Question about RCA HD52W56 52" Rear Projection HDTV

1 Answer

Programming digital channels

Have a 52" RCA HDTV, hooked to cable from the wall, no cable box, plugged into the analog (bottom) plug on the back of the tv.  We are unable to program any digital channels, which we know are available from our cable company (Mediacom).

Have followed all directions from the manual from the tv.  Any suggestions that we might be missing when programming the channels?

Re: programming digital channels

The problem is not with your TV. You need a digital box to unscramble the channels.

Why all my cables channels not working

if you are using coax cable to conn cable box to tv, be sure to use the analog ant conn on back of tv, and there is a switch on the back of the tv for selecting channel 3 or 4, for cable box use. be sure to turn tv to the same channel the switch is selected to, and always use the cable box to change channels/ programs, not the tv channel selector.

Does the RCA TV model D52W20 have a digital tuner? or will I need a cable box to watch TV? At our location they just switched the signal. we just had a tube TV with the cable line in the back and up till...

Greetings Pete - No, your display is what is called HDTV ready, meaning it needs a separate tuner AKA set top box.

You need to get the cable box, plug in the component video cables into your TV (usually provided) and plug in audio cables and you're viewing HDTV. See below:


Happy Viewing!

Before you bought your new TV, was the cable connected to an older TV, and was it working?
When you say you screwed the cable connection to the antenna input, did the cable come directly from the wall, or did it go through a cable box first. If it came through the wall without a cable box, it's possible it's not an active cable account, and you're only getting over the air signals for your local channels (and nothing through the cable). Or, your cable signal might have been analog only, and with the transition this week to digital TV, maybe you're no longer getting the channels broadcast properly.
If you are a cable subscriber, then this problem should be reported to the cable company, and they can do further testing to see what's wrong with your signal.

Hd channels not showing

Your tv has a input named COMPONENT to make work this input you need three RCA conectors (RED GREEN BLUE) plus two audio RCA Conectors red and white. If you have another set that can be plug in in this input and that set (dvd recorder, in ex.) has a digital tuner then you got it, But the Magic about the decoder box is that only cost 40.00 +- dllrs and send the signal to your antenna connector or RCA analog conector. Good luck!

No digital channels

This TV is not able to understand digital channels because its tuner is not able to find that band, it works only in analog channels. To be able to get HD channels is needed a decoder box that has digital tuner build in. for a tv to understand HD Channels with analog tuner is to us to try to speak at the same time different languages.

RCA D56W20 picture problems

More information is required to properly troubleshoot this problem. How is your television connected when you are watching HD? Do you have HDMI for this, do you have a satellite or digital cable box? For analogue are you using regular coax antenna (cable TV), or are you going through a cable or satellite box?
This could be related to the aspect ration setting. perhaps you ahve changed your aspect ratio from 16:9 to 4:3 or some other setting. If you are connected via HDMI, then the digital signal may be "normalizing" your picture during HD, but reverting back to the other setting.

Check you video settings very carefully. HD televisions are very difficult to tweak properly.
