Sadly my tbolt is sick as well. There is some fault that causes the processor to constantly reset. I already had the outer screws undone, so I popped open the case to look for the trimmer you need. There is indeed a solder blob on one side of the oscillator, under which I would presume is the adjustment screw. Hopefully a tweak there will take care of your error.
