Got this one in for a PS opto and convergence. I wonder if these sets are
needing coolant changes like other models from Philips. I can see no
contamination but the set is in an application where they need it to work
reliably and getting to it is a chore. If they tend to need it, they would
prefer for me to do it while it is in the shop than have to pull it again in
a year or so.

Does the Green and Blue coolant go bad on these?
