Hey Chad.That was quite a haul.On that 46" Magnavox in addition to cleaning the mirror and lens you may have contaminated fluid in the green and blue coolant fluid.It's a common problem with Magnavox projection tvs.Look into the lenses while it's on.You'll probably see stuff floating around in there.A lot of times there is a thick yellow crust on the fisheye lens and you can't even see the picture on the tube you're looking at.What it is is some type of mold that supposedly got in the fluid at the factory.It takes a while to show up.It doesn't respond to red light so the red is not a problem.It's not really a problem to change.You can get new fluid from MCM.You remove 1 tube at a time and take the overflow chamber or diaghram off and drain it out.Then mark the tubes' position on the chamber with an awl so you get it exactly where it was.Take the chamber off and clean everythng with denatured alcohol.You can rinse most of it away with water but the denatured alcohol is needed to kill the mold.Put everything back together and refill.Don't fill the overflow chamber all the way to the top.It will cause it to leak when it gets hot.Just try to get all the air bubbles out of the chamber itself.I take the tube,yoke and all out when I do this procedure.Reinstall the tube and recenter it with the centering magnet if needed and converge that gun to the red.Best to only work on one tube at a time and get it converged before starting the other.Most look fantastic after this unless the tubes have a lot of hours on them.We get a lot of work doing this procedure.It's still happening on newer ones too.Always the blue though.Those big projectors are one used tv I can always sell unlike regular tvs.Walmart is trying to ruin that too.New HDTV RCA projection sets for $899.Right now I can still get around $400 for one though and I don't have to resort to the flea market.Just make a few phone calls telling people on my list I have one.
