FL OFF could indicate a problem with the power supply or the cooling fan inside the receiver. Try unplugging the unit to reset the error code. If the error persists, the receiver needs to be serviced. If the Pioneer VSX-90 is still under warranty (1 year), contact the manufacturer. Otherwise, decide if it is worth fixing (including the shipping costs and minimum service fee).

I wish that I had better news for you. (There are service manuals available for sale online. I know nothing about these vendors.)

You can take it to any audio technician locally

..

To perform a reset on your Pioneer VSX-S520 using the remote controller, follow these steps:

1. Make sure the receiver is turned off.
2. Press and hold the "BAND" button and the "STANDBY/ON" button simultaneously until the display starts flashing.
3. Release the buttons and the display should stop flashing.
4. The receiver is now reset to its default settings.

If the "Fl off" blinking red light persists, it could indicate a problem with the receiver that requires further troubleshooting or repair.

That symptoms means that the unit has serious internal issues and must be repaired.

dosent help ti Hold "Enter" and "Advnc. Surrnd" buttons on receiver at the same time.???

Press the "home" button on the remote, down left for the arrows.
Then go trough the menu with arrow up/down, until you find "FL DEMO", then press OK, and switch to DEMO OFF :)

Usually means the unit is locked in protect mode. Try holding the advanced surround and power buttons to see if the unit will turn on.

With the receiver off, press ENTER + ADVANCED SURROUND keys continuously for 2 sec. and it will tell you the fault it encountered. Even if it has a short, it will still protect the speakers; however, it is still a good idea to disconnect all speakers before doing this.

Hold "Enter" and "Advnc. Surrnd" buttons on receiver at the same time.
