Problem with Redsail X700.

Hello,
My machine Redsail X700 a month. After 2 hours of use I have not had laser pulse by pressing the "test" button "PAD03" only 3 more low from the red test button "PSU". I changed the "MPC6515" card, the box "PSU" and the laser tube, nothing works ...
You have an idea or it may come from?
Thank you in advance.

Daniel.
