Thanks for your input. I've not noticed any brightness change in my
25 year old KV-1943 (19") set. Yeah, its over-scanning enough that I
miss most of those moving news banners that go across the bottom of
the screen, but that seems to be the only degradation. I didn't know
about the 30000 hrs. MTBF ... at 8 hours a day use, that equates to
about 10 years service.


If you replace a few capacitors the overscan should be taken care of, those
old sets were very good in their day.
