Factory reset

this model TV may not have that factory reset as stated in this link. But I agree if there was a factory reset it will resolve this problem. this is a older model Vizio about 15 years old

This problem never got resolve, I had the same problem on the same model Vizio. this maybe firmware related but not 100% sure.

I had to replace the main board in this case.

I wonder if a complete factory reset would do the job and make certain it's set up for NTSC reception.

Re: Can't scan for channels on Vizio gallevia

Theres no tv button that cycles between the 2. The tv, choice cycles to Tv/ then component1 then component 2 then RGB then hdmi 1 then hdmi 2. Ive tried it all. It is supposed to auto scan both analog and digital and it does not.

OK... but what is the status presented on the screen with each press of the tv... NOTE: does it actually change with each depress? I am not sure there is a "visual indication" change for "TV" versus "DTV".... my guess based on the manual that was provided in the thread.

Re: Can't scan for channels on Vizio gallevia

I had a DTV scan problem on a Samsung whereby the DTV option just didn't show - turned out to be corruption of service menu when some caps went bad. Now a strange one - I have read somewhere some time back of a tuning scan problem - fix was to disconnect antenna and run a scan then connect antenna and run scan again - for what its worth!

Re: Can't scan for channels on Vizio gallevia

you have to push the tv button again... that cycles the connection between "tv" and "dtv".

Re: Can't scan for channels on Vizio gallevia

Please excuse the bad pics. I'm in a hurry on my way to work. I have disconnected and reconnected power cord as well as antenna. to reset tv . It will not work. . also there is no tv/dtv button. there is tv/dtv connection. its the same exact connection! there is no tv/dtv/ button. there is tv if you push it , it does not change to dtv. that must be some other model. as you can see there is just 2 modes on tuner. air and cable. i was showing the other screen just so you could see digital is greyed out. When I try the auto scan it will only scan analog. it will never scan digital.

Re: Can't scan for channels on Vizio gallevia

The manual has an anomaly in instructions. I would remove the antenna and turn set on for a few minutes then turn set off for a number of minutes including remove from pp. Then attach antenna plug set in and turn on. Then with remote push to select TV then push input and see if both options of TV and DTV show along with HDMI etc. If so select DTV and then go to scan menu.

A further "ah ha". this has correctly identified the issue. You are currently selected as "TV" which means the in coming connection on the coax connector is expecting to see rf coming from things like a vcr or an "analog antenna signal". You need to press the "tv" button to select "DTV" instead of "TV" (the button has a dual "switching function" to switch the coax connection switch internal to the tv).

X2...ah ha... now we are getting some place.
from the picture... you need to be one more icon over for the antenna settings information.

Re: Can't scan for channels on Vizio gallevia

Days off work again so I tried to fix tv Again it will not work.. I've used several indoor antenna's old and new. I took the mirror to help look in back to all connections. I'm connected to tv/dtv connection. if I take off the antenna the analog as well as the digital is greyed out so it is sensing the antenna. as you can see. from 2nd pic with antenna connected only the digital is greyed out.

are you sure thats the rite menu screen im sure digital cc means Closed Captioning that has nothing too do with the tuning of the tv

Re: Can't scan for channels on Vizio gallevia

I have manual. I have plugged it into the same connection it was plugged into before, the dtv/tv connection. There is no specific dtv button there is a tv button and a tv/dtv connection. The digital option is greyed out in the settings on menu which when I looked it up means it is not sensing anything is plugged in. I have to work all weekend but monday I should be able to buy another antenna and try it.

I wasn't referring to the TV side of things... there is only one coax connector on the TV... I was talking about where the "other end" of the cable was plugged into... a wall plate, an outside cable, what? IF its the same "cable point" that your were plugged into before and said you were "taking cable tv service" and now you want to use "antenna" on the same connection... something has to change at the "far end" of the incoming cable connection. Basically, how about a picture of your tv antenna that you are trying to use.

Re: Can't scan for channels on Vizio gallevia

You should be able to scan for digital channels with and without any antenna attached to the TV. You can't even get the thing to scan, so don't waste money on a new antenna.

Re: Can't scan for channels on Vizio gallevia

And THANKS! for everyone help so far! when I get another antenna on Monday I will post results.
