I am trying to find out how to fix my LED Opti Tri PAR. Recently I have lost all the Blue LED's. Has anyone had this problem or know what part likely needs replaced?
Thanks

if you lost all of the blues then most likely the led driver (which is located on the main pcb) has gone out. go to parts.elationlighting.com then enter part# 7656001-020

Is there anyway to test this before ordering the part other than swapping it with one from a good light?
Measure the voltage on the 5 pin plug going to the LED out board.

Available at Digikey.com, or .ca, etc. since Elation is just board replacement.
Measure the voltage Plug next to it, it should be...
