The heaters are glowing just fine in the CRT. The tube is a 2007 Hawkeye rebuild with low hours on it. The set was working just fine until this happened. I really think it is an HV problem. I will need to pull the chassis to troubleshoot it properly. I did look at the HV rectifier socket and cup. There appears to be no damage to either. The 1500 ohm resistor across the HV rectifier socket is pretty cooked. It measures 2K and looks like a ferrite bead. The body is black and none of the color bands are visible. The inside of the HV cage is fairly clean as I cleaned everything when I restored the set eleven years ago. This set has performed well while I have had it nothing beats that Zenith color and build quality. For now I will have to put my 1956 RCA 8" B&W set on top of it until I can get it fixed.
