How can I test R105 for the degaussing coil? I don't hear the "sound" of the degaussing when I power up and I wonder if it is not working well. I measured the voltage to the coil and it appears to reach about 50V for less than a second. I was using a DMM where I fixed the range so I could get a reading as quickly as possible.
My PTC is kind of cracked open and very hot to touch![]()
Got a K7000 with fluctuating/unstable/incorrect B+? Don't overlook the easy things...

Are your G2 and focus wires connected backwards?So I decided to swap the tube with a donor Sanyo TV that I had. The tube swap went fine, I think. I kept the old flyback in it and the image was still dull even with screen, brightness, and contrast all the way up. No retrace lines are visible with the screen turned all the way up. Same symptoms as before, so I guess it's a chassis issue. I found the horizontal width coil was out of circuit, reflow didn't change anything. Put new flyback in, same exact symptoms. At least now there's no arcing.
Image is displaying, it's just dull, out of focus, and mostly distorted.
