Sony 8-301W Picture Tube

[Jonathan]

I pulled my Sony 8-301W that has the B+ to ground short. Unsoldering wires and testing for shorts, I find the short is in the picture tube. I cannot tell which pin is which, but one pin is cut. The black wire on the tube socket is ground, the brown wire is B+ (13V). The resistance of the pins where the black and brown wire connect is 4 ohms. Is this the filament? 4 ohms seems low, and with the socket connected to the tube, there is a B+ to ground short of 4 ohms. This blew the original power fuse that was in there. Is the picture tube shot?

The antenna input was two pins, the tabs that connected to either the antenna or 1/8 phono jack contacted these two large pins with pressure. I was getting lots of snow despite cleaning the corrosion. The one pin was screwed into the chassis as the ground, the other one was connected to the the bypass capacitor and resistor. I removed that pin and with a drill made the hole big enough for an F connector. I screwed in the female F connector and soldered everything up. I powered it up and it blew the fuse and B+ was shorted to ground. When the drill bit finally went through the hole, the whole chassis jerked a bit. Do you think I could have caused the filament to short inside the CRT neck? The set worked before without any issues except a snowy picture. There are no VHF stations in my area, and all I ever do is use the RF output from a satellite receiver or HDTV box. Is there anything that can be done?

Thanks.
