Question about Sony DAV-C450 System
I have a Sony home theater model HCD-C450: The DVD player will stop playing and the message "Protect" is displayed on the panel. I then have to turn the play off and turn it back on before it will play the DVD
It is possible that your system is gettting overloaded and makes the sfety cicuit switch off . This is the protecction circuit to prevent further damage and fire within the system particularity when the output or power is shorted. Check from the speakers for short remove and test . Also use a multimeter to test for short in the output drive. If so disconnect and see if the protect releases. Then you must replace the outputs. Check also the protect cicuit for a false alarrm due to wrong biasing. Hope this advice helps to figure out. Good day
