of the modem.

The button itself is recessed into a hole to prevent accidental resetting, so you will need a pen or some similar thin utensil that can fit inside the hole.


Press the pen into the hole until you feel the button depress and then let go.

This is sometimes called a "hard reset" or "hard reboot," as this will restore the modem to its factory default settings


Hope this helps

Carlos, we have been doing the hard reset for a while already... more than 30 seconds... to no avail... still no blink and not yet resetted.


Are you trying to do 30/30/30 reset??

THIS WILL RESET TO FACTORY

You have to do this.

THere is in the back a reset button.

With the router on.

NEVER RELEASE THE RESET BUTTON UNTIL FINISHED.
1. HOLD THE RESET BUTTON FOR 30 seconds by watch
2. PULL OUT THE POWER CABLE while still holding the RESET BUTTON for 30 seconds.
3. WITH THE RESET BUTTON STILL PRESSED plugged in the power cable and continue holding for 30 seconds.

4. Then release RESET.

Hope it works.

God Bless You!!

TV does not recieve a remote


Hey, Have you tried to power cycle your remote? That may work, do the TV too. I'll give ya the steps, just follow them and you should be ok. I'll throw in a factory reset as well, but if you're not using a cable box you will have to run another auto scan. anyways start off by unplugging the TV and removing the batteries from the remote control. Let them both sit, you don't have to let the remote sit really, but I do for good measure. You have to let the TV sit for a minimum of 5 minutes. at the end of 5 minutes, you have to find the physical power button on the TV, this means NOT on the remote, but on the TV itself, you have to find this power button, and you have to hold it down for 1 solid minute. Again, any time you can do something extra for good measure, it can't hurt, so if you want to leave it unplugged for 10 minutes and hold the button for 2, go for it, it may help. After you're done with that, power cycle the remote control. Being that your remote seems to be haywire, go ahead and press every single button, this means channel up and down, even if they're on the same button, every one from the top to the bottom, 5 times with no batteries in it. Then hold down the power button on the remote for 30 seconds. Then replace the batteries, preferrably with new ones. This completes the power cycles for both the Remote control and the TV. Now, before plugging the TV back in, we have to do the factory reset. Again, hold the power button on the actual TV, and then, while holding down the power button, plug in the power cord, wait for a couple of seconds, and then release the power button. Wait for a moment, and then turn the TV on. This completes the factory reset.

The reason for all of this, is, power cycle the remote to drain it's capacitors and reset it, power cycle the TV incase the Remote sensor is affected by a static electricity build up. Factory reset incase any settings may have caused this. Hope this helps.

Reset to factory default


The router's admin page is http://192.168.1.1 or http://192.168.0.1 and the default password should be either "admin" or "password" without quotes. There should be a choice under "Setup" called "Factory Reset". That will erase the settings and reset it like new.

Alternatively, you can follow the procedure as given below on all the brands I've tried (Belkin, D-Link, Linksys)

1. hold the reset button for 30 seconds (don't release)
2. unplug the power (still holding reset) for 10 seconds
3. plug power back in (still holding reset)
4. hold reset for another 30 seconds - the lights will usually begin flashing in some odd pattern
5. release the reset button
6. wait 1 full minute or until the lights stop flashing
7. unplug the power for 10 seconds, just to do a reboot
8. verify the settings (e.g. SSID) are back to the defaults
