Simplified BACKLIGHTS Test 1. Activate Backlights – Disconnect Lead Cable from Main to Power Supply. 2. Measure BL Supply voltage at 1+ or at the supply diode cathode (stripe). 3. Remove Panel connector and measure again to compare. 4. If voltage is high and stays the same high reading a string of Panel LEDs are open. Replace the Panel. If the voltage is low and remains low the SMPS is defective.
