Elektronika MK-52: The MK-61 big brother?

[Daniel.]

Hi there, I'm new here and I live in France.

I just received this calculator that I bought as NOS but won't light up.
I've removed the condensers and checked the VFD disdplay. As you can
see, I hope , in the left corner some parts of the VFD is missing and the
white color on both ends isn't a good sign.

I bought new condensers and VFD of course, and now I wait for this new
parts.
