Pulsar Display Power / Backlight Failure

Control panel LCD is blank or very dim, but generator may still run or crank.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blown display fuse, Loose ribbon cable to LCD, Failed LCD module, Low control voltage from PCB

Safety first: Turn OFF the generator and disconnect the battery before opening the control panel.

Check display fuse: Locate and test the small fuse feeding the display circuit; replace if blown.
Reseat LCD connector: Carefully unplug and replug the ribbon cable or connector between the main PCB and the LCD module.
Inspect for moisture: Dry any condensation inside the panel.

If the display remains blank, the LCD module or main control PCB may need replacement.
