Check the back of your Apex TV and look for the video inputs. If video cables are connected, make sure they are fully inserted. If your cables look worn or damaged, replace them with thicker, high-quality cables. If you see image pixelation or frames dropping, you may have a weak cable signal.
Check the HDMI input number
Apex TVs are equipped with multiple HDMI inputs. Make sure your HDMI cable is plugged into the correct input on your Apex TV. Go to the “Input” button on the side of your TV and select the appropriate input.

Unplug the TV’s power cord from the wall outlet. Simultaneously press and hold the power and volume down (-) buttons on the TV (not the remote control) and plug the power cord in while holding the buttons.
Reconnect loose connections between the component device and your TV to determine if a loose cable is causing the signal loss. The easiest way is to locate the video input connectors on the back or side of the TV and trace the cables to the component device.
5.0 out of 5 stars good tv. The older reviews don’t do it justice. I’ve had this TV for a while now and have never had a problem with it and have used it extensively on my Xbox and PlayStations. Great little TV at a great price.
Replace the HDMI cable as it may have a short or other defect that is causing the black screen issue. Unplug the TV for 5 minutes to attempt a reset. Disconnecting the TV will reset the TV and fix any transient issues. Factory reset the TV to fix the problem.

It is more difficult to change settings without the remote control. There are several ways to accomplish this task, but this seems to be the easiest: Turn the TV off and then back on. Once the TV logo appears, press Channel and Menu buttons simultaneously.
