[Histonet] CRYOSTAT PROBLEM

[Lakshmi Kammili]

Hi all,
We have a old cryostat (Microm h505 model). It was making some sudden vibrating noises for a little while and then smooths it self. There  are no temperature alterations every thing was fine but suddenly it stopped working, no display more looks like dead :( 
I tried calling the service company which serviced before but I guess the company is no more in service (as it was a very old machine). I am very new to this maintenance issues , I would be glad if any one of you can help me in suggesting a company or person whom I can talk about the issue or some one who can come and look at the  instrument and suggest the best advice . I assume probably some electric motor is dead inside. 
Any advice will be really helpful.
Thank you,
