645Z Mode Dial fine (thought it had malfunctioned)

My 16 month old 645Z has a malfunction of the mode dial. When I place the dial in TV,SV or P,it stays on Aperture priority. I can use the dial and the camera switches to all the other modes appropriately. However, these 3 settings remain in A (aperture priority mode).I've updated software to 1.30. Reset to factory settings and reset all custom functions to no avail. The camera has been relatively lightly used for a camera of this quality. No proffesional use. Strictly amateur. Any ideas?

Of course, 5 months out of warranty period. Precision Camera, the Ricoh certified repair shop, charges 850 bucks just to look at it. I can use it perfectly well without those three exposure modes but Im afraid the dial will conk out completely at some point on a trip. Any ideas??

The fact that only these 3 modes are giving you trouble suggests that perhaps the aperture ring on the lens isn't set to "A" (you'd see the aperture value underlined in the viewfinder), or that communication with the lens isn't working (you'd see F-- in the viewfinder).
