BTW, If indeed you see the on screen menue and volume control bar the

problem is beyond just that coil. the coil supplies the drive signal
to the
base of the horizontal output transistor, allowing it to drive the
LOPT and
develop the HV and other derived sweep and supply signals. You will
need to
troubleshoot the video processing circuit including the jungle ic to
find
the actual cause of the lack of video to the crt.


Hi Art,

So, I removed the coil and cleaned off the small amount of glue that
was between the coil and the board and then resoldered the coil to the
board. Indeed, the problem persists, so what you say seems like it may
be true. Any suggestions as to where to start in the video processing
circuit?
