On mine, it was dirty push-button switches.

On start no dot beem in screen, pushing the beem finder you can see the beem dot, when calibrating the probe if you keep holding the beem finder, you can see 2 parallel short lines of 1 square long. It look like the beem is out of the screen. Any help to continue troubleshooting. Thanks a lot. Regards.
