A Misbehaving Minolta Spotmeter M

[BradleyK]

Sitting around this afternoon, and doing nothing particularly constructive, I decided to do an inventory and quick cleaning of the equipment I was taking to the Island with me this weekend. Much to my surprise, I found my Minolta Spotmeter with its full display showing. I first thought, OMG, I had left the thing on after my last trip out. Upon closer examination, however, the "measure-lock" switch was left in forward (i.e. "lock" or off position). Removing the batteries (obviously) turns the thing off. Reinserting the batteries - with the "measure-lock" switch in the lock position - results in the illumination of the meter's full display. Any thoughts? Anything I should look at/check/tamper with before sending it in for repair?

I have personally opened my Spotmeter F (probably similar to yours) and closed it several times, making some soldering inside as well, without negative consequences.
