HP41C Display Problem

[Ignatz]

Thanks, all... squeezing was my first go-to... no joy, there, I'm afraid... Like I said, The calculator has simply sat on my desk since I've had it: the problem appeared one morning at switch-on. I'll try opening it to have a look.

I forgot to mention that it showed exactly this problem when I first received it, but I think that was due to its having been sat outside in my delivery space in freezing temperatures. As it warmed up, the LCDs came back to life... any chance the two things are connected?
