Cannot watch channels past 13

For some strange reason, one morning the screen just went blue. We have a coax connected to the cable input, and now, after scanning for channels, it only finds channels up to 13, nothing past that, even if I go directly to channels above 13, the screen goes blue again, with no sound. Any ideas?? I tried connecting the cable to a different TV and it is fine (goes up to channel 107). Thanks! I'm going nuts here...

Re: cannot watch channels past 13

Your tuner settings must be set on broadcast instead of cable. Below channel 13, they use the same frequencies so it doesn't matter. Find the tuner settings page in the menus and change the cable/air setting.

Our screen turns blue and goes to new devices input. We have nothing else connected to tv except Brighthouse cable box. If we push the exit button on the tv remote it then goes to showing a cable box and...

Your TV probably has multiple "inputs" (coax, HDMI, component, et cetera). Use the "input" (or "source") button on your TV to cycle through all those available "input" streams.

If you select "coax", and there is *NO* coax cable connected to the back of the TV, you *WILL* see the "blue-screen". Select a different source that is "active".

Trying to set up my new elements tv with a uverse wireless box. Did a channel scan but still can't find any channels. Help please!!

Is this a high def tv? Are you using an hdmi cable, component cable(red green & blue) or a low def coax cable to connect the tv? If coax, the tv needs to be on channel 3 or 4. If hdmi or component cable is used you need to change your input on the tv with your remote to the matching input you wired it to. The uverse stb (set top box) changes the actual channels once you have selected the correct input.

I have a apex 32-inch tv model (AT3208S), This tv was connect to a converter box, the other day electric power went out in our area for about 8 mins or less, once the power was back on the tv screen was...

OK, I have one of these TVs, and here's a thought: There's nothing wrong with the TV nor with the cable converter box. Please bear with me. Since I don't know how much you may know about TVs in general and this one in particular, I'm going to assume you know nothing and go from there.

This TV has several different "inputs", which are ways a signal can be transferred from its source to the TV, where it "outputs" the video image. I believe this particular TV has 5 different inputs: In descending order of the quality of the video signal, there're one S-video input (a 4-pin video connector plus red & white audio), three composite video inputs (3 connectors each: yellow video and red/white audio--audio connectors are the same for both s-video and composite), and one coax connector (a single large screw-on connector with a little wire sticking up through the center of it) for a total of five different inputs.

The problem with these Apex TVs is that they always default to the Antenna/coax input first when they are restarted. Most people use the TV to display an input signal (like the cable box or a DVD player) connected either to the S-video or to one of the 3 composite video inputs, not to the coax input, which just displays the channel numbers from 1-125 when it's set to do that (hit the "display" button on your remote to toggle showing the channel numbers for the coax input). If there's no signal coming into the coax input, the screen with appear blue. (If it's blue, it simply means it's not getting a signal via the input to which the TV is currently set. You can turn off the blue screen in the menu settings, but then you'll just get a blank screen. It's probably better just to leave the screen blue; at least you can tell the TV's actually trying to display something that way.)

You have to manually select the proper input by pressing the "video" button either on the remote (lower right corner) or the "video" button directly on the TV (hidden control panel under the middle of the margin around the bottom of the TV screen. You'll have to press on the door, and the whole control panel rolls open to reveal another set of composite inputs and some buttons. The video button is the one farthest to the left.)

Anyhow, by pressing the video buttons, you'll cycle through the various inputs. Assuming your cable converter box is functioning properly, powered on, receiving a signal from the cable company, and connected to the TV via a(n) appropriate wire(s) connected correctly, you should see the output from the cable box on the screen when you cycle through to display the proper video input.

Another possibility: the power outage fried the input to which your cable box was connected on the back of the TV. If that's the case, your cable box would probably also have sustained damage. You can check to see if the various video inputs on the TV are working by connecting different source inputs (like a BluRay/DVD/VCR player, video game console, video camera, etc.) to one of the other inputs and see if you get a picture when the TV is set to the appropriate inputs. (Remember, the "video" button is what selects/changes/cycles through the various video inputs.) One of the sets of inputs went bad on my TV. I just use the other ones.

My 42 inch sylvania plasma tv does not have a coax connection, so how do i hook up my cable to the audio/video connection? i know there is an rf converter to transfer audio/video to coax but i really...

Since your TV only has audio and video input jacks, you can connect those to audio and video output jacks on the VCR. Now connect the coax cable to the RF/ant input on the VCR and you'll have to change channels by using the VCR channel selector.
Let me know if you require further assistance.

Philips flat tv. Can't get it to hook up to dish network. The room where the tv is there isn't a dish box. We have to watch what is on in the other room. It only has one coax cable to hook up. Don't know...

I should be channel 3 or 4. This assumes that this coax cable is coming out as a TV R.F. connection of a Dish Network Box (Satellite Receiver) intended for direct connection to an old fashioned NTSC (channels 2-13, 14-83, possibly even has cable channels depending on how old?) TV.

If this coax is the output of a coax going directly to the Satellite Dish or through what might might look to you like some kind of fancy splitter (called a Multi-Switch) the you WOULD NOT want to hook that to your old NTSC tv. The frequency is too high ... etc. etc... you would need Dish Box (as you call it) a.k.a. a Satellite receiver - with a good and active satellite card from your provider.

Nothig bu a blue screen shows when turned on

Blue screen of Death?
No, this is not windoze.

can you change channels?
a blue screen usually means that you don't have a signal.
Is it hooked up through dvd/vcr player?

Try a straight connection to cable or antenna.

If it remains, then it requires surgery.

HD cable question

It sounds like you dont have the right HD box. When connecting HD you will use an HDMI cable or a component cable consisting of 5 cable total 3 for video two for audio. Coax cable is not used to connect HD to your TV / Monitor.

Humm coming from speakers - can't get cable to work

The RF input is the correct one for a cable signal. The other sources use the RCA and other ports which you can connect to other devices, like DVD or VCR players.

If the humm noise only happens when you're on the TV channel then it's likely just the station. Try changing the channel and see if that helps, and make sure the coax is screwed in all the way. Also make sure the other end, if connected to a VCR or other stuff, is tightly attached. If you share cable with many other people and the signal has snow (white spots on the TV), then you may need to buy an RF signal amplifier to reduce the noise.

Source changes the input (RCA versus coaxial versus component inputs), change the channel for different channels..
