Your TV has power and audio which is fine. Your TV T-con board is the component of the TV that gives you video/image and it could be defective. If its not your T-con board then it could be your panel aka screen is defective. Have a certified Tech come out and take a look at it.

SOURCE: Samsung HDMI issue

Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it.
However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input?
Or even an optical output from the TV to the receiver?

Televison station won't scan


If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

Why my dynex tv keep sayin no signal


Please follow the below troubleshooting steps and check the operation:

  2. Connect the input device to a different port on the TV.
  3. Make sure that you have selected proper input.
  4. Connect the device using a different cable.
  5. Auto Program the TV if you have connected cable directly to view TV programs.
  6. Auto Program the Cable Box using the Remote supplied with it if you're trying to view channels using a Cable Box.
  7. Unplug the TV for more than 1 minute and then connect it back and check the operation.
I hope one of the above troubleshooting step will definitely resolve the issue.

Thanks for using Fixya.

I cannot briing in a picture. Upper left corner of picture says it is on channel 4...upper right corner "no programs availab le"How do I program TV to bring in a picture.; I am on Insight Cable.


Typically the cable box is the source of your channel programming. If you're getting the "no programs available" you need to find if that notice is from your TV or your cable box. Check the connections from your cable source to the cable box and from the cable box to your TV.
Make sure that your TV is set on the proper source selection. Most Projection TV's have several (ant, cable A, B, DVD etc) check your on-screen menu for which one and make sure the cable is connected to the proper input ports on the back of your TV.
If you disconnect the cable between the tv and cable box and still get the "no programs "...then it's your TV.. but if you lose that warning, then it's coming from the cable box... If after checking your connections, disconnect the power to your cable box and let it sit for 5 minutes and then reinsert the power to the box and see if you get a reset with signal...... If nothing after all this, contact your cable provider to check their signal to your house and also the cable box.... Hope you have quick success on this!

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.

I have a jvc tv model av27530. Disconnected cable box b/c going


You probably have to find your original remote to the set and go through setup in your menu. On most sets, there will be a menu item which will allow you to switch from Cable mode to Air mode. If you have no Cable connected, then you must set tuner in Air mode.

If you are using an external device to run on channel three, then try this:
Make sure device (rather it's a vcr or game console), is hooked up to your Antenna Input connector. Also, some of these devices will have a small hidden switch on back that says 3 and 4. Move the switch to 3 position. Turn on device. Go into TV menu and do a Channel scan. This should auto program any device hooked up to the TV antenna input jack to channel three.

Keep in mind that you may not receive anything by Feburary of this year without an HD converter box to tune in channels with and outdoor antenna.

Initial set up w/directv


First, I hope you got an extended warranty with that. Otherwise it's a disposable T.V. after your warranty is up.NO PARTS are available. Hope it lasts more than a year..if your lucky. You need to change the channels on the direct tv box. Don't scan the t.v. You need the t.v. on channel 3 or video input that the box is connected to. Do you have hdmi cables? How did you hook the box to the T.V.? Did you read your book that came with the T.V. about hooking it up with a cable box??? Same thing as Direct T.V. box. That should show exactly how to connect. More info will help dtermind your problem.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

Why is there a long delay changing channels on my new Sanyo HDTV?


Are you connected to a cable box from your cable TV service Provider and use this device to select the channel you want to view? I have an HDTV which has the QAM tuning feature. Changing channels was instant until I accepted an offer from Cablevision for a 1 year rent free box and remote combo. The tuning box is a digital & analog Scientific Atlanta Explorer 4200 HD with a card slot for your subscription specs. This bypasses the tuner in your TV and the TV functions as a monitor.

If this is similar to what you have and you don't care about the channel/current program on screen display that appears for several seconds before the channel selection completes, perhaps the cable co. can adjust your box to supress this display if it will speed up the channel selection.

There is another annoying problem with this box. If you have a fraction of a second ac power interruption which might not even cause your computer to reboot, the cable box goes into a reinitialization that could take 5 minutes or longer. In my opinion, it is not worth the $6.50 per month charge we will receive when the year is up.
