Next look at the two vertical output transistors Q201 and Q202. They are both bolted to the flyback cage. Both are also type 2SD1138 (this type is also used on Electrohome G07 monitors).
Next check the integrated circuit IC401.

Ken,
To piggyback off the OP (and my apologies, but it is related to the same exact monitor PCB) I have this monitor, and the fuse at FS01 has been blowing. I replaced the HOT bottle cap as well as some transistors and resistors, and I still get the same thing. The flyback has a pinhole I patched with epoxy and I did the cage cutting mod. Any suggestions?

I do not know what is going on!!!
I chech every cap,resistor and i change the ic 401 and the first time i power up the monitor works fine.
After 2 hours i power up the monitor and same thing vertical collapse.
I will try tomorrow to change q201 and q202 even if i test as ok.
infrared:
Finally i change Q201, Q202 and monitor know works fine.
Ken do you know in case i need a flyback in the future where can i buy one.
Ken Layton:
Check with Chad at ardacecup.com for a flyback.
