Reply to DJM-800 Color Effects Light

The color effects light for my filter and my harmonic effects has stopped working but the effects work just fine. The only reason why this has become a problem is because I can't really be sure if the effect is on or not.

Has anyone ever had this problem before and found a solution? I have a local shop which I'm going to get a quote for the repair, but do you believe it's something that can be fixed at home? I do have experience fixing electronics, the USB socket on my LPD8 came off its port and i got it working again.

Any help is appreciated.
