S2 IS No power?

The unit is approx 36 months old, minimal usage, approx. 750 shots. It failed in the middle of use and had that electronic "burning" scent. The unit failed with the lens open and expanded to full zoom and when it shut down, it did not retract. I've tried replacing with fresh batteries, recharged existing ones, cleaned battery contacts with eraser, compressed air in battery compartment, but the unit just does not power up at all or makes any effort to fire up.

Any suggestions is greatly appreciated.

Thanks...

If you smelled smoke, chances for home repair are slim to none. It may have blown a capacitor or something. Had you been using flash, perhaps?

thanks, at the time of the failure, I was not using flash.
