Mits update
It had a shorted video driver transistor, so now i have video.
but a new problem,
it is now 1 inch short of horizontal scan on right side.
when i get all the bugs out this may be a nice tv.
it sure has many new capacitors now.
lol
the width control does nothing.
more tips please.
Thank you,
Larry
