My friend... now you let me down !!!

I was just looking for minolta service online when I found your note about your experience...
It happened to me two days ago... I still have the hope it could be because I use the wrong batteries... I`m going to buy the rigth ones today and try.
I have my camera for two years... and it never happened before, till I use the wrong batteries

- Do you think could be it?
How much did you pay for the service? including shipping...
