I'm looking at repairing a Sharp XM-2001N (red tent) monitor which seems to have horizontal collapse. (See attached pics)
I've recapped the monitor and B+ is at 108vdc. There is a charred hole underneath the h-size coil. I added the yellow wire to reattach the coil. Tomorrow, I'm going to check R636 that's attached to h-size coil and probe around in the horizontal drive circuit.
Any advice? Not sure how the hole under the coil got there. Seems like a catastrophic failure of this monitor. Note: The monitor was already dead when I got it.
