Test 1:
So, firstly you can attempt to get the tv’s menu pulled up using the remote control or the MENU button on the TV itself. If the tv’s menu appears, then the issue is coming from one of your sources or components.
What would be your first solution after doing this test? Usually this would mean that either a cable box, sat box, coax cable, HDMI cable, etc may not be working properly, something is loose, or needs reset.
Reset ALL your TV’s components by unplugging them for at least 5 minutes, including the TV itself.
Make sure all your COAX CABLES and HDMI CABLES are tight and properly connected.
If you are able to, pull up your tv menu when you have the blank screen, update your TV’s firmware to be sure your TV is up to date and rule this out as the problem.
Just something to remember is that if the TV now works and there is no blank screen, the issue was either a loose cable, old TV firmware, or a component that needed to be reset and the issue is now resolved.
Test 2:
Is the component you are using TURNED ON and the TV INPUT is set correctly?
Sometimes it is easy to make a simple mistake and then to think your TV is broken. By just following these few steps, you can find a solution to this problem.
Be sure you have the TV INPUT set correctly and it is set to the component you are currently using.
Switch to all the TV INPUTS one at a time to make sure you have the component connected to the correct input.
Sometimes inputs are labelled incorrectly and this can cause confusion. If after turning ON the component and changing the TV INPUT, your blank screen is gone and the TV works, the issue is now resolved.
Test 3:
After you have reset your TV and made sure the components are connected properly, and you still get a blank screen, you may have a bad COAX CABLE or HDMI CABLE.
So, what is the perfect solution to this? You can try using different or new cables for the component you want to use.
Use a new COAX CABLE for SAT BOX and CABLE BOX.
Use a new HDMI CABLE for ROKU, AMAZON, DVD, BLU-RAY, X-BOX, PlayStation, etc.
Make sure there is no damage where the cables connect into.
If after using a new cable and your blank screen is now gone and you can see the picture and sound, the problem is resolved and the issue was a faulty cable.
