Motorola 19k14wa Possible Arcing?

Hey guys, I powered her up tonight and noticed a funny hissing noise as well as some horizontal waviness which went away after a while, and the set seemed fine. I turned it off and waited a while, then with the back and HV cage off I watched it power up in the dark and didn't see anything funny. it did hiss a bit but the picture looked okay upon warmup. All tubes test okay (at least around the video/horiz/vert section) but I haven't tested the HV rectifier.

Only other thing I noticed was a blue glow in the damper diode (12AF3), but that shouldn't be a concern right?
