Do you have one of those "Multi-Function Boards" installed in the back side of the console? Typically, these were retrofitted to the system when the platter failsafes were installed.
They are mostly a pain in the ass. The platter failsafes didn't really work well and people ended up manually diabling them by tying them down. (Among other things.)
Another things that causes problems is the "Lights-Up" retrofit. That's the white timer module that holds the lights up at full brightness for the advertisements to play. Again, they are a real pain in the ass. Fortunately, these are easier to troubleshoot than the "Multi-Function" boards. You can replace the white relay/timer thingy and you'll be okay. (Check to be sure nobody's fiddled with the settings on the thing before you go and toss out a perfectly good unit, though! -- Been there! Done that!)
For the "Multi-Function" boards, the troubleshooting may or not be simple. First try replacing the relays on the board. (Swapping them out with known-good ones?) IF that doesn't work, my advice is to tear the things out and throw them in the dumpster! REALLY!
I had a whole series of projectors that had these monstrosities retrofitted to them. One by one they started malfunctioning, much in the same way you describe. (Cycling the power solves the problem until the next show.) Once I removed those boards, almost all the problems we had been having vanished overnight.
If THESE things aren't the problem, might I suggest you try checking (changing-out) relays on the mother board? I can't think of which one(s) they are but I have had several problems with CFS that were due to bad/stuck relays. If this still doesn't work, then you may have a probem in the MB itself. (RARE)
In the few years I spent taking care of projectors, I have found CFS to be one of the most cantankerous automations. Either they work or they don't. Here's a whole cabinet full of relays, wires and switches that does the same things that other compaines do with a unit no bigger than a shoe box.
With CFS, you're usually in a love-hate relationship... You LOVE to HATE them!
