Well I got ready to watch a movie on my Portacolor, but unfortunately the picture never came up. I did hear the high voltage come up, have sound, but no raster at all. Static on the screen felt normal, but don't have a high voltage probe to confirm. All tubes filaments are lit including the crt. I can hear the vertical circuit running, because I can hear it change when I turn the V-hold through it's range. I thought maybe I turned the brightness down while dusting, but that did nothing. Wiggling the tubes did nothing. No strange smells, or burning smells. Set worked great last time I used it about a month ago, and didn't even do the color change problem. Seems like something went open. I don't have a schematic. Any help would sure be appreciated.
Thanks!
