Question about Vizio GV46L 46 in. LCD Television

1 Answer

The DTV input in my GV46L stays black. Why?

The DTV input in my GV46L stays black and when I try to go to the menu the tv buttons have to be pressed hard. In the end I can't scan for channels because I can't reach dtv menu. So I'm left with a complete black screen. What might be the issue? We've had it for about 4 years. This had been going on and our costco insurance covered it, they changed some type of antenna before. But on regular TV input it works just fine.

You don't say what you are trying to input but take note that your model does not have a digital tuner on the DTV input. If you use a digital OTA antenna, the signal must first go through a digital converter or tuner before it goes into the DTV input. The DTV/ANT input is only cable ready. There is no digital tuner in the TV to activate the DTV menu.

Hi all please help, I have an LG 32ld450 with no remote so I'm using my sky+hd remote. The problem I have is that I've tried to set up a magic eye in my room but I can't get off DTV to get the right...

Your TV has menu buttons on the side. When you go in to the menus then the normal thing is for the Volume and channel keys to act as Up/Down and Left/Right. I can't tell you which will do what function; you'll have to try it, but they should work. The TV also has an OK/Select/Enter button on it so you can activate a sub menu as you navigate through.

From the side menu it should be possible to access the tuning menu. Once in there you can set up the TV's analogue tuner to receive the Sky box RF2 out signal.

As for how you change between the analogue and DTV tuners, that could be a tougher nut to crack. There's a little trick with a Sky remote that allows one to program the Help key to bring up a TV's input menu:

On your Sky remote, press TV
Now hold down Green and Select together until the red LED flashes twice.
Now press the help key
Now press Select

Now, when you press TV and then the Help button the TV should display its input menu. Pressing help repeatedly will cycle through the inputs.

Of course,m the above only really helps if the TV lists the analogue and DTV tuners individually. If it doesn't, and there's now way of accessing it through the TV's menu navigation, then you might have to just bite the bullet and go to a supermarket and buy a cheap universal remote. Check it has the TV/Radio or TV/DTV function before you buy.

I have a blue light and an orange but my tv will not come on

If you are referring to an R15 (the big box in the picture with your post), there should be 3 blue lights on the front of the DVR: one to the far left (power), a big circle in the middle, and one on the right indicating the resolution the DVR is currently trying to send to the TV. The orange light indicates that something is being recorded; either a show or something from DTV like channel listings. The orange light has nothing to do with your TV but may indicate that the DVR is downloading setup information.

As for turning your TV on, when you first get DTV, the DVR remote does not know how to talk to your TV set, only the DVR, so you have to teach the remote to talk to your TV. To do that, turn your TV on with the remote that came with it (or the on/off switch on the TV if you're a dinosaur like me) and change the TV input to whatever input the DVR is attached to - usually HDMI or Component. If you see something (a TV show, a guide, a DirecTV logo, etc.) you're in the right place. Now hit the Menu button on the DTV remote and you'll see a menu on the left that includes "Setup". Use the arrow buttons on the DTV remote to move to Setup, press Select, and then select Program Remote. Follow those instructions carefully, step by step, and you should be all set. (Caveat: I am working from memory so the exact wording might not match and I might have missed a menu level. If so, I apologize.)

Cannot change channel on my Dynex DX-L26-10a TV

Try checking the signal strength then run the scan again.
Checking the DTV signal strength
You can check the DTV signal strength to determine if you need to adjust your antenna or digital cable input. The higher the signal strength, the less likely you are to experience picture degradation.To check the DTV signal strength:
1.Press MENU. The on-screen menu opens.

2.Press < or > to highlight Channel, then press v. The Channel menu opens. The DTV signal strength is shown at the bottom of the menu.

3.Press EXIT to close the menu.

When i turn my toshiba regza on I cannot access DTV all I get is a black screen. when i press the menu setup button this comes on for about a second then goes off again to a black screen. I can still use...

Try either the "content / menu" button between the volume and programme buttons. Failing that, when the tv has been powered up from the wall socket wait untill you hear a small click from the t.v (usually about 5 or so seconds after it has been switched on) before switching it on from the remote control, have no idea why this works but the dtv has worked for me ever since I powered the tv up like that

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.

Run a channel scan on the DTV and/or TV input depending on what one your not getting channels on. This will solve your issue.

Change the input on the unit to the DTV or TV input. Press the menu button on the remote. Navigate to the tuner DTV or TV tuner setup menu. Go down to auto search using the down arrow. go right when with auto search selected. This may take a few minutes but you should have all the channels back after the scan.

Hitachi 19WDVB

Had the same problem. Digging through the manual I came across a paragraph (at the top of page 24 - DTV Features) saying "if you have selected DTV then it will only display the DTV menu. (I didn't actually select DTV - we can't even get DTV in our area, but the ASP programduring startup appears to have set it!
You have to press the Volume +/- buttons on the remote, then the Input button and it will bring up the input menu. There you can select a different input. Once I did this, I found it had both my TV channels tuned and my satellite channel!
Now my problem is I can't control on/off or volume with the Sky controller - which is why I'm trawling the forums!!
