Have a Laserjet 4200L that isn`t LCD display.

The only other thing I can think of is the Dispaly Panel change, but I wanted to see if anyone has experienced this problem first.

That running cold reset.

Thanks

Have you checked the cable connection at the control panel?

When you first turn on the printer do you hear the fan run briefly? If no fan is heard then you might have a power supply fault.

When you turn on the printer do you feel the power switch toggle? If not then check the rod connecting to the power switch.

hope this helps
