@donkjr Hoping you can help me out. From all the posts I have read, you seem to be the most knowledgable so if anyone can do it, it would be you.
Here is my issue… the laser will not fire using the pulse key on the digital panel. I checked the Laser Power Supply (LPS) and found the following. With all connectors plugged in the “P” led on the LPS is lit. Pressing the test button on the LPS makes the “L” led comes on but the red “Laser” led does not come on and no laser is emitted from the tube.
I unplugged the control board connector from the LPS, obviously, the “P” led went off. Pressing the test button on the LPS makes both the “P” and the “L” leds come on, the red “Laser” led comes on, and the laser is emitted from the tube.
My initial thought is the water protection (WP) sensor is bad. I traced the wires from the WP sensor to the board to be sure they were labeled on the control board properly. They are. I disconnected the WP sensor connection and jumped a wire from the WP port to the ground on the control panel. I plugged the control board connector back into the LPS and tested the test button on the LPS. No change was noted. I checked the pulse button on the control panel and no change there either.
My LPS is MYJG-60W. Here is a link to one just like it.
Any help would be greatly appreciated. I am not sure where to go from here.
