Time to check voltages against CRT datasheet or schematic.

It does have a service switch on the back which I can't tell if its in the normal position or if its in the service position.

Also I don't know who made this set for J. C. Penney or what the model number is so I'm not sure if I'll be able to find any service data on this set.

The set is a Panasonic.
If you have audio ( hiss) but a total black pix you have a video
problem. Try cleaning the service switch, I thing it has one.
Also try turning up the G-2 a little. After that it gets "interesting".
Post a few chassis pixs also.

Yes it does have a service switch, but it's only accessible with the back cover off oddly enough (it only has a small slit in the cover for it).

Is this a fairly early solid state set like my Sylvania is?

And what do you mean by it gets "interesting"?

The set has no crazy circuit designs so easy to deal with. You may need
a manual, what is the model number ?
Most likely set has low G-1. Normally it adjusts from abt 200-800 VDC
with abt 400 V for a normal picture.

OK So I finally was able to get my workshop put back together after it being torn apart for almost half a year because of mold problems due to water infiltration through the foundation of my side of the house (the part of the house where I live in/use used to be an old detached garage that the previous owners of the house had built in and made part of the house, but never properly sealed the foundation or the cement slab from the garage).

Anyways I finally got this set torn apart and I found a few curiosities in this set, it seems this set may have had an ultrasonic remote control unit for changing the channels as I saw what appeared to be a motor attached to the tuner assembly that is geared so that it can control both the UHF and VHF tuners, and the TV also has a vacation switch on it which I thought that was something that was more on Tube Powered TV Sets and not Solid State Units?

Another interesting thing is that this unit is completely modular, as in it has removable/replacable modules for making this set work, another interesting thing is that the Audio section of this TV in spite of it being all solid state uses an audio output transformer for the speaker (which leads me to think this TV might actually be late 1960s or very early 1970s).

Its also very filthy inside the set, also I can't seem to find the G2 control in this TV.

Pictures of the inside of this TV posted below (finally).
