Subject: [TechAssist] RCA CTC169 proj. lense- is it algae or burn on CRT
face?
I have a CTC169 projection in the shop that I replaced the HV splitter.
Now I am cleaning the CRT lenses and I found the green one to have a
smear look to it on the CRT face. The coolant does not seem to have
bubbles or things floating around in it, but it looks like there is
algae on the CRT face. Either that or the face is burned. I have
included a link to a photo I took of the CRT so maybe someone will be
able to tell.

I've only done a coolant job on one projection, that being an old
Philips set, so I'm not real familar with the symptoms. I didn't notice
any problem with the picture when looking into the lense before I
removed it to clean. Is it worth ripping it apart to change the coolant,
especially with RCA not providing new gaskets? Will I have to do it to
all 3 CRT's to even up the brightness of the picture afterwards (red and
blue don't have this problem but may look worse than a cleaned up green)?
I've already told customer $250.00 to change the splitter. I'm afraid
he'll want to cancel the whole job if I tell him more money to change
coolant. How much should a job like this be worth, with new HDTV
projections, plasma, etc entering the scene?
Thanks for any replies.
