1. Do I need any additional equipment to watch HDTV broadcasts on my HDTV-compatible TV?
In order to view over-the-air (OTA) HDTV broadcasts, you need to be within the reception area of a TV station broadcasting HDTV signals. Some TVs may require a set-top HDTV tuner and an external antenna to receive the broadcasts. Your cable or satellite provider may also offer HDTV channels as a part of their service, eliminating the need for a separate tuner. Please contact your local service provider to find out what kind of HDTV services they may offer.

2. What is CableCARD and how does it work?
HDTVs with CableCARD slots can accept a small card from your cable provider that allows you to receive standard definition and high definition digital broadcasts without a bulky set-top cable box. Please call your cable company to find out if they offer this service in your area.

HDMI, which stands for "High-Definition Multimedia Interface", is the consumer electronic industry's first connection capable of transmitting uncompressed digital audio/video signals. Components featuring HDMI can transmit both digital audio and video over one convenient cable, replacing the tangled mess that resides behind many home theater components. HDMI also offers improved quality over traditional analog connections thanks to all-digital transmission. Digital sources like DVDs and HDTV programming can now be transferred digitally from source to display without analog conversions that can degrade the original signal.

Unlike the HDMI interface, DVI only handles digital video. Through the use of an adapter, a DVI device can be connected to an HDMI device, but only video content can be transmitted. The audio signal would have to be transmitted through other methods such as analog RCA outputs or an optical digital output.

4. What's the difference between 720p and 1080i HDTV broadcasts? Does my CRT projection HDTV support both?
HDTV signals can be broadcast in either 720p and 1080i. It's up to the broadcaster which signal format to use, and both have their benefits. Our CRT projection HDTVs display 1080i signals in their native format. For 720p broadcasts, you can use the settings on your HDTV set-top tuner, cable box, or satellite tuner to convert a 720p signal into a 1080i signal that your TV can display.

Your widescreen TV has an aspect ratio of 16:9 (1.78:1), which is the aspect ratio of HDTV. However, movies are filmed at several different aspect ratios, including 2.35:1. Also referred to as "scope", 2.35:1 is a very panoramic aspect ratio that provides a wide field of view in the theater. Scope is much wider than your widescreen TV, so it still requires the use of letterboxing ("black bars") to fit the entire image on screen. Some TVs and DVD players have a zoom function that allows you to blow up the image so it fills the screen, but the sides of the image must be cropped in order to do so.

6. What will 4:3 broadcasts and DVDs look like on a widescreen TV?
There are multiple settings for adjusting the appearance of 4:3 material on Panasonic widescreen TVs. It can be viewed with black bars on the sides, preserving the way it was originally intended to be viewed. Some viewers find the black bars distracting, so they might prefer one of the stretch modes that lets you fill the entire TV screen with the image. One such mode is the JUST (justify) mode, which stretches only the outer portion of the picture while leaving the center untouched.

SOURCE: digital tv tuner not displaying picture

. Try putting you tv set to channel 3 or 4. Try your tv in all modes. Check the back also to see if in the right spots with the wires. Check your channel scan status, try it on anntena and try it on cable, run channel scan on both. good luck. Try vcr wires if cable wires dont work. vcr wires are yellow red and white. Try another cable cord sometimes they get old. Try looking at your remote and setting it to tv.

How do ihook up a digital antenna to my tv


Dominic, you do not state whether you want large outdoor antenna or simple indoor.
If you bought your HDTV anytime during the past 8 years or so, it should have a built-in tuner for receiving digital over-the-air broadcasts. If you have an older "HDTV-ready" TV that only receives analog signals, you'll need to connect it to a separate HDTV tuner.

Trying to hook up a digital antenna but no channels coming in


You need to get a connection from a local cable or wireless service with a set top box to be connected to the input. Please check with your local operator and see if the set top box is needed for the digital feed.
Otherwise you might need a dish with the LNB to be used to the TV. Digital tuner means that the tuner is working to scan and memorising the full band width of the channels with digital processing and thus faster and crisp.
Check the details of the TV from a forum:

Make sure you have a good connection from antenna to TV. Check antenna and cable and cable connection to TV. Select DIGITAL button on TV remote when wanting HD channels. Remember HD channels are always digital. Also, any given TV station may not be broadcasting in HD at a given time. They can broadcast in digital but in standard definition sometimes. Your TV has a built-in DVB-T tuner. Try executing a channel scan to pick up all available channels. On-screen menus go to Digital Setup, then Digital Tuning, you can auto-tune or manual tune channels. The TV should take a few min. to scan thru available channels and store the channels its finds. Check with anyone in your area to see if they get HD channels (it is possible to be outside of the range of some TV stations) Your TV is a 2006 model and should still be compatible with local digital TV broadcasts but keep in mind digital signals could change in the near future (DVB-T2) and you may need a tuner/converter box to make the TV compatible.

Can I use a regular antenna


Yes. You can use a regular antenna for any flat panel HD TV. You're only limitation the type of antenna and whether or not your flat panel TV has a built in digital tuner. If it does, you'll be able to scan for digital channels without any additional components, including the High Def ones,  though you may not get every channel available with a set of rabbit ears. A roof top antenna will give you a stronger signal and more channels. If your TV does NOT have a built in digital tuner, you'll have to purchase a digital converter box and attach your antenna to it to receive the digital and HD channels. Good luck.

Digital built in turner


You'll need a better antenna. All the TV can do is show you the signal strength at the antenna input. If it's too low, only changing the antenna can help. This could mean simply adjusting the antenna position. You might need to replace the antenna with something larger or with a built-in amplifier. In severe cases, you might need to install an outdoor antenna to get a useable signal. With digital broadcasting it's all-or-nothing. A weak signal will either go undetected by the tuner or cause a blocky freezing (pixellated) display.

52G786 ATSC Tuner no longer works


I have the same exact model tv...Love it...ATSC tuners is in definition an Analog tuner. As the broadcasting companies change over to Digital broadcasting before the deadline in Febuary 2009 more and more local or Non-Digital chanels are becoming obsolete. You would have to purchase a converter box for your tv if your not planning on getting cable. Another way to gois if you have an old cable line running through you house (no incomming cable) plug you tv into that jack. That also acts as a antenna. The sweet part of all this is that your tv do have a QAM tuner or Digital tuner built in just need that digital antenna to pair it up.
