I hooked up the oscilloscope and verified the X/Y Out voltages of the board, and it all checks out.
I moved to the monitor, pulling the Deflection and Regulator pcbs. There were obvious cold solder joints on the Deflection pcb. All headers and major resistors got new solder.
F700 was blown. (I'll need to order a replacement)
Q707 & 708 are good.
Q704/5/6 all test good, but the vector faq says not to trust your dmm when checking those.
Q701/2/3 also test good
I also checked most of the diodes and resistors in that area, and found them within specs.
What's the next logical step? Should I replace Q705/6 and the pico-fuse at F700?
