I have a Samsung HCJ655W Projection TV. It has a built in digital tuner which upconverts everything to 1080i. I just recently upgraded my cable service to HDTV Digital. Here's my problem: If I go into the TV's video mode slection and choose HD Component, and choose a HD channel, I get a beautiful HD picture. Now, If I change the channel to a non-hdtv channel, I get sound but no picture. In order to get picture, I have to switch my TV to a standard cable feed mode, which gives a poor picture. Also, this requires using two remotes...one from the cable company, and one from the TV which is a real pain. From the standard cable feed, I can go to a HDTV channel and get analog sound and picture, but no HDTV signal unless I go into the TV's video mode selection and choose HD Component. The biggest problem is that I can't get the cable service TV Guide unless I am in HDTV video mode and watching a HDTV channel. Cable company has been out numerous times...no help.

Re: HDTV Cable box conflict
This set does not support 480I in the DTV mode, only 480P and 1080I is supported.
Try setting the analog setting in the cable box to 480p and that should take care of watching the set in DTV. Most cable boxes have a setting for format changes in the customer menu, depending on the type of box. If you are able to change the format, then the other inputs will not work since they need a 480I signal, as well as VCRs.
Another setup could be to use the S-Video cable or Video input jacks to get a better picture in 480I instead of using the cable input. However, when changing from HD to Analog, you will have to change to the correct input on the set as well.
Hope this helps.

You must have a digital tuner built in to the tv if you want to scan for Freeview digital channels. If you have digital cable or satellite the decoder box will unscramble the signal and send it to the tv through a scart connection or HDMI cable. Not all tv's have a digital tuner built in but if it is HDTV it can show an increased resolution image if the output from the cable box or dvd player is high definition.
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.
First Converter boxes are a poor economic investment. Second you have an HDTV. It does not need a Converter box. Just connect an amplified antenna.
Built-in ATSC QAM Tuners - QAM and ATSC tuners included to enable the set to receive Digital cable-in-the-clear signals, as well as digital terrestrial broadcasts. HDTV reception is possible by adding an Optional HDTV antenna
Using their online tool, select the Brand (Akai) and the Model from the list. If you cannot find your model in the list (which I was not able to for your television), they are saying that you most likely do not have a digital tuner.
All is not lost, however. As stated on the aforementioned site, you can consider one of the following options:
Purchase a digital-to-analog converter box that plugs into an existing television. The boxes, which are expected to cost between $40 - 70 will be available for purchase in 2008. Beginning in February 2008, U.S. households can request up to two coupons valued at $40 each. Each coupon can go toward the purchase of a single set-top converter box that will allow you to continue watching FREE "over-the-air" television on an analog set.
Subscribe to a cable, satellite or telecommunications service provider if all desired local broadcast stations are carried by that service.
Purchase a new television set with a built in digital tuner.
Listed on the page is further information that may help you to determine the status of your TV:
Consult your owner's manual. If that's not possible, you may be able to look up information about your TV set on the manufacturer's website. Or, you can take an up-close look at your TV set. You are trying to find out if your set has an input connection labeled "digital input" or "ATSC" (for Advanced Television Systems Committee, which is developing the DTV format).
If you bought your TV set before 1998, it probably doesn't have a digital tuner at all. Almost every TV set made before 1998 was a traditional "analog" set that can't display digital TV signals without either a special converter or a cable TV connection. If you bought a big-screen, projection TV between 1998 and 2004, it's possible there's a built-in digital tuner inside. But chances aren't great. Only a limited percentage of projection TV sets (and generally only those 42 inches in diameter or larger) included digital tuners before 2004.
If you've purchased a new TV set since 2004, your chances of having a built-in digital tuner improve dramatically. Starting in 2004, many of the TV sets sold at popular electronics stores have featured digital tuners that will let you receive the new digital over-the-air broadcasts starting in February 2009. But be wary: It's not a sure thing. Even some of the newer TV sets are purely display monitors that lack the internal circuitry needed to pick up digital broadcasts. Usually these sets have been advertised as "HD-ready" or "HDTV monitor" sets. That means they can display digital and high-definition signals, but they need help getting those signals in the first place. You'll still need a special converter or a cable TV connection.
this is correct! this tv does not have the ATSC tuner built in. 1080i is a format of the digital broadcast approved by the ATSC. you must have a source of this format to veiw this format. standard cable boxes and satilite boxes altho digital are not outputing HD formats so you need to have the HD boxes to veiw HD 1080i and the broadcasters must be broadcasting HD to get true HD.
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.
The TV you have was made prior to the DTV standard, so it will not have that capability built in.
However there are two easy fixes.
1) If you have cable such as Comcast, they will automatically start providing the Digital signal conversion inside the cable box for you so you will be fine. I believe the satellite providers will also be offering this feature.
2) If you watch TV from an antenna, then you can purchase a set-top converter for like $40 and request a coupon from the government that covers most if not all of that cost. You will want to check on the coupon first, because I believe you need that when you purchase the converter.
Either way, you should be able to watch DTV just fine without buying a new TV or other similar big expense.
I have the same problem here on this Samsung 40" LCD. its a 2007 model. everything was fine until recently. I had to reset my digital cable box. now the picture has the green tint. its ruined what was a nice tv, and it won't go away.
the hd sat box is your converter and is compatible to your tv (1080i only). if you are asking about local braodcast (over the air) this set doesn't have an ATSC (digital) tuner so you would need a box for that. but your sat company may be giving you your local broadcast in HD.
so if you are presently using an aeral antenna for your locals yes you will need the box.
if your locals are already being supplied by your sat company no the sat box is your converter.
note: some sat boxes have ATSC tuners built in so your antenna can be used by the sat box as well.
