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?

You do not indicate if you have auto programmed the television to get digital channels, If you are selecting a channel without a decimal point, for instance 82.3 is NBC hd in my cable system. If your cable provider does not produce these on direct cable then you can not get HD without a box. Try to Auto Program your tv in the cable mode STD format, this can take up to 20 minutes to complete scan including deleting scrambled channels. After programming try the lowest or highest analog channel like 2 or 70, channel down or up from there to see if any digital channels appear.
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.
I have the same type of TV and as soon as i figure out why it also, will not convert from analog to digital ,I can hook up to converter box get all kind of clear channels I am quickly finding out These Sets Are either minor problems or very major problems. They have over 32 different SSB tuner boards,and they all look alike but are not, hookups and connectors are not the same.
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!
Ok first I can save you some money. Take your "HDTV" antenna back. There is nothing different about the antennas needed receive analog and digital signals. If you got reception without your converter box, use the same antenna with your converter box.
Next let's see if there is a problem with the box. Hook up a television with the antenna. How many stations do you get? Now hook up the same television & antenna, but this time put the converter box between the antenna & the TV. Do not turn on the box. Now how many stations do you get? If the number is different, the box is not allowing the antenna signal to pass through. That is bad. You want your signal to pass through the box so you can still pick up stations that don't broadcast digitally. Some areas of the country will not be covered by digital stations from all major broadcasters when the changeover happens in Feb.
My suspicion is either you did not have the antenna hooked up to the converter box when you searched for channels OR you are in an area that is not yet broadcasting digitally.
I hope this helps you solve your problem. Thank you for using FixYa and feel free to add more questions here by using comments.
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.
convergence for the rca itc222 is set individually for digital and analog tuner. Most of time the set will have to be converge in service mode. as a tech i would not recommend getting intoservice mode. but the key is the the convergence has to be set indiviadually for each tuner. You could try autoconverging in digital or even manualy converging
