That sounds more like lubrication for the bearings, or a belt drive.
Solid state circuits are not effected by down time. I'll double check with our chip design son when he comes to dinner tonight.
That would be mechanical parts and bearings again.
UPDATE: Checked with digital chip and circuit designer son and based on science and engineering, a solid state circuit board will do exactly what it did the last time it was powered up unless it was damaged in the mean time.
Some good points here. It's true that, although the TV had no moving parts, this was the early 70s and there was a picture tube. As for the turntable and line conditioner, neither had been used for a while (obviously), but the TT's motor is the more likely culprit. But I'd done the proper lubrication already, so that
wasn't the issue. Also, CD drives have moving parts.
As for SS circuits, I do
note that my system tends to sound better after it's warmed up a bit, as opposed to running it cold. If we're talking an extended period, the capacitors are empty and need to be recharged. I recently reinstalled my previous preamp while the main one was out on repair. It sounded pretty harsh for about half of the first CD I played, but settled in; it had been unused for about 7 months.
I'm no scientist but I think there is something to the idea of running components periodically as far as their health goes. A plasma TV has phosphors, just as a CRT does, so maybe there's something in that. I don't think Pioneer's admonition is mere boilerplate copy, though I don't know how electricity interacts with the circuits and wire exactly.
