Hello StanPenn1 - I have the same issue with my L6 Shuriken 250 scale modeling guitar. Sounds like the same exact problem, Have you found the root of the trouble yet ? I have had my board out under a scope and extracted as much schematic info as I could. My problem is associated with the Main relay (NEC EA2-5NU) that is when it clicks or engages the white led is lit and guitar functions. The problem is that this does not always happen at initial power up and I find I have to cycle the power afew times to get it to respond. It has always finally worked, sometimes with 1 or 2 attempts or many more it's not predictable. I also have the variety of lights at the modeling switches and have not found any reference or pattern in there appearance. I have found the early schematic for the Variax pcb mk1 but not much of it translates over to the latest version, but there are many good points of reference. I don't believe I have a bad relay I think it is in some circuit that drives the relay that is in question. Any thoughts that might be helpful would be appreciated. The problem still exists but I seem to cycle my way around it eventually. I run/power through a Helix rack and love the system when it works. Would love to get my hands on the main board schematic if anyone has access to it. Pictures attached is front and back of mainboard, backlit to show via pathways. Cheers, Jack K.
