|
|
My focus rings on my xg green tube do not rotate. Their are 2 per tube and they appear stuck. I loosened the bolts as per manual but they still do not move. What can cause them to stick? The red and blue move but the green will not. I need to try and fix the green!
How do I fix this?

Take the magnet cluster off the tube, and loosen them with a small screwdriver. I'm guessing some silicone got between the layers of plastic. If not, I've got spares.

Maybe I am confused or I consfused you. The part I am talking about is on the lenses. 2 dials for each one to set focus for screen size. Not on the tube but 2 plastic dials.
I never got my focus real good. So I think I should adjust these a bit like per the manual but they seem stuck.

Take the lens off the tube housing, and try getting it to move on the bench. If you play with the lens focus, you will quite likely have to go over the convergence again.

The rings are on the LC chamber between the tubes and lenses. Maybe they are stuck from heat? They are not attached to the lenses. Seems strange they do not want to move.

Oh i got ya, those rings. They are for lens flapping, you need to loosen off the screws that hold on the lens, then they should move, if not, remove the lens and they should move.
