Why does my HISENSE 43E7KQ television turn on but display a black screen?

Question

Accepted Answer

If your HISENSE 43E7KQ television turns on but displays a black screen, several causes may be behind this issue. Here are the steps to follow to try to resolve it:

1. Check the connections

Make sure all cables, including the power cable and HDMI or AV cables, are properly connected and in good condition.
Try unplugging and then replugging the cables to ensure a good connection.

2. Change the input source

Use the remote control to select another source (HDMI1, HDMI2, AV, etc.).
It is possible that the selected source is not transmitting a signal, which causes a black screen.

3. Restart the television

Completely turn off the television.
Unplug it from the electrical outlet for at least one minute.
Plug it back in and turn it on to see if the display returns.

4. Check the display settings

Ensure that the brightness and contrast are not set to minimum.
A setting that is too low may give the impression of a black screen.

5. Test with another device

Unplug any external devices (set-top box, console, DVD player) connected to the television.
Turn on the television alone to check if it displays a menu or home screen.

6. Update the television software

If possible, check in the settings if a firmware update is available.
An update may fix bugs related to the display.

If after these checks the screen remains black, it may be a hardware issue requiring specialized technical assistance.
