Question about Sony DAV-C990 System
This is not good news for you. Most often when you get this protect mode on these, it is the amplifier circuit that has gone bad. Sometimes it is the power supply that causes it, but more often it is the amp.They are very difficult to troubleshoot, so you really should just take it to a service center for repair, unless you have some good electronic troubleshooting skills, then you could take a crack at it yourself. But it does have some serious electronic problem that is not an easy fix at user level, It will require a technician with the proper tools to isolate the problem and repair it.
I am happy to offer you more help if you need it, I may even be able to get the service manual for it and email it to you if you want to troubleshoot it yourself. Just let me know.
