Anywho, I said I wanted to do this one from Fromms flowcharts... but it comes to a point (at the end) where I just can't decide on what to do.
Anywho, monitor had no neck glow... followed the charts and tested R1, voltage was about 25V too high on either side of the resistor (167V, 145V). So, next step was removing X701... K, neck lit up, I have a "picture" (no boards hooked up) on the monitor now... Great. I check the voltage again... it's gone down, but still about 15-20V too high... lets look at the two options.
1: Monitor now works
or
2: Voltage still too high
Okay... yeah, monitor "works"... k, but the voltage is still too high...
FWIW X701 was open all the way around.
Anywho, so the screen turns on now, and after I turned the brightness down on the flyback, there's a wavy black/brown spot on the "top" (left) of the monitor... *image attached*
Caused by... bad caps? The fact that transistor is still off the board? Flyback pooping out?
What's my next step in this thing?
