has anyone here ever defungus a zenith 851? does anyone know if the glycol is tinted. would it be possible to turn the PJ so the the lenses are facing up in the air. remove lenses, remove the piece of glass the is holding in the glycol, there remove the glycol with a large syringe whip the glass clean and put the glycol back. I would be ok it this does not permanently fix the issue. This CRT is used more for education and fun to tinker with.

any advice would be greatly appreciated

here is a video i found that is similar to what i am proposing

it's been done but I don't recall anyoneever doing it with a Zenith. Curt will know, he's worke on hundreds of those things.
the Glycol itself will be cloudy and contaminated, you really don't want to put it back in.

I have a 6 pack plastic bottles of TechsprayTV coolant (correct 70/30 mix of Glycol &Glycerin) for 6 bucks a bottle , sealed brand new bottles, 36 bucks + shipping.
They're typically like $12. each. Pm me if interested

Easy to do on the Zenith. Pull the tube, pull the lens and C element from the front of the set and clean the chamber out. Also clean the rubber bellows top and bottom of the tube and the back of the C element as fungus collects everywhere.

Funny, there was a near mint 851 at the local recycler that I get stuff from. I passed on it, as I've scrapped most of my 851 parts. Just as I think no one is using one any more, I find a post like this. smile.gif

Grab Dragan's glycol and go to town. Only refill with new glycol when you're sure that the cooling chamber is spotless!
