Stuck on one channel


Is it the tv's remote? Change the batteries
are you on a cable box? You need to use the providers channel changer. Tv is made to stay on one channel like channel 3 and the cable box runs the different channels.

Connected lg tv directly to cable wall jack. Can only get one channel. Manual scan grayed out. Ez scan does not find any channels. Main input is set to cable box. No option for just cable


Why not get a box and hook via rear inputs--not that expensive from most cable companies. If items such as the channel scan are grayed out it means something in the set is set wrong---

I can not get channels on my vizio hdtv. i have a cable cored hooked up to the tv and i can not get the channels to come on the tv screen. it keeps saying "No Signal!"


You will need to make sure that your cable is connected to the correct input (if more than one) and then enter the Menu and look for a "set up" screen and select "Scan for Digital Channels".

After the scan the TV should be fine.

I have it hooked up to the cable dvr with a hdmi


You don't need to scan for channels if it is connected by a HDMI connector, just select HDMI 1 or 2 depending which one you have connected the cable to at the rear of the TV. You should now receive the already set channels from your cable box.

Have a vizio lcd tv . can not get any channels today with the switch over to digital. i use an antenna


Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.

Suggestion doesn't seem to apply to my tv


Service menu settings and resetting if still nothings happen. Then DVD works fine and then the signal strength is 95%. Then the problem is your cable card provider. They blocked your channel this is the common problem of card deactivation. Just try this, take the cable connection and put an ordinary outdoor antenna, if still not working then the problem is in the signal board , but if it's works ok then the problem is cable card activation...

Checking the Diagnostics screen 1. Make sure the RF cable is plugged securely into the CABLE connector (not the ANTENNA connector) on the back of the DVR.
2. Tune to a channel that is having a problem and press RECORD to lock the tuner to the CableCARD.
3. Press the TIVO button and select Messages & Settings > Account & System Information > Diagnostics. Look for the number of the problem channel, and then look below it for the Signal Lock setting.

• Signal Lock: Yes means the DVR is detecting a signal for the channel. In this case, the DVR usually cannot display the channel because either the CableCARD has not been activated or during activation the card did not receive the provisioning necessary to display the channel. For more information, go to
Step 4: Determining if the CableCARD is activated.

• Signal Lock: No means the DVR is not detecting a signal on the channel. If this is happening for only one or a few channels, this channel may not be in your lineup. For more information, go to
How Do I Determine Which Cable Lineup Is Mine?

If you see Signal Lock: No, and Test Channels could not display any video on the CableCARD, use the following procedure to check the signal connections.

Checking signal connections 1. Partially eject the CableCARD(s) so that they are disconnected from the slot.
WARNING: If you remove the CableCARD(s) completely, you must take care to replace them in the same slot. Switching slots will unpair the cards; to re-establish pairing, you will need to contact your cable provider.
2. Press the LIVE TV button on the TiVo remote control. Do you see video?

• If you see video, the CableCARD activation was not successful. For more information, go to
Step 4: Determining if the CableCARD is activated.

• If you do NOT see video, go to Step 3.

3. Plug the RF cable connection directly into your TV. Do you see video? • If you see video, go to Step 4.
• If you do NOT see video when the cable feed is connected only to your TV, contact your cable provider.
4. Reconnect the cable to the DVR and try the following, in order. Press the LIVE TV button and check for video after each step.

a. Check the cable connection on the back of the DVR. Make sure the RF cable is securely attached to the CABLE connector.

b. Press the INPUT button on your TV remote control to cycle through the settings. The Input setting must match the physical connection between the DVR and your TV (HDMI or Composite, for example).

c. Press the FORMAT button on the front of the DVR to cycle through the settings. This ensures that the DVR is sending a compatible signal to your TV.

d. If you have any splitters installed, remove them and then reattach the RF cable to the DVR.

5. Restart the DVR. After the DVR restarts press the LIVE TV button. If you still cannot see video, contact the TiVo CableCARD hotline.
