TS-930S – no display and on the bench

I’ve got no frequency display on my TS-930S! I’ve had this problem since I arrived in Kansas (note to self: I need to pack in rig myself next move). From what I can tell, the display is probably not broken but the PLL needs to be adjusted. The problem – how do I adjust the PLL? I’ve been unable to find the service manual and I’m hoping I can find someone who has the knowledge of how to do this. I’ve popped the top, but I’m not seeing anything that looks like I should be adjusting. While I don’t need this rig to operate (I have my Icom IC-7000), I really like this this Kenwood rig. It has a wonderful sound and great sensitivity. I hope I can bring it back to life.
