Sony KV-3000R greyscale

[freakaftr8]

I replaced a cap on the CRT neck for the luminence. the smear and the dark left got better, the smear is gone, but it's still a hair dark. Im thinking that it is a cap still, when the crt is powered up, it looks like the contrast has been turned all the way down, 30 seconds it gets brighter, and after a few, if I had a black raster, it's usually reddish tinted, then it finally after like 5 minutes the red background starts to level out to a nice greyscale.
