Tv wont tne in to ch9 why iam getting all the other channels


If you are using an antenna to receive broadcast TV you may have to rescan to add channel 9 back into the TV's channel list. If this does not work, it may be seasonal or a weak signal from your channel 9 broadcaster. I use a signal booster on my antenna (purchased at Radio Shack..)

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.)

My panasonic viera has just stopped working. I can play a dvd but not watch tv, It says no signal. I have checked all leads and none are loose. It worked yesterday!! What is wrong with it? Please help


What is your TV source? Is it OTA, cable or satellite? Do you use a set top box or a direct coax cable connection? If you have OTA, what antenna do you use?

Try the following depending on your setup:

For all, check if a lightning/surge protector has taken a surge and needs to be replaced. These are placed in the coaxial line to divert a surge that could destroy your electronics. Also try replacing the cables. Check exposed cable for damage.

For OTA, first check that your antenna is oriented to point to the transmitters in your area. (Outside antennas will sometimes turn in the wind; indoor ones can be bumped.) Try a new coaxial cable. If the antenna has an amplifier (or you use a splitter with or without an amplifier), try connecting the cable directly without the device. I've had several amplifiers fail and turn into signal filters (blocking all of the signal).

For any system with a set top box, make sure that the box is on. For satellite, make sure that your dish hasn't moved out of alignment.

To check if it is the Viera TV tuner or the incoming signal, try another TV at the same connection. If you have cable and another TV gets no signal directly connected to your incoming connection, you may need the company to fix the incoming cable. (Underground cables can be damaged by rodents or neighbors who dig without checking for utilities.)

I hope this helps.

Cannot get it to change the channel to recieve cable from the cable box. it says it is on channel 2.1


If you are using the channel up and down buttons, sometimes it will skip channels. Try manually putting in 03 using the remote to change to channel 3. Also make sure that in the TV menu you have the TV set to Cable instead of Antenna.

Hello, I am currently having a problem with my Audiosonic KM0767 Standard Definition Set Top Box. When we first bought it we wired up all the plugs and it worked great. We then moved onto Foxtel...


did you switch the TV's incoming signal to digital antenna? For the cable box it was probably set to cable antenna or analog inputs, not all TV's have automatic switching for antenna feeds. My Mitsubishi has 1 digital and 1 analog antenna input and the cable box will only work through the antenna input if it's the analog antenna input and it's tuned to channel 3 or 4, -(or through a seprate HDMI, PROSCAN, SVCR,or a yellow RCA plug input)- and when the analog antenna input is selected the TV will tune all analog cable channels that the cable service offers if a box is not used. likewise the TV will not tune any channels at all if it's set to digital antenna inputs. It will tune all local channels only when set to digital antenna inputs.

Attenna hook up


Yes, This set does not have a digital tuner built in. All over the air signals are now digital. This set will work without a converter if hooked up to standard cable,DVD,VCR or Video game console. If you purchase a DVD with a digital tuner built in you can skip the converter box and hook your HDTV antenna directly to it.

"Failed to receive broadcast"


On your TV remote,press "INPUT".It is hard to find,but it should be there.Select"TV" and press"ENTER" button.I believe it is on the top of the list.On some cable boxes you have to select channel 3 and use the cable box remote to change channels.Also,make sure your TV antenna setting is set to "Cable" from the "Air/Cable"(Antenna setting).You will have to read your manual to find out how to get to this menu.After that do a "Ch Search"[Channel search].This automatically searches for all available channels and stores them. It will take some time.You will see the channel numbers as it does it's search.This is done so when you press channel up and down keys it will only go to next channel available and not to one with no signal.Hope this is of some help.

Everything on the TV works EXCEPT live TV.


Please clarify a few things. Are you using cable TV, satellite TV or a TV antenna? If cable, are you using a set top box (and is it powered on) or does the TV convert the cable info. If satellite, is the set top box powered on? If off the air (antenna TV), can the TV receive the new digital signals and if not, do you have a digital converter box between the antenna and the TV?
