Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

Hello, i just purchased a WL Arctic spyder 3 1.4 Watt from eBay. When i received it doesn't appear to work. The green lights on the smart switch come on and act as expected while putting in the "passcode" to activate. The problem is the laser never goes into the low power strobe function as expected. I have charged the batteries and it still does not work. I am hesitant to send it back since it is several weeks shipping. From my research so far it appears to be either a driver or diode issue. For reference the first time i pressed to tailcap button the laser momentarily flashed with out a passcode entered but never came on after this. seems bazaar. my questions are)

1) is this a drive or diode issue
2) is this DIY fixable
3) where can i buy the parts
4)what kind of cast and shipping times?

THANKS !!
