I know some of those did use a bulb in back of the LCD screen.I had some that were burned out and I held a flash light on the LCD and see the freq numbers on it.I suppose you can replace the bulb with a LED with a voltage dropping resistor hook to the PS.
I have to fix my late mothers same era Sears set with a blown dial light later sometime with a LED.
Wow 120watts.Don't wake up you neighbors.LOL.

I was able to get into my tuner and found the bulb which it uses, although I'm wondering if I can find a replacement bulb for it or even modify for LED, because its a really small rectangular shaped PC Board that uses a blue elongated axial leaded incandecent bulb like pictured below, and as far as I know they don't back blue LEDs yet, let alone whether or not this system's light board for the tuner's backlight can be modified for an LED or not, because it seems to be a pretty specific design.
