[TechAssist] Re: Mitibushi VS 4544 Vertical collapse 2nd try

I agree...if you want the proper help, use the proper words.
A vertical line runs up and down, horizontal left to right.
If you have vertical collapse, you need not even mention the line.
I missed most of this thread do to getting cut-off somehow....but on projections
with no video, this should be one of the first checks.
Since projection sets kill the video when there is a problem in the vertical
section...so as to not burn the phosphors, you need to gradually increase the G2
and watch for the line...as soon as you see the line...turn the G2 back.

A "vertical line" is NOT a symptom of vertical collapse
A "horizontal line" is NOT a symptom of horizontal collapse.  If you want to
change the meaning of words, run for a democrat political office.
