If you are connected to a high definition cable box or satellite tv box you would not need to turn to channel 3 on your television. The television would need to be in the right input either component or hdmi. If someone connected the tv to the cable box or satellite tv box with a coax cable like an antenna cable then the tv channels will be available on channel 3 as well but they will not display in high definition. You change channels with the cable box/satellite tv box remote control. If the above is not correct and you are only connected to an antenna cable and not to a cable box or satellite tv box you will need to complete a channel search from the tv menu. It sounds like you are using a cable box/satellite tv box and that the tv is on the wrong input. If the cable box/satellite tv box is not working (i.e. just a black screen) on your television than that is a different matter entirely.

My vizio is blinking back and forth from the blue no signal screen to the actual hdmi input screen which is connected to a cable box. What is going on?

Have you tried a different HDMI input? (If available.) You may be able to test the cable box of PS4 using component cables to confirm that all but the HDMI is not working. You may try pushing or holding the HDMI cables to see if you can make the problem better or worse to identify a possible flakey HDMI socket.

Monitor goes black - green light stays on

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

I bought a new TV for my #2, but is says I'm not getting a signal when I hook it up to the cable. I have it on channel 60

djpeter770

You can go to TV 1 to make sure TV 2 is suppose to be set to channel 60. Did you run the auto setup on your TV? If you have already run the auto setup on your TV, unplug the receiver from the electrical outlet for 10 seconds and then plug it back in. This will make the receiver reboot and re-acquire satellite signal. Then see if you get a picture on your TV 2. If not, the last thing you can try is changing the channel from 60 to 73 through the receiver.

With your DISH remote at TV 1, press the Menu button - Main Menu will display on the TV 1. Then press 6 (System Setup), 1 (Installation), and 5 (Modulator Setup). On the Modulator Setup screen, move over to TV 2 Out and select Cable, then press select on the remote. This will automatically change the channel from 60 to 73. Highlight Done on the right and press select. Cancel out of each screen till you get back to the TV screen. Go to TV 2 and put the TV on channel 73. You should get a picture. I hope this helps.

Don't know what channel the dvd is suppose to be on. TV is set on 4 and I can't get dvd to change to four.

DVD players don't carry signals to channels. They carry signals to inputs. Check the back of your TV. If your cable coming from the DVD player goes into "video 1" set the tv to video 1, etc.

Can only change the channel to single numbered channels.

Three dash option does mean it will look for three numbers. You would then have to put in three digits, so for example if you want to go to channel 31 then key in the numbers 031, for channel 42 key in 042, If you want a lower such as channel 8, then key in 008. Try this.

No signal

You have changed the input to a selection that does not have a signal. Look at where the cable goes into the TV, this should show the name of that input, then change input back to that exact one via your remote.

Front Audio Video inputs not working

What model TV is it?
it may be you need to change the input to video 1 or video 2 to get those front jacks to work. if there is a TV/Video button on the front you should be set. If not you may need the remote control. Sometimes changing the channel to below channel 1 will give you that option.

TV input

it is likely that your tv is interpreting a random button on your remote as a signal sent for it to change inputs, next time this happens turn the tv off and back on and note what comes up on the screen, for example video 1,

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..
