Can't get cable channels, only goes up to ch. 13

I received this tv from a friend who was moving. Trying to hook it up and get cable working. When the coaxial cable is plugged in, I get channels up to 13 (otherwise nothing but static), but I can't get any of the higher channels. What do I do?

First check and see if you are on Cable or Ant. It sounds like you are on ant. Change it to cable. If you are on cable then it's you tuner, you need to replace it.

How do i get my Panasonic ct1388yd to register it's picture and its sound of my game console


The modulator is outputting channel 3 or 4 analog not digital. Channel 3 digital is not channel 3 analog. You have the opposite problem of those trying to receive TV on an older Analog TV. You need to rescan your channels to add the analog input. Assuming you TV still scan for those like mine does.

P.S. - BNC!!! Really?? I only see those on security systems these days.

I have a Channel Master amplifier model 3042 to increase the antenna strength on my TV and don't know how to connect it uh it's a Channel Master model 3042


Coaxial cable from Antenna to input on amplifier. Coaxial Cable from output of amplifier to Television, VCR or AV Receiver depending on what you have hooked up.

My cable box is hooked up but no signal can u tell me whats wrong


If you hookup your TV directly to the coaxial cable, bypassing the cable-box, do you get a few channels? If so, then the coaxial cable is carrying a signal, which is good.

How are you hooking the output from the cable-box to the input(s) on the TV? Coaxial output port on box to coaxial input port on TV?
Red/blue/green "component" outputs on box to matching inputs on TV? Red/White audio outputs on box to red/white inputs on TV? HMDI output from box to HDMI input on TV?

You have to "tell" the TV which of the inputs:
* coaxial (with TV set to Channel 3 or 4)
* component
* HDMI
to "listen" to.

Have new E370VL hooked up to Dish Network via coax. The picture jumps/blips? Connections are tight. Help.


This can happen when there is radio interference near the coaxial cables. Sometimes the interference is behind walls. The solution is to try a different combination of modulation and channel than what the DISH receiver is current set.

The DISH menu screen for this setting is Menu-6-1-5. With dual-tuner receivers, typically "TV 1 Out" is the TV that is connected in the same room as the receiver is located. "TV 2 Out" is the tuner that is fed to the remote TV via backfed coaxial signal.

All that needs to be done is to change the channel and mode going to the effected TV to something different. If your channel/mode is currently set to Air/60, try changing it to Cable/73. When you change the mode/channel in the DISH receiver, you need to set the remote TV to the same mode and channel.

Keep in mind that with some TV companies like VIZIO, they call their "Air" mode "Antenna". With VIZIO's the TV must be set on TV input and then go into the Menu to the Settings, Tuner Settings. Change mode type to match what you are trying on the DISH receiver, exit the VIZIO menu and manually enter the channel number.

Eventually with trial and error, you will find a mode/channel combination that isn't effected by your particular environmental interference.

Connected the coaxial cable to the tv but got no channels. the tv turns on but all I have is snow


Some possible things to check:

1. Are you trying to receive off-the-air broadcasting? If so, you'll need a digital converter box. This set doesn't have a digital tuner, so there won't be any channels for it to receive without the converter.

2. Are you connecting a cable from a cable converter box, satellite receiver or FiOS set-top box? Your TV will need to be set to channel 3 or 4 to see the signal from the device.

3. Make sure the center wire in the plug on the end of the cable isn't bent over, and that it extends far enough (about 1/8 to 1/4-inch) to make a good connection.

4. Do you know for sure that the cable you are connecting is working? Is there actually a signal on the cable? It may be disconnected somewhere else (at a splitter, for instance) or there may not be any signal source.

5. Have you tried another TV to test the cable? If the cable works with another set, the tuner or antenna connector on the snowy set may be bad. If the cable connector is tightened too much when hooking it to the TV, the connector may be damaged and this can cause the snow.

Start by checking with a known good TV. If that one is snowy, you can check the other possibilities. If it works, you'll know the problem is in your set and can decide what to do (repair or replace).

Hope this helps! Thanks for using Fixya.

Sharp digital tv cannot receive digital signal


This television would benefit from an hdtv indoor outdoor amplified antenna not obstructed by trees, aluminum, bricks, and etc. Make sure the signal type is air and not cable and complete a channel scan during primetime tv hours after connecting to this antenna. Buy a large one that you can mount to the wall usually in a large flat box on the shelf in the store. Philips has one sold at Walmart.

I am trying to hook up my Philips 19PR19 (made in 1998) tv to the dish network receiver, it has 3 prongs diff. colors attached and the cable cord is already to go in the wall...I don't see anywhere on the...


Because your TV is an older one, it might not have, what they call RCA inputs (the 3 colored cable) Red-audio right, White-audio left, Yellow-video. If I understand you.

You do have the option of using the 75-ohm coaxial cable inputs. Signal comes in from outside to the 722k, Output of the 722k to the 75ohm coax input on the back of the TV. Tune your TV to ch. 3 or 4. Make sure the switch on the back of the 722k is set to the same.

If you really want to use the RCA colored cables, then you need to buy an RF modulator, which integrates older tv's to newer products. But usually dvd players, not necessarily cable boxes, but it would work if hooked up correctly.

You plug the RCA red, white and yellow from the 722k, into the rf modulator, choose channel 3 or 4 on the modulator

Connect 75ohm coax cable from rf modulator to TV 75ohm coax cable input. Choose channel 3 or 4 on the TV.

Hope this helps.

How do we make my TV capable of receiving regular local channels without cable or satellite hook-up?


You would have to hook up an external TV antenna on the UHF/VHF band and run a coaxial cable from the antenna to the TV and plug in the "Belling-Lee" connector into the "Antenna" socket at rear of unit.. This should enable reception via "Normal TV"

I can't hook up the vcr


I would strongly suggest connecting a plain, coaxial cable wire from your sat box to the the ANT IN of the VCR. then use another coaxial to run from the ANT OUT of the VCR to the TV. Then you can change your TV to channel 3 or 4 as appropriate.

If you have a newer digital satellite receiver, this setup may not work. In that case, use two sets of red/white/yellow cables - 1 set will run from the out of the satellite receiver to the audio, video IN of the VCR. The second set will run from the audio and video OUT of the VCR to your TV. Then change your television to Aux 1, aux2 or whatever channel that corresponds to the red/white yellow.

Have fun!
