I'm almost afraid to hear what I think it is. But this has probably covered before, and my database went south a few weeks ago,and I'm rebuilding. This set will go black and then back to Video, black and back to Video every 5 to 10 seconds. Does not loose HV. I believe someone mentioned K circuit on CRT. Can someone give me a quick rundown what my options are, short of changing the CRT.
