That's got to be your protection indicator. You may have a component starting to fail, although you could check your speaker connections and impedance switch. Get yourself a manual:

yep, that's a bad sign. Chances are it will get worse, and not come up after the "perma-P".
Well, right now it's unknown why is it going into protection. If it's for real safe operation issues, you'll want to correct that as soon as possible. Having a situation that's really trying to activate the protection circuit to save itself, might be stressing the amp.
If there's too much output current, the amplifier can be damaged. If there's a DC instability, the protection will react. You might hear a 'pop' when it goes into 'P' mode.
Look at the recommended hook-up and operation in the manual and know the condition (impedance, functionality) of your speakers.
If there's still a problem, (either) bring it to a shop, or delve.
Delving is not that easy, and the more you know, the easier the job gets.
Chasing down unstable DC operation can be very tricky, especially within a feedback loop.

Happy to say I've solved the problem.
I found the manual and under troubleshooting read that the Impedence
had to be properly coordinated with the speakers. It wasn't. I easily
switched it with a screwdriver (little slot on back above speaker connections).
No more flickering square with P! Plays great.
Great Christmas present!
