Fickering...

[freakaftr8]

Hey guys.
Well, you guessed it, already having issues with my ctc-16.. It seems that a week ago I had some flickering of the screen, especially seen on a black raster, like before the movie starts os between commercials. It is a bright area of the screen, gets brighter in areas of the top or bottom with a hint of retrace lines. This will flicker is on the top or bottom of the screen or sometimes the middle. It's odd, it almost looks like voltage issues as the area will move, up or down then go away. Thought at first it was the transformer as it feels warm to hot at 1 hour intervals. Havent rechecked tubes yet.. I recapped the set already. Tonight I could swear I heard a faint humming sound coming from the set. These look like 6" bars of bright areas flowing up the screen, flickers, then moves to a different part. Any ideas? I also noticed that the top of the screen, white letters or images, but mainly noticed with letters are more out of focus than the middle or bottom of the screen. Dont think it's related as the set has always been this way, but looks like its getting worse, focus has no affect...
