Solution for "unwanted fire" during machine powering off

Postby Tech_Marco » Sun Dec 11, 2011 12:54 am

Following is a solution to solve the unwanted laser firing during powering off and having the "Laser" button press before powering off. Four components need to be removed from the main board.

1. Ground yourself to remove statics accumulated on your body in dry season.
2. Open the front cover of the silver box (main unit)
3. Locate R118, R174, D38,D39,D46,D47 (see pictures)
4. Remove all the components mentioned above with a soldering iron
5. Cover up and completed
