Jockstraps I have seen alot of the GR-d30,70 and 90's, here lately with that same problem, the fix falls between the dew sensor and the pre mda pcb that is mounted on the back of the mechanism assy. I have been just replacing the loading motor brackett assy and the pre-mda pcb to cure the problem for my customers that are under warranty. Let me know if you need any parts or any further help. Rex
