Be carefull of the high voltages inside. The focusing screen is in
the tube. Try cleaning the entire unit. Blow all the dust off of
all of the wiring leading to the tube. Be very carefull NOT to move
the deflection coil. Realignment can be tedious. A TV repair shop
may be able to refocus the tube for you for some $$$.
