I wish I had been able to try that.
My tenant brought in his Sony last summer with no picture.
I got to the IC where there was no signal coming out on the RGB pins and
called Fulton for assistance. Their tech had me measure DC at several pins
so quickly I didn't have time to write it down, then proclaimed I had a bad
CRT --- green gun.
I told my tenant what it needed and of course, a new CRT was out of the
question. I kept in on the shelf hoping to come across some way to get it
working ---- until last month when I finally fed it to the dumpster.
