Most video problems on old B&W sets leave you with a lit
screen so probably not that.

No HV will kill the pix. If audio good most likely its the HV
rectifier tube. IIRC its a 1X2 the tube the anode wire goes to.
On GE's the sockets used to corrode, check for green crap
on the tube pins & socket. You can usually detect HV by
putting the back of your hand near the SCREEN, you will feel
the static pulling on your hairs. BTW the socket can give you a shock
when off. The cap on the other end is safe when off.

A bad CRT is also possable. Run the set for a while in a room
with NO light. If you see a very dark image its probably a bad CRT.

Beyond that post the model # ( stamped on back).
Chassis # ( look on tube chart) and maybe a screen shot of
the chassis & a lot of us will try to help.

Well The Model Number of the TV is 9T001

Chassis number unsure as the tube chart is inside the cabinet and I had a heck of a time getting the cabinet apart the first time around, and I forgot to look for the chassis number when I did have it apart.

When I powered it on when I got home from church to see how it worked the audio was perfect minus a little buzzing noise that would come on when you turned the volume control but then would disappear when you jiggled the volume control slightly (more than likely a dirty pot), but as for the picture it was completely blank not even a slight hint of a picture (which you said if the picture tube was bad there would of been a slight picture still and mine has no picture at all which is why I think its not a bad picture tube but something else associated with the video circuit e.g. bad video amp tube.)
