i have a 25" K7000. just did a cap kit and installed a new flyback, and in general the picture is fairly nice.
however, the brightness is unstable. when it's initially turned on from cold it'll get brighter and brighter over the course of a half-hour until it's fairly washed out; readjust with SCREEN and brightness adjustments and it looks good. then sometimes it'll quickly go dark (haven't actually seen it do it so i don't know exactly how quickly but less than five minutes,) and need SCREEN turned back up just to see any picture. readjust and it looks fine.
yes, this tube did already have a recent rejuve.
any ideas of where i should be looking?
