Well guys, I pulled the screens and cleaned them but to no avail. They actually looked spotless but it was worth a try. Since I have very little tech info on this and the fact that this system is new to me, I have contacted the Komatsu dealer here to have them come out and take a look. The last thing I'm going to do, after checking the pricing and availability of the parts, is start throwing parts at this attempting to correct the problem. At the moment I am suspicious of the KVGT servo sensor, but I have no parameters to check it. Sometimes you just have to make that call to the dealer and let them figure it out based on their own experiences and familiarity. Hopefully, I get someone that knows the system well and not some trainee.
