One of the most common causes of Emerson TV black screen is the failure of one of the transmission boards. The common name for the Emerson television screen suddenly displayed is the Black Screen of Death.
You should minimize the problem before trying to fix it.

Although various issues can affect your television, start with a direct sound test to go into complex solutions.
Here’s how to do an audio test on Emerson TV:

By using a flashlight test, you can narrow it down more. You’ll need to need to shine a light on the television.
Here’s how to do it:
- Get a flashlight and make sure it has maximum brightness.
- Stand about two to four inches from your TV screen and turn on the flashlight, shining it directly at the TV.
- If you see a picture on the screen with a flashlight on, it means there is a problem with the inverter or power board in the TV.
Step #3. Check Power and Connections
Most times, the best solution is an unlikely and straightforward one. Therefore, don’t panic.
Ensure that everything is in order and there is no loose power connection, then proceed to perform a factory reset on your Emerson TV:
Here’s how to do it:
- Unplug your TV from the power source after turning it off.
- Press the TV power button and hold for about 20 to 30 seconds.
- Release the TV power button and connect the TV to the power source.
- Switch it to a different device if you are trying to view an image from another device, such as a cable box. If this doesn’t work, access the settings menu on the television.

Here are the things you’ll need:
- Soft towel or cloth to protect and cushion the TV screen.
