Case 3: Backlight Flashes then Turns Off

• Check on schematic: Inverter section – OVP (overvoltage protection) and lamp current sense resistors.
• Action: Locate the inverter IC (e.g., OZ964). Pin 2 = OVP; short to GND temporarily (test only). If backlight stays on, one CCFL is bad. The UPD schematic may show lower-value sense resistors to make protection less sensitive.
