My unit shows nothing on the screen and the LED is a red continuous blinking light. What could be the problem?
Your installation itself may be causing the problem. Typical causes are overheating and sporadic line voltage drops. Check that the unit is properly ventilated. Consider having an electrician check the voltage, including the voltage with all a/v components, HVAC and other power-consuming devices turned on. If the problem persists an authorized technician may be required to service the unit.
