Hunter Genesis: LCD/Display Has Missing Lines/Black Squares
LESSON SUMMARY: This lesson is designed to assist the user in troubleshooting which component failures within the satellite could cause the LCD on the Timing Mechanism to display black squares or missing lines of text/data.
Special Tools Needed: None
⚠ CAUTION: THIS LESSON MAY INCLUDE INSTRUCTIONS TO TEST HAZARDOUS VOLTAGES (120V-240V) THAT CAN CAUSE SERIOUS INJURY OR DEATH. IT IS RECOMMENDED THAT A LICENSED ELECTRICIAN BE CONTRACTED TO PERFORM SUCH TESTS.
🛑 STOP: ALWAYS TURN OFF THE POWER TO THE SATELLITE BEFORE REMOVING OR INSTALLING COMPONENTS.
If the display on a Hunter Genesis Timing Mechanism has missing lines or black squares where text should be, the Timing Mechanism, Power Supply Board, or one or more TRIAC Boards could be damaged. Follow the guided steps below to determine which component(s) require replacement.
TRIAC Boards:
The TRIAC Boards are located in the satellite enclosure below the Power Supply Board. Each TRIAC Board runs up to 10 stations.
Start by powering off the satellite using the On/Off switch located on the front of the Power Supply Assembly.
Next, unplug the ribbon cable for the TRIAC Board located in the first position from the Power Supply Board. The TRIAC Board in the first position will be located directly below the Power Supply Board.
Power the satellite back on.
If the display on the Timing Mechanism appears to function properly, the TRIAC Boards will need to be individually tested.
If the Timing Mechanism continues to display missing lines of data or black squares, further troubleshooting is required.
Online instructions for testing TRIAC Boards can be found here.
Timing Mechanism:
The Timing Mechanism is located at the top of the satellite under the top lid enclosure.
Start by powering off the satellite using the On/Off switch located on the front of the Power Supply Assembly.
Next, unplug the ribbon cables on the Timing Mechanism from the Power Supply Board and Communication Board (if present).
Press the clip on the right side of the Timing Mechanism to release it from the satellite.
Remove the Timing Mechanism and take it to a known-working satellite location to test.
*Note: Prior to installing the Timing Mechanism at a known-working satellite location, be sure to power off the satellite at the known-working satellite location. Power to the satellite should always be off before installing or removing components.
If the Timing Mechanism continues to display missing lines of data or black squares when installed in a known-working satellite location, the Timing Mechanism is damaged and should be replaced.
If the display on the Timing Mechanism appears to function properly when installed in a known-working satellite location, the Power Supply Board at the original satellite location will need to be tested.
Replacement Timing Mechanisms can be purchased here.
Power Supply Board:
The Power Supply Board is located in the satellite enclosure below the Timing Mechanism and directly above the TRIAC Board in the first position.
Start by powering off the satellite using the On/Off switch located on the front of the Power Supply Assembly.
Next, unplug all cables and connectors from the Power Supply Board.
Proceed to unclip and remove the Power Supply Board from the satellite and install a known-working Power Supply Board in the satellite.
If the display on the Timing Mechanism appears to be functioning properly, the Power Supply Board that was removed from the satellite is damaged and should be replaced.
Replacement Power Supply Boards can be purchased here.
