Nanobox Duo: white LEDs always on even at 0%

[rsucre]

Hi.  I have an issue with my old Nanobox Duo.  Today, the white LEDs are staying on, even at 0%.  They dim, but do not completely turn off.  This happens only on the left puck.  Can you help me troubleshoot the problem?  Perhaps there is a short circuit somewhere in the left puck (solder points)?  My guess is that the issue is at the puck or lamp (and not the driver/controller box) since it is happening just to a single puck.

 

Your help is appreciated.

Thanks for your reply @Justind823

 

I unassembled the light and tinkered a little bit with it.  The problem went away after I unscrewed one of the screws that attaches the puck to the enclosure.  I put the screw back in place and everything is all right now.  Weird...  I guess there was some kind of short circuit or stray voltage due to salt creep or something, but nothing visible.

 

Any ideas?
