Reply to problem with Cue Led (pre listen)

Hello,

I own a VCI 100 I ordered at DJTechtools one year and half ago. I live in france and I use it every week on a club so sending it back to DJTT is not an option.

I have a problem with the led of the left cue (pre listen). the contact works and sends midi info but the led doesn't ligth when activated (despite the fact it's activated on traktor)
I supposed that the led is dead... Is it possible ?
Is it something difficult to replace ?
