I'm not stupid NA.
The width setting was naturally already at MAX, but the capacitor which deals with that aspect of the system was leaking or slowly burning, or something deadly.

Actually, now that I've thought about it, I guess it did eventually explode a day or two after the screen was down to half-width and thusly super-bright.
I do remember finding half a capacitor sitting on the circuit board when we cracked 'er open later. And a split/peeled top half fell out.
