Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

3 Answers

QUAM TUNER Does the RCA Model #D52W20B have a QUAM TUNER in it ?? My cable company wants to know because the cable company supplies HD Channels however you can only take advantage of them if you have a QUAM TUNER in your TV. Another words my cable company does not have the box necessary to give to it's customers in order to take advantage of the HD Channels and receive them. It is necessary for the customers TV to have an installed tuner that processes the HDTV channels in order to see them in 1080i on your screen. I hope someone can help me here.

I didn't realize my Sharp Aquos had this capacity. When my cable service had been switched off and came back on, I suddenly had these awesome channels of the same (NBC, CBS, ABC, etc.) which were so sharp and clear. Well recently we had another outtage in the area and the "cool channels" were gone. My cable company found out I had this type of "QAM" thing and scrambled it so I couldn't get it anymore.
Can they do this? If so, what's the purpose of having QAM? if your cable company will seek you out and nailya?

No it does not. The CATV Feed is supposed to be inputted into the ANT input and Autoprogram itself. You are going to have to go to the menu and manually hit Channel Surf or Whatever it is called on your Television. Hope this Helped.
Thanks for using Fixya!

    I slpit my cable internet and ran cable to all of the tvs in my house, I did not subscribe to television service, My older crt teles recieved 10 or 12 channels (on air stuff), My older syle lcd and plasma tvs recieved around 20 or 25 channels, and my wifes tv in our bedroom, lcd, with the quam tuner, recieves around 40 or 50 channels which include all the HD channels in amazing quality....if all my tvs had this quam tuner, I would be recieving incredible quality veiwing as opposed to subscribing to less channels for way more money.

Doubt it. We ran HD through our small CATV system using consumer grade modulators but could only get them on the AIR frequencies, as we had very limited bandwidth as we had to carry 64 analog channels plus digital HITS packages for our Motorola DSxxx series boxes. Try plugging the CATV feed into the ANT input and do an autoprogram, or tell the tv to look on the AIR frequencies when it asks if you have CATV or AIR. Worth a shot though.

If these tv is digital why I need to use a converter box to see the channels


Because it does not have a ATSC nor a Quam tuner in it. Just a regular tuner. As it says HDTV ready. This meant back when you bought it that it will receive HD when a hd cable box is used and connected to the DVI or the Component input in the back. This was a low end set at the time. It will still receive regular cable without a box.

I have a olevia 337-B11 HD-ready TV, which kind of tuner i need to watch HD TV program? Thanks


The original question seems to be for someone without cable, so Dave 1645's answer is incorrect.

What the Original questioner would be best off puchasing is a Centronics ZAT 502 HD (AKA: RTC DTA1100HD / Digiwave DTV5000HD) which is $100 and is a much better tuner than most tuners integrated into HDTVs.

The Centronics ZAT 502 HD is highly regarded on expert forums such as AVSforums.

The issue of the original question has nothing to do with QAM.

I HAVE A SUMSUNG THAT IS HD, BUT IT'S NOT HDMI,i GET REGULAR CHANNELS, BUT WHEN I SWITH TO A HD CHANNEL, IT IS ALL SCRAMBLED? WHY?


I assume you have cable. The cable HD and digital channels are usually sent in Quadrature Amplitude Modulation (QAM). The cable companies are required to send local channels in the clear but not so for any others. Regular (basic) channels may be clear or scrambled. USA many not be but HBO will be.
So you have 1 of 2 problems: (1) your TV does not do QAM or (2) they have scrambled the channels you want to see. Questions: (1) Have tried direct Over-the-Air (OTA, ATSC) reception for your locals? (2) Can you see the HD local channels on cable? (3) Are you paying for an HD box from the cable company to have the channels decoded? If in doubt contact the cable company.
Current Samsung TVs do do QAM and OTA HD. Alternatives are Dish or Direct to get satellite with an HD receiver using HDMI or 5-cable RCA. Costs are comparable but OTA wins, hands down. -Ken

I don't know how a program it, since you change digital.


So far as I know the HLN series does not have an ATSC tuner, thus no over the air (OTA) reception. You can probably still get a $40 coupon for an OTA ATSC to NTSC converter. Note that will NOT get you high definition (HD). With Dish you can get HD receivers that do get OTA ATSC both HD and SD. With Direct, no OTA AFAIK. With cable you would need a QAM tuner, not in your TV AFAIK to get clear channels as required for locals. Otherwise cable needs a Set Top Box for digital and scrambled channels although the standard definition (SD) non-scrambled channels work with your NTSC tuner. Too bad there seem to be no ATSC to 5-cable RCA or HDMI HD converters except Dish. -Ken

How do i know if my tv has a quam tuner im not


First it is QAM (quadrature amplitude modulation) and is used only on cable systems. Know that you will only get clear-QAM, this is, those not encrypted. This means only the local channels, which they are not allowed to encrypt. It will switch automatically, so if you get any HD it will be QAM. They will have names like 85-1 for digital source, not necessarily HD. Not all set-top boxes can tune digital channels--check with your cable system. You have called them? Be sure to remind them on your STB make and model, they may need to replace it. -Ken

Get closed captions on some channels, but not all, even though it is CC


RCA have choices for different methods of CC in user CC menu. Labelled T1, T2, etc. . Different selections are for different types of close caption. Tune to a signal (on your other TV) that has closed caption working.

Tune your RCA to the same signal. Change the T1,T2, etc settings until the closed caption for your signal appears.

If this doesn't work, try connecting analog video or VHF channel 3 (or other specified channel) to the TV. check CC. When TV stations, sat channels, sat receivers, cable boxes etc, convert analog video signals to HD, problems can result. Some equipment causes RCA TVs to do unexpected things with sound and closed caption.

If you use RF or video output, old analog video may look better on CH3 or video than on HD input and the CC will work more consistently. Watch HD signals on HD input, Analog signals on Video in or through the TV tuner . Many HD channels and programs are converted analog video and look poor on TV HD inputs.

Help with definition


You need an HD Tuner box to pick up the over-the-air HD channels. This TV is only HD ready. Regarding your cable company's cable box, as long as it has an HD tuner, it will be able to transmit HD channels to this TV.

Ready for nat'l digital transition?


If it is an older model (i couldn't find anything on it either), it most likely does NOT have a QAM tuner. Be aware that only the "un-encrypted" cable channels will be free otherwise you will have to buy or rent the digital box from the company to get the rest of the regular digital channels. The un-encrypted channels are like 71.2, 83.7 so you should know if you are getting those or not.

Seting up the digital seems to be a problem, tv is tuned in, put digital doesnt? samsung 42" lcd plasma


First I need to know if you have a digital quam tuner in the set? If you don't you will only get analog thru the tuner. You must use a HD box from your cable co. or sat. provider to receive digital channels thru your component input.
