Dear list,


Ch3 PMT intermitently dies on our LSM510 system. After 2-4 hrs
of powering on, all image pixels turn to  zero intensity no matter
what are laser power, pinhole, filter, and gain settings are used.
Cold reboot does not fix the problem though no error messages
are reported. The single fix so far is to let the system cool down
for several hours then it is again working for few more hours.
Surprisingly all cooling fans are spinning normally as well as  room
conditioning system.




We are off service contract so any feedback/advice what could
be wrong and how to fix it is greatly appreciated.


Thank you,
Arvydas
