The projector is stuck on the blue screen. It will let me change the input but it will still stay on the blue screen even though everything else is on and working.
"blue screen" means: picture is all blue, but there is a signal coming through? Do you see channel logo? Menu? If so, blue CRT or CRT board is at fault. Depends on the age of the set. If set is fairly new, then try to bang on the neck of blue tube with rubber screwdriver hands. Very gentle! While set is working. If you see the retrace lines and TV shuts down then, CRT is at fault. If not, try to play with blue "screen" control of "focus block". Black plastic module with bunch of thick wires attachad to that. Has 3 "focus" and 3 "screen" controls. For each of the tubes. In many cases you'll be able to adjust "blue" down to normal. Usually, those controls are smeared with white paint and hard to turn by hand. Loosen those with little pliers, then adjust manually or via small "phillips" screwdriver. If nothing helps: CRT board is at fault and must be replaced or repaired. In this case you won't see any characters on blue CRT, just solid "blue".
