Control seems to be working but unit not responding.


Check your remote control by using a camera or cellphone camera as your eyes to confirm if the remote control is ok. Point the remote control transmitter to your camera and check if a light emits in your remote control transmitter. If no light then the remote control is defective, but if the light is present then the remote is ok and the unit receiver board itself is defective.

Check also if there is a reset or rst button on the remote control, press the button and test the remote.
