I had a Sony digital voice recorder that I wasn't using but was working fine. I pulled the batteries so they wouldn't corrode and threw it in my electronic junk box a couple of years ago. Today I was digging around and found it so I put some batteries in it and it was completely DOA, nothing on the LCD and no LEDs etc. even though it worked fine when I put it away. I took it apart to see if there was any corrosion or a broken wire, etc but nothing obvious that would explain its demise. So my question is what could have caused this? I know nobody can really say without digging in and seeing what failed but I was a little surprised that an electronic device could die just sitting in a box. Are there certain components that will die like this? Do you think it could have been avoided if I had kept live batteries in it? Thanks.
