How does a preamp die from sitting unused for a few months?

I’ve got an Inspire pre that I generally use with an Inspire amp.  I’ve been using the amp with a Cary pre but decided to put the Inspire in its place .

Installed, plugged in, turned on…and nada.  Tried different power cable, different outlet and still nothing.  Checked fuse and it’s fine.

Tried wriggling the PC and nothing.

I took the tubes out and will look into it later today but I find it weird that a piece of stereo equipment dies from sitting unused for a few months.  

Any idea what could have caused this?  Maybe a wire came loose?

Thanks.

relative humidity = corrosion.

environmental dust = poorly performing pots.

mouse and rat piss = corrosion an shorts.

rat chews on insulation = shorts

Didn’t read all post so if this was mentioned disregard. Did you check the wires coming off the IEC for cold solder joint. Follow that and see where it goes for bad connection.your definitely not getting power to the rails.I doubt it but handling it in winter static could have done something,

Count your blessing . I recently purchased a pre amp that was in storage . It aent DC voltage to my speakers . Literally had my speakers smoking and my speaker wire arched white when I pulled the wires . 

Use a Varaic to introduce voltage to the pre amp slowly.
