Hi,
Please unplug tv from wall socket for minutes or so to get it reset, replug back in and tun it On, if still does not change channels then perform Auto Tuning/ Scan as option is available in tuning menu.
Hope these info will help you.
Thanks.

    do you mean scan for available channels?

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    Yes, scan available channels.



  • laszilagyi May 28, 2010

    it's at 76% and no channels found yet. Cable company says there's nothing wrong with the box.

  • laszilagyi May 28, 2010

    scan for channels is complete; it didn't find any and all cables are connected

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    OK, make sure that you select Cable in auto scan function because if antenna was selected, tv will show very limited or even no channel after scan mode completion.
    In auto scan option you will see Cable and Air Antenna option to select what tv channels to scan.

    Is it Vizio VF550M tv or any other model?



  • laszilagyi May 28, 2010

    it's scanning on cable, but not returning any channels

  • laszilagyi May 28, 2010

    it's a vizio 55"

  • laszilagyi May 28, 2010

    it's a VF551XVT

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    OK, please check coax wire of cable box is plugged correctly in tv.
    It could be wither coax not plugged properly or bad tuner in tv problem

  • laszilagyi May 28, 2010

    ok, cable is plugged in correctly, tv is on channel 3, but no picture

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    Is it under warranty?
    I'm thinking of bad tuner board in tv.



  • laszilagyi May 28, 2010

    still getting no signal message

  • laszilagyi May 28, 2010

    it probably is - i bought it in January

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    If tv is under warranty then please call Vizio to fix it under warranty cover, I think its tuner board need to be replaced.



  • laszilagyi May 28, 2010

    Thanks - am calling them now

  • laszilagyi May 28, 2010

    vizio said it's not the tuner board since i'm using a cable box

  • Shahid Electronics
    Shahid Electronics May 28, 2010

    Thats amazing, tuner is not getting cable box signal to show cable channels.
    OK, please call cable company to send out a guy to test cable box.
    Do you have any other tv to hook that cable box to confirm that it is providing channels correctly?



  • laszilagyi May 28, 2010

    That's what i'm going to try now. Thanks again for the help. The Vizio person said if all else fails, they'll check the HDMI port on the tv. I'm getting channels on another tv in another room, so will try swapping out the cable box to see if that makes a difference.

  • Shahid Electronics
    Shahid Electronics May 29, 2010

    Yes, swapping cable box will confirm what thing is causing problem so to fix it.
    Thanks.


  • laszilagyi May 29, 2010

    it appears to definitely be the cable box. A different box works fine with a different tv, and a different tv does NOT work with the affected box.

  • Shahid Electronics
    Shahid Electronics May 29, 2010

    OK, so tv is fine and cable box is bad.

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.

Sharp LC-37DB5U stuck on one channel. Won't respond to anything. Put in a new motherboard and same problem persists. Sound and picture are fine


I could be wrong, but it sounds like the TV hasn't gone through channel setup. You have to do this in order for the TV to "learn" the channels, assuming you are using cable. If you are using cable run channel search in the setup menu and see if that changes anything. Can you change channels by manually entering in the channel # and hitting enter?

TV (RCA model F32705) stuck on one channel


Usually the fix for that on a RCA or GE TV is to go into the menu (the button in on the front of the TV) and find channel settings and let the TV autoprogram itself. This should fix the issue.
