Mono sound - in one ear

My Problem

The headphone jack was obviously defect. At the same time I decided to replace the battery as it was loosing charge to fast.

My Fix

It went quite OK. The trickiest was to get the switch at the right position and to get it to stay there. I had to open it again to correct the switch. Now all is OK!

My Advice

Check the switch operation and positioning. And be shure to have the correct screwdriver!
