I assume you are using a Comcast HD cable box ..... that's the only way you will be able to view HDTV. You do not need a Hitachi HDTV tuner.

My hitachi digital hdtv has always had cable hooked to it,and now i have no cable and i cant get the digital chanels to work with the antenna


The set will need a digital box to receive digital channels as it does not have a digital tuner in it--it is a very good set.

I can't get my Comcast cable channels to display on my Hitachi HDTV..how should I fix this?


A very well written question and I think you have provided your own answer.

this set uses a antenna switching assembly and they do fail. It could also be a bad tuner--note that the other owner got blu ray and such on it which are not via the coax fitting.

If your box has audio/video output jacks (like the blu ray) connect them to one of the rear audio/video inputs on rear of set and select that input on the set---box will then be used for channels but connection will not be via the coax but via that input.

If the box does not have those outputs get another--most providers do not charge for a box with those outputs on it.

If works you are just bypassing the tuner where your problem seems to be---those antenna networks are no longer available from Hitachi.

Do you have to add a converter box to receive free


You will need a converter box or a separate tuner. The TV has an NTSC (analog) tuner.

I hope this helps.

(the $40 boxes that are available are mostly SD. You should check the specs if you want a HD tuner.)

Hitachi 51SWX20B is this TV HD ready?


In answer to your question, you have an HD TV Monitor, which means that your television is capable of viewing high definition, but does not have an HD tuner. You will need a separate tuner or in the case of cable, a HD cable box. These are the only options that you have for viewing high definition channels.

I hope this information allows you to resolve this issue.

Digital Channels??


Direct from the Hitachi website - "Integrated HDTV Tuners: Hitachi's new top-of-the-line XWX series features built-in ATSC terrestrial and cable HDTV tuners to provide integrated high resolution, high-definition signal decoding." You will need a seperate HDTV tuner if you do not have cable or satellite and want to watch off-air High Definition channels.

PROBLEM WITH GETTING LOCAL hd CHANNELS


You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.
