I purchased a Insignia NS-LTDVD19 with a Digital ATSC tuner mainly because I did not want to go through the hassle of a converter box and the sales guy at the store said that this TV will automatically pick digital signals, but now when the TV stations have shut down digital my TV is receiving only 1 digital channel, when I called Bestbuy they said that though I have the tuner I still need a converter box to receive these digital signals. How far is this true?

The Insignia NS-LTDVD1 contains both an analog and digital TV tuner. The BestBuy sales clerk is wrong, you will not need a converter box for your TV.

Your problem might be with switching from the analog tuner to the digital tuner. You can do this by pressing the input (sometimes called "source") button on your remote, and selecting "digital tuner" or "ATSC tuner". You will then need to do an auto channel scan, which will tune in and set the digital channels you can receive into the tuners memory.

Do you have an antenna connected to your TV?

Have the same problem here, with the same model [actually the Insignia "NS-LCD19"]; tried the "input" selection, applying "video1 composite" and even the "HDMI" option, but was still not making any progress.

Like Jay has stated you don't need a converter box. This TV includes a cable tuner and an over the air tuner. Make sure you switch through the tuner selector until you are on TV and not cable. You can scan for channels from that point and get the OTA DTV stations programed.

Ralpha, Welcome to the DTVUSA Forum. You want to change the tuner not the input. Go into the setup menu and change the tuner settings to TV.

Thanks for the tip 1inxs. I had tried the very thing you just mentioned [applying the "input" function of the TV remote control], and for a minute, I was able to get a few more channels, actually clear ones [about 4 or so; I don't have cable TV], but then I suddenly seemed to have lost them shortly thereafter. This urged me to click on the "menu" function of my TV's remote control, and select the "DTV signal" option under the "Setup" sub-menu, to see what's going on here. A meter of some sort is thereby displayed, with a pointer treading back and forth between the "weak" and the "normal" segments of the meter. What do you suppose is the problem here?

Your issue sounds to be an antenna problem. Do you know how to use TV Fool to get the direction for aiming your antenna? Click on TV Fool and enter your address. It should give you an idea if the antenna needs adjusting. Copy the URL at the top of the TV Fool screen after your information is input and paste it in your reply post back here.

Well, here is the list that was generated from the information I provided in that "TV Fool" link: TV Fool

I have now lost all channels. Just to be clear, under the "input" function of the TV's remote control, does one select the "video 1 (composit)", "video 2 (S-Video)", "video 3 (component)", "video 3 (VGA - computer)", or "video 5 (HDMI)". I gather the two logical options in my case were either "video 1" or "video 5", and If memory serves me correctly, it was under "video 5" that I was able to just momentarily receive the aforementioned additional channels. A quick head's up will be appreciated.

Rapha, what kind of antenna are you using? A lot of your stations are VHF and less then 20 miles away, though very attainable with a good indoor UHF/VHF antenna.

Nope; I don't have basic cable. I don't have a "indoor" portable or else roof antenna, if this is what you were referring to earlier. All I have at this point, is the co-axial jack on the wall, which I connect to the co-axial jack on the back of my TV with a cable with a 75 ohm connector. Like I said, I did momentarily receive a few seemingly high resolution digital channels, but then for some odd reason, I simply lost them shortly. Now, I don't get any signals.

If you press the menu button on your converter box remote, does it pop up the menu?

Yeah, I did not get the converter box, because well, my TV set is already digital, with an integrated ATSC tuner and an HDMI input. A digital TV that requires a converter box for digital channels would be self-defeating.

oh, sorry, of course it would be.

I'll just throw in my $.02 here, maybe you'll get some more help this weekend since not many people are up this late,

but you're going to need a UHF/VHF antenna. I'm not sure how you ever received any channels without one, other than connecting to that 75 ohm outlet on the wall must have some how gotten you by for a while.

The main thing I'd focus on for now is, making sure you have your TV set to the correct input and trying another rescan. Then definitely buying a antenna or trying a set of bunny ears type antenna (if you have an extra one).

Interesting; because for some reason, I have been able to get channels without the UHF/VHF antenna for quite some time now. And indeed, as I noted earlier, for just a brief moment, I even had access to a few [quite clear] digital channels...and again without said antenna. So, if I got you correctly, you are saying that a digital TV set as I described, still requires a VHF antenna?

If I get this right you are just hooking to a jack on the wall. That jack was probably a cable jack that is no longer turned on, since you said you you don't have an indoor or outdoor antenna.

The problem I surmise from this. You don't have an antenna. That is the problem

Your signals at your house are very strong and it appears a simple indoor antenna will work.

Go to the store and buy an antenna like like this with "ear" and a loop.

Like this
Budget TV Antenna - RadioShack.com
or this
Philips MANT075 Indoor VHF/UHF/FM TV Antenna - RadioShack.com

Hook the cable from the antenna to the matching connector on the back of the TV that says RF or Ant or Antenna input.

Then select the input that is TV over the air.

Then find where you add channels or scan channels.

You should see a LOT more channels.

Piggie, I'm beginning to think you all may be right about the antenna thing; it appears that I received a couple of digital channels again, lowered down from the previous ones I was able to receive *only momentarily*. Well, I'll go and get me the recommended indoor types later today and see what happens from there. Thanks for the help. So long.

If you buy too fancy of an amplified antenna, you may make things worse. Buy a cheap rabbit ears with a loop, and don't forget moving it around and rescanning. Even if that is not enough antenna, you are only out $10 or so.
