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.


They used a lot of electrolytic caps in that set. Its been a very
long time since I was in the back of it. About 10-12 years ago, I
replaced a cap in the "power ON start up relay" circuit. I didn't
even have an exact match .. just fished something close out of one of
my junk drawers, and its been working fine ever since. After 25
years, I imagine that most of the electrolytics will be bad. I think
manufacturers only guarantee them for 3 to 5 years service (at least
that's what I've found for computer grade 'motherboard' caps).

Thanks again .. after I fix up my KV-27EXR15, I'll give the KV-1943
another look. They've both been great sets.
