Sensor3 LEDs flickering rapidly. Power appears to be flickering


The LEDs on the CEM3 are flickering rapidly and the CEM3 is not booting. LCD backlight may also be flickering. CEM3 does not boot

Description/Explanation of Issue

The large capacitor with the yellow hat (C31) may have been knocked hard enough during installation to damage one of its two solder barrels. As a result, power is not stable going into the switching circuitry and causing the CEM3 to rapidly and partially power on to cause the LEDs to flicker rapidly
