SOURCE: sound on 2 channels a problem

I diconnected a recently acquired Panasonic DVR which was hooked up between my TV and the cable signal source, but this had no immediate effect on the two channels. I then reset the TV by unplugging it over night, and by changing the settings on the sound menu. These actions removed the problem. Is it possible that the DVR caused the problem?

SOURCE: Any idea why on my

If you do not have problems with picture and sound on all the other working channels, then the problem you are having with 57 & 58 cannot be a short. The problem you are having is that those channels will not tune in properly through your tuner and this is why you get intermittent sound when they are trying to tune in. The sound tunes in easier than the picture. You said that you have programmed the channels again and I am assuming you are talking about the autoprogramming mode. Try to program those channels individually by deleting them and then readding them. If you cannot do that then you need to take the tv back since it is new or have warranty service look at your tuner and setup your tuner by making adjustments to it directly. Good luck and God bless.

I don't have signal on my tv and there are no program's to watch as they are all blank. Is just a brand new tv I bought like 2 days ago


What make and model of TV do you have? What is your signal source (OTA (indoor or outdoor antenna), cable, satellite)? How is the TV connected to the source?

The model is important since some "TVs" are actually only monitors and do not have tuners. Then you need to connect to a set top box to watch anything.

Assuming the TV has an ATSC (digital) tuner for OTA, check that your antenna is pointed in the correct direction for the stations in your area. Use antennaweb.org or tvfool.com to identify the direction. Antennaweb assumes an external antenna and gives a very conservative list of stations. TVfool tells you the type of antenna needed to get any station (assuming no trees or tall buildings that might block the signal). Depending on your TV, you will need to enter the menu in order to correctly set the incoming signal type and scan for channels. Digital signals are either enough for the tuner to interpret or not available. If your signal is split between several TVs you may need an amplifier to get enough signal. Sometimes, the amplifier may fail and filter out all stations in certain frequencies. (Older TVs often only had a NTSC tuner; there are very few NTSC stations still broadcasting. They are low-power and thus you may not be able to watch them if they are far away.)

If you have cable without a box, which type of cable signal is coming in? Digital cable is QAM and not all TVs have a clearQAM tuner (that reads the unencrypted signal).

If you are using a set top box, make sure to set the TV to the correct input (HDMI, component video, composite video, coax and the correct number if there are multiple inputs). Make sure that the box is also on. If the set top box requires the TV to be set to a specific channel (3,4,60), make sure to go to that channel.

I hope this helps.

(For the US, the digital OTA tuner is ATSC and QAM for cable. In other countries, different signal formats are used.)

Do I have to subscribe to directv to get any high definition stations?


DirecTV provides the most HD content. But no, the correct off-air antenna may pull in local HD stations, depending where you live. Also, cable and DishNetwork provide HD channels.

How do i get hd channels with no cable ? just antenna


If your TV has a digital tuner, you can get any HD channels if you use the correct antenna pointed at the transmitter and are close enough to the transmitters. (Antennas labeled as HD are not always appropriate for your location.) Your TV will downgrade the signal to 480i if the TV can't support a 720p or 1080i resolution.

First where do you live? Use antennaweb.org or tvfool.com to determine the correct placement of your antenna for your area/stations. AntennaWeb uses a very conservative signal strength calculation despite assuming an external antenna. Tvfool will give the antenna color rating which is also provided on the antenna package. When properly installed (with no trees or hills blocking the signal), the matching antenna should receive the listed channel.

If you use a splitter to share the signal with several TVs, you may need an amplifier to bring the signal strength to that needed for the tuner to interpret the digital signal. (Note: amplifiers and splitters can fail and the amplifier may become a signal filter blocking the signal; test the antenna strength on a direct connection if there is a problem.)

If you do not have a digital tuner in the TV, you may have gotten an SD digital to analog converter. These are the more common (and available with the government coupon) converters. You will need to get an HD capable tuner to see the full HD signal.

Please add a comment with your TV model and antenna choice for additional support.

(antennaweb indicates that my external antenna should only get the stations 10 miles away. We actually receive the channels from 30 miles away. We use an amplifier splitter to feed the signal to several TVs. I set up two indoor antennas for a neighbor's TVs. One gets the signals from the transmitters 30 miles away and the other from the transmitter 10 miles away. Both get HD from the stations with HD broadcast (not all channels are in HD here). The difference is totally due to antenna placement.)

My toshiba 32DTIU has sound but no video


The "Toshiba 32DT1U" is a 32" class 720p 60Hz LCD TV.
Other than checking the connections, and making sure that you don't have a headphone port with a cable plugged into it,
I don't think there is much consumers can do with recent date manufactured LCD TVs, as far as repairs go.
Hopefully helpful,

My tv comes on and has "unusable signal" floating on it


What is your signal source, OTA or cable? Did lightning or another type of power surge recently hit? Make sure you have the TV on the desired input.

If OTA check your antenna direction and that you have the Channel Setup (from the menu) set to Antenna. Also check if you have the right antenna to get stations in your area. Antennaweb.org gives the most likely channels and directions. tvfool.com will give more detailed information and more stations. Both sites assume outdoor antennas but the direction information is always good. Look for new construction or big trees that might block the signal. Do you have multiple TVs sharing the same antenna? You might need an amplifier.

If cable, check the Channel setup. Check for someone recently damaging your cable installation (cutting the wires, trying to split the signal to get it for free) Splitting the signal to multiple TVs may also be an issue, get an amplifier of the correct type. Some cable systems may require a bidirectional amplifier.

If you recently had a power surge, see if the TV works with other inputs.
Tuners can be replaced if the TV is worth the labor costs for you.

I hope this helps.

( My household had three tvs and a digital to analog converter that lost their tuners after a nearby lightning strike. We chose to replace the TVs since two were over 15 years old and the third was also out of warranty.)

Lost several stations afyter conversion like al PBS stations. Is there something we can do?


Try rescanning for new channels. Some stations changed their Digital transmitter frequencies when they took their Analog transmitters off air. Rescanning will relocate those transmissions.

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.

btn_top_gold.gif spacer.gif line_gold.gif spacer.gif spacer.gif5. Why do I still see black bars on my widescreen TV when viewing certain widescreen DVDs and HDTV broadcasts?
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.
