Re: Determining if TV has a digital tuner
A converter box is only required if you are using an external antenna (rabbit ears or rooftop). If you are connected to cable or satelite, no converter is needed. Please do not confuse a digital tuner (select channels using numbers) from a digital broadcast. The current broadcast system uses an analog signal. The changeover is to convert that signal to a digital one which will take less frequency space for the same channel. This frees up space for additional channels.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Analog to digital converter is for OTA transmission. You are using a cable system, right? If so you have to feed into your Tivo the cable output signal from your cable box and set your tivo to correct rf or video input. Since cable tuner is determining channel all you can do to record is set the channel on your cable unit and program your tivo to turn on and record the input at appropriate time..
Most of the RCA GuidePlus Gold gemstar TVs worked with analog TV signals (NTSC) only. The Guide+ information was only broadcast in NTSC signals and is no longer being provided. If you can check the date of manufacture of the TV, you can use the size to check if it had an ATSC tuner added if it was made for the US market. 37"+ TVs had to have a digital tuner in second half of 2005. 25" TVs needed to have the ATSC tuner after March, 2006. The next year all TVs had to have a digital tuner.
I hope this helps. Please add a comment with the model number of the TV, if you would like me to confirm the tuner information on your set.
(The RCA F31317 TV with Guide+ was manufactured in 2000 and thus only has a NTSC tuner.)
I'd need the model number to tell if the RCA TV has a digital (ATSC) or analog (NTSC) tuner. The mandate for inclusion of the ATSC tuner depended on the size of the TV and the year of manufacture. Small (<25" diagonal) TVs didn't need to have an ATSC tuner when they were built until 2007. The older TVs could still be sold with a "cable-ready" or similar NTSC only label. (The 32"+ TVs had to have the ATSC tuners in 2005 and the mid-size TVs had to have the digital tuners in 2006.)
For example the 27F530T was manufactured in 2003 and only has a NTSC tuner. However, the 20F424T was manufactured in 2008 and does have an ATSC tuner.
That RCA TV has only an older analog tuner, so if you're still using it for off-the-air reception you'll need to be using it with a digital converter. I'm assuming you are, since you say there's a channel number 14-3 being shown. The only way you'll see such a number is if it's coming from a digital converter, which will be sending the signal to the TV on channel 3 or 4 (on the TV's internal tuner).
There are several possibilities. One is that the converter isn't changing channels when you use its remote control. This is often caused by weak batteries, so try a fresh set. If your model of converter has channel up/down buttons on it (some do, but many require the remote for everything), try changing the channel manually.
If the converter isn't changing channels, you should try rescanning. The channel memory may have gotten cleared or corrupted for some reason. Also be sure the antenna is properly connected. With digital broadcasting, no antenna means no picture, guaranteed.
If everything else seems to be correct and the converter isn't finding any channels, you'll need to replace it. Unless it's still covered by the manufacturer's warranty or you have a replacement plan from the seller, you will need to purchase a new converter. They weren't designed to be serviced.
No,all CRT tube tvs don't have digital tuner inside.They're analog tvs.Must buy the converter box,and hook it up to get the free DTV airwave signal.Trust me,i help an elderly person hook up this exact this tv model with a converter box.Try buy the RCA model converter box,it matches with this tv model very well.
You've not given us the manufacturer, make and model number, but I see 3 analog inputs on the left and the usb on the right. This tells me the analog audio and video signals must come from a dvd or vcr or tv-tuner. You say getting channels, so I'm assuming you've not hooked up to a digital ready tv hooked to cable or dish or digital converter. THERE ARE NO MORE ANALOG SIGNAL CHANNELS ANYMORE. Everything went digital in June 2009. So there you have it. If you don't have usable information going in, you can't get it out. try it with sterio audio and video from a digital tv that is receiving channels, and I think you'd then see sterio and video out of your pc.

The digital tuner has nothing to do with the new signal you will be receiving in February of next year. The new video signal is a digital signal. The old video signal is analog. Your television receives the analog signal and converts it to what you see on television. You need a converter box to convert the new digital signal back to an analog signal your television can convert.
if your tuner is already dead replace it.because the original tuner of your TV is very expensive. the solution of your TV is converting tuner, you buy a kit name AUDIO TV CONVERTER . simply conection and and not very expensive. just plug the unit to ac line and connect the cable line to rf of your Television and its OK. im just trying to suggest my solution to you JRANDY phillipines tech
