Question about Televison & Video

1 Answer

My tv keeps turning off and changing channels when I'm on HDMI input but no other channel does it do this. It turns off every 1-10 minutes that I'm on the HDMI input but it has also changed to the VGA input and to the channel 75(The channel I use for my cable box) oh and I may also add that these are the only three channels I ever use on my tv. And thanks for any help you may provide!

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.

Tv setup - cannot get past auto channel


Connect the TV to the Comcast box using an HDMI cable, then set input on the TV to HDMI - that's all. You then select channels on the Comcast box , not the TV (although the TV remote can be programmed to change channels on the cable box)>

How do i get the TV to play satellite? it just says weak signal when I turn the tv on. JVC RM-C18G


It has to be on the right channel. If you are supposed to be on channel 3, 61, 73, 113 (ask the satellite company which one you should be on) then you'll have to change the channel. If you are not supposed to be on a channel you have to find out which input you're supposed to be on (video 1, video 2, video 3, av 1, av 2, av 3, hdmi 1, hdmi 2, input 1, input 2, input 3 for example).

I have a brand new straight from box LG TV model 32LD320. I have unpluged the HDMI from old TV ( where was working 100% OK) plugged into new TV. Mains switch on - and cannot get any chanels to report on...


HDMI sends video from a source likea bluray player or 'cable box' to tv it will not send signal so you can program channels from it

turn tv to the HDMI input you plugged device into and watch cideo from that source

you will need to connect some type of antenna to be able to program channels on tv

very few tvs need channels programmed these days since most people hook up a cable or sattelite receiver and change channels that way

hope this helps if not give me more speecific details and i can help you more

good luck

No signal onthe screen


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.

I have a 19" phillips lcd tv and when i turn the tv on the phillips screen comes up but when it is going the show the channel it shut off by itself how can i fix this problem?


Hello. I may be able to assist you. If you are using a direct cable connection from the wall outlet;
  • Check the incoming cable or antenna signal connection to ensure that it is properly secured to the TV's antenna input.
  • If the connection is good, perform the automatic installation again to search for all available channels.
If you are using a coaxial connection from the Cable or Satellite box to the TV;
  • Set the TV to the channel specified by the service provider.
  • Change the channels at the Cable or Satellite box to view the program.
If you are using a video connection (CVBS, S-Video, YPbPr, HDMI) from the source (DVD, Cable or Satellite box) to the TV;
  • You do not need to perform automatic installation to search for the channels.
  • Press the 'SOURCE' 071218044349_22024.gif button on the remote control repeatedly to select the correct input source.
If you are using an HDMI connection from the source (DVD, Cable or Satellite box) to the TV;
  1. Reset the TV and source by unplugging it from the power outlet for 30 seconds.
  2. Turn on the TV and press the play button on your source device. If the source is HDMI CEC compliant, the TV will automatically switch to the HDMI input.
  3. If your source is not HDMI CEC compliant, turn on the TV and switch to the HDMI input.
  4. Turn on your source.
If you are sure you have selected the correct input or channel but still have no picture or sound;
  • Try resetting the TV by unplugging it from the power outlet for 30 seconds.
  • Press the 'SOURCE' 071218044349_22024.gif button to select the correct input source.
  • Check the connection cables.
  • Try the connected source with another TV.
  • Connect a different source on the same connection of your TV.

Sharp Aquos LC-37D64U Skips HDMI


The problem was caused by ME not setting up my Harmony Remote correctly after buying the new TV. The remote was programmed to turn on SA8300>turn on Receiver>Turn on TV>Select channel 3.

Simple change from select channel 3 to select Input 4.

HDMI input


This confused me when I first got this tv. The inputs (HDMI, CVI, etc.) are more like channels. Go to channel 2 and the keep flipping down the channels. You will see HDMI just below channel 2.
