Hello all,

First at all sorry for my english.

I have a Mako 46 with this issue:

I haven´t any error in display. I send to film any work, or internal test and the imagessetter always film in black.

I suspect about the board from laser, maybe not module.

Some tips? You know why happen this?

Thank you in advance for your help.
 
Hi strong recommend you:
Test the power supply in the Laser drive board.

Thank you very much Chock.

But, please, could you help me say me where is the Power supply laser board?

In the Optical Assy I have 2 boards, the board with 2 flat cable behind the optica, with several potentiometers (VR33)l and other small board on botton of optical. And also, The Power supply, Is the regulator 7905 and 7805? I have also 2 semiconductors in the botton of the optical. What of this parts I have to check?

Thank you in advance,
 
Thanks Chock.

Unfortunally I haven´t schematic from this machine...You have? If you have, could you send me by e-mail?

Thank again!
