My TV picture went black. When I turned the TV off and then on again I received a message that read "no signal." Do I need a new TV tuner?

Black screen


Possible causes
  • Your TV is not receiving or displaying the signal from your DIRECTV® Receiver.
  • Your receiver has correct guide information, but is not processing video correctly.
  • You are viewing a channel where an upcoming sporting or special event is scheduled or has recently ended.

Solutions
  • Turn TV off and on.
  • Make sure light on front panel of receiver is lit.
  • Press the "TV/DSS" button on the remote control or front panel of the receiver (not all receivers have this option).
  • Reset the receiver by unplugging the power cord for 15 seconds.
  • Check all cable connections between the dish, receiver and TV.

If the picture is black, but the program title and description display in a banner the top of the screen:
  • If the problem is only occurring on a few channels, check the detailed description of the program through the on–screen guide on those channels. Often, we display a blank screen with a banner before and after a high–profile event to alert customers about the event.
  • Reset the receiver by turning off and unplugging the power cord for 15 seconds.
  • Run a signal meter test to check your signal strength (press "menu" and look under "setup" or "installation").

If your signal strength is below 70 (or below 60 on HD receivers) in clear weather on transponders 1 and 2, see our troubleshooting steps for "Searching for satellite signal. Please stand by." You may see zero strength on transponders 4, 12, 18, 20, 26 and 28. This is normal in many areas. Your system manual shows how to run cables and point your dish.

HOW DO I GET A CHANNEL ON MY TV AND GET THE MESSAGE "NO SIGNAL" OFF THE SCREEN?


If it shows "No Signal" it means it. It do not get any signal to display. Check all the settings. Refer its user manual for details. First, try to tune it to on-air program, by do an auto-tune function, after connecting it to an external antenna. Refer its user manual for more details. If it do receive all the channels transmitted, means, the set is OK, and the fault will be with the input selection, you've done. OK?

Second level tv has a signal but the main tv on first floor has no signal.


Hello! It sounds like there are a few things that could actually be going on. If you are getting no picture on the TV(you have a black, blue, or snowy screen), you will want to make sure that the TV is on the correct channel and/or input. You will want to be on channel 3 or 4, and possibly on a Video 1 or 2 or HDMI 1 or 2 input. If that doesn't work, then try unplugging the receiver from the power source for about 10 seconds. If you are still not getting a picture, let me know!

If you have a signal loss message on your screen (Signal has been lost, Partial SIgnal loss, COmplete signal loss, or Acquiring signal), you will first want to unplug the receiver from the power source for 10 seconds. You will get the Acquiring singla message as the receiver reboots after you plug it in, but that should only be about 5 minutes at the most. If you get the message after 5 minutes, you will want to make sure that all of the cables going from the back of the receiver to the wall are tight. If that still doesn't do it, please let me know!

WS-65807 picture goes black when using HiDef Signal


Tank, If the unit operates correctly on DVD then we can assume that the signal chain and display is operational. Can you substitute the Directv receiver to rule the box out as part of the problem? I know they came out and checked but how exhausting was the testing? Have you checked signal strength on the directv on screen setup? Low or marginal signal strength could cause intermittent blanking. When the screen goes dark does the audio continue? please let us know..
