[HELP FOR REPAIR] 1W 532nm DPSS CNI/LC

[ams09]

Hi all,

I need some help and/or some information to try repair this unit.
In the first time i want to work on head, i have others calibrated drivers for LD and TECs, the LD is dead, the ND:YVO4 looks like "burned"
Some pics:
Driver


Head (Collimation, KTP and OC removed )


ND:YVO4




I've found here a partial description about the trimmer fonction of one similar driver, but not the same ( i have the pics, but i can't found the thread... )

Thanks by advance for your feedback.

Regards, Christophe.

Thanks Chris...Yes it's the good link.

In mine i have not the "0 Bias" trim. In the same place i have one LM336Z2.5V labelled U8 (and only one fan on the right )
For the ND:YVO4 i don't know... it's dead you think...? I'm going to change the LD first.
If you want look more pics of this unit, just look my thread on the French section of Laserfreak, here: http://www.laserfreak.net/forum/view...?f=109&t=52101

Thanks by advance.
Christophe.
