Re: SGI GDM-5011P CRT Monitor (Sony Trinitron) Help
the only signal that makes any sense in c_sync_2, which is correct for what the horz. sync pulse should look like, but this is entering the monitor, does it still look ok when it gets to ic010 pin 7
so you replaced 60 elect. caps on the D board?
It is hard to tell from those first 2 images, what it looks like is part of one scan line.
I would have thought a similar signal would have been in picture 3 and would have an amplitude of about 3v peak to peak, but it is dc coupled so its hard to know what the ac video signal is at that point. I also see the scope measures 12vdc on pin 37? that seems to be close to the 12v vcc. I would expect the voltage to be more like 4vdc on pin37
