Connect your multimeter to the LED output pins during power-up. If the voltage spikes up high (e.g., over 100V) and then slowly drops down toward the baseline 12V/24V rail, the 17IPS62 boost circuit is working correctly. The issue is an open circuit in the panel's LED strips (a burnt-out LED bulb has broken the loop), triggering the IC's over-voltage protection (OVP).
