Major havoc trouble

I finished the upgrades to the monitor and it worked geat. Then I had to
change the CRT. The CRT swap was successfull,once again the game worked.
(Yes I swapped with an identical CRT)
 Heres where I decided to leave the game on for about 15 minutes befor I
degaused the monitor while I went to watch the Simpsons,when I came back
there was no picture on the monitor. The spot killer is NOT on. The
gameboard does generate sound,but no picture.Deflection must be
happining because the spot killer is NOT on. What could've gone wrong?
All I did was leave it on, I didn't even touch anything and it worked
great all day before.Any Ideas?
