Initially it booted and ran for a while until I

The last time it responded to the power switched, components powered up
and the FDD started operating. Then suddenly everything stopped like the
plug had been pulled.
Now it does nothing (apparent) when it is switched on.
The rainbow has a number of LEDs in the back that it frobs while booting...
Do any of them light up?

Thanks. When I first got the Rainbow, I asked here about what to look for before
powering it up and was told about Rifa caps and what look/listen
for.

Maybe I need a little clearification.
When you turn the switches off, it boots?

I don't have a list (I just got a pair of Rainbows last month) but
given the era of manufacture, I'd be looking for Rifa EMI filter caps
by the power inlet. I've had those fail in BA23 cabinets and in a
Commodore D9060 hard drive, and a TRS-80 Model 4.
I eventually threw caution to the wind and just powered it up and I ran
it for
15-20 minutes. The PVA in the monitor was really cloudy, so I didn?t
use the system anymore until I removed the PVA over Christmas. I was
testing everything after that and the system was booting up when the power
all switched off like it had been unplugged.

This is totally different than failing/bulging electrolytics.
