Question about Audio Players & Recorders
Home theater or amplifier has inbuilt protection circuit to monitor output signal of amplifier as well as speaker impedance that are hooked with amplifier. If any problem occurs, protection will activate and shut down amplifier to avoid further damage (or expected damage) in amplifier and speakers, same time display error code as Protect.
In this Sharp HT-X1 system, one of speakers is defective and causing Protect activation because home theater is working up to 20 volume level.
Please unhook all connected speakers with system, turn on and increase volume level and monitor does it go to protect mode? If yes, them amplifier has internal problem like dry solder joints in amplifier output section etc.
If amplifier stays OK then lower the volume, hook one speaker at a time to test protect error, found good, unhook it and put other speaker until you see protect error with any specific speaker that is bad.
Hope above info would help you to diagnose problem.
let me know further question, if any.

Many DVD discs are encoded with copy protection. Because of this, you should only connect
your DVD player directly to your TV, not to a VCR. Connecting to a VCR results in a distorted picture
from copy-protected DVD discs.
