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.
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.
