Having problem with focus on rebuilt 9500LC with 9 month old lenses. The image from the red gun has gone out of focus on the left side of the screen. The green lens has gone out of focus on both sides of the screen. When looking directly into the lens, The tubes appear to be in focus. Adjusting the front lens element to its maximum and adjusting the screws for left-right focus will not bring it back in. Lenses are all clean. Any ideas? Thanks

Remove the foam surround from the lenses and peer inside with a flashlite; look in either side of the aluminum casting for the green CRT and do you see any steel pins sticking out the sides of the casting? If visible they would be an eight-inch in diameter; they are the scheimpflug pivot pins and should not be sticking out. If they are out then they must be reinstalled and crimped into place or you will never get correct focus.

No pins seen. Problem is worsening in that now all around outer edge of screen is fuzzy and only center especially on green lens is in focus. Would this be some sort of electrical problem?

Perhaps you just need a thorough setup of the unit; try adjusting the front lens barrel for green, it is edge focus.
