Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

Turn Off the display. Unplug it from the power too if you can.

Leave it that way for at least 2 hours to cool off and rest-reset.

See if it works better after that.

How old is the display?

What maker, and model, is it ?

What transponders and/or GPS antennas, is it hooked up to? check all such connections. Re-seat every connection to it.

Check the voltage supplied to it, with a voltmeter. What do you find for DC Volts?
