It' sound like you have a bad crt, to make shure, just disconect the red crt baord and green crt board next to it and move then so you can try the red crt board on the green crt. If it does the same problem in witch I realy thought it's your video or hight voltage sounce on that board. If you get no problem well it's your crt.
I can almost garranty it's your crt.

GREEN CRT OUT OF FOCUS


The individual lens have a lug nut that when loosened allows the lens to be turned-----cover red and blue lens and call up the convergence grid---from the rear adjust that lens until the green lines are in good focus(can also do the red in and the blue if needed)


You will get no more advantage as the manual focus controls on the splitter block have very limited range.


when done carefully tighten the wing nuts on the lens back tight.

I have a Mitsubishi WS-65807 Projection Tv and while I was watching a program the picture went to a black screen. The audio works fine and when I go to the Menu it shows up fine. Any input as to the...


Thats usually a vertical issue since the menu still works. I would check the solder on the vertical IC and also the Vertical yoke plug pins. Often solder can develop a small crack around the pins and resoldering will usually fix the issue in most cases. The other item could be a leaky CRT has dripped some coolant on some of the components in the vertical circuit so I always check the board for any sign of a clear sticky residule on the boards which indicate dripping CRT coolant.

Red and blue overlap shadowing


Sounds like a convergence ic problem, normaly i tell people to replace the ic's but in your case try to re-solder the pins on the ic first, you may just have some pins broken loose from the board. Locate the stk392 ic's there will be two of them located on a heat sink, unplug the tv and get to the bottom side of the board and re-solder the pins. if this does not work, then replace the ic's

Red convergence wont move


if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........

convergence STK have nothing to do with the red being blurry

Mitsubishi ws 65807 RED CRT


What I usually find on sets like that is that there is a loose solder joint on the CRT board itslef. You must get to the bottom of the picture tubes, pull off the CRT board from the red CRT and examine all solder joints on that board. Chances are one or more will be cracked, and resoldering all joints on the board should clear up your problem.
