Both. Most monochrome LCD's are blue-green, low contrast

Are these really *scan* lines or *retrace* lines
(scan lines are at a very shallow angle; retrace is typically
much steeper)?
Are they always on the same place in the picture?
Can you suggest search criteria to find these other
comments (not that I am *doubting* you; rather, looking
for other descriptions to guesstimate what is happening)?
*Or*, can you email me a photo of a screen shot? :>
Really? I hadn't realized that there was
such a "common
failure mode". But, I am unsure of what you are describing...
Is the lower third of the display a "solid white band"?
Or, is the *retrace* visible on the lower third of the
Like one or two scan lines that are always white. A few years ago
when I researched (probably on Usenet or repair webs) there were
several others with the same problem. I interpolate. I was hoping
to find a monochrome CRT instead of an LCD.
Color isn't a requirement. Monochrome LCD's are poor quality.
Poor quality or low res? I once had a tiny handheld mono LCD TV from Radio Shack made by Casio. But have you told us
what's driving this display?
I would think that would quickly reduce or expand your options.
I'll drive it with whatever I need to in order to get the
images I want on the display. I would prefer NOT going in
through the front end (RF) but can probably bypass that.
(I'll have to look through my Sony docs to see if I have
a Watchman service manual or if that is just too old for
my collection :< )
VGA? Composite from VGA? Many folks don't
realize how low-res
is composite. Mounted on your arm or your eye?
Mounted in my *pocket*! :> It is only an interim solution...
sort of a backup "console" that I can glance at when/if things
aren't working properly. The watchman package pushes the limit
of what I can stuff in my pocket comfortably...
