Samsung coolant question
 

I have a Samsung PCK520R projection screen tv. Coolant has leaked
from at least one of the tubes. I have cleaned off the pcbs. There
was very little damage. Still I removed some components to get under
them and I neutralized the coolant deteriorating effects with an
amonia based cleaner - a recommendation by NAP, and the
set works great. This is not a customers set, but is my own. If I
missed some damage, I will eventually know it! I found out that
some of these models had problems
with coolant leaking due to heat expansion and the official "fix" from
Samsung to keep this from happening again, is to install special
expansion chambers on each tube. Got 'em. Problem is, I dont see
any access holes on the lens assy's to refill the coolant through. No
plugs, screws etc. Any suggestions? Ive looked in a manual for a
similar Samsung set, (not a Sams manual), and it doesnt say a word
about the procedure. Also, the lens assys have a grey bladder on
them. Are the bladders supposed to be extended inward toward the
center of the tube? or outward once the coolant is replenished? I
work for a TV shop in Mpls, and this is a first for us. Any help
HIGHLY appreciated.
