When I worked at Genicom, they had a printer refurbish department for "all
brands" and I saw various Epson, etc. printers going out that looked just
like new, and I saw them coming in with the yellow discoloration. I asked
one of the guys how they did that, and he said that they painted the covers.
The discoloration is caused by UV light exposure, which in turn comes from
fluorescent lighting. It won't happen under incandescent light, but all
offices have fluorescent lighting.

And exposure from Sun. I have many items that are discolored on one side,
where something was exposed to a window.

Or just general dirt.... See below for an embarassing story from a
non-smoking environment....

OK, the embarassing stroy. When I was at Bristol, I had a VT102 on my
bench. The display contrast and brightness were falling off, and it got
to the point where it was only marginally readable. I got out the
printset (with my hand-drawn diagram for the later video board..),
started checking volages. All looked fine. Looked at the waveforms round
the video amplifier, looked fine. Plenty of beam current too....
After well over an hour of checking signals and getting nowhere, I
cleaned the screen....

I'm going to give names to all the ICs ever made. It'll hopefully make
them more friendly and then maybe my designs will start working. More
people should give components personal names.

I have a photocopier like that, you can see exactly where it was hit by the
sun over time.
