I had the same problem with mine. Turned out to be a bad solder connection on the Printed Circuit Board on top of the power transformer towards the rear of the reciever. If you flex the board by the connector going to the display you might see it come and go. I resoldered the connections and now all is good.

HI, WHEN I TURN UP THE VOLUME THE DISPLAY SAY'S PROTECTOR POWER OFF AND THEN IT WORKS TILL INCREASE THE VOLUME THEN IT COMES ON AGAIN. ARE THE SPEAKERS TOO SMALL??


disconnect all speakers and try volume on its own.Then try one speaker at a time and increase volume this will help you if one speaker is bad.If unit acts up no matter what you do ..Then theres a good chance you need to send it to a shop .Try to find one thats sony authorized..thanks

Low sound at high volume


Hi,

THe problem is with the variable resistor present behind your volume control knob, try replacing the volume controls variable resistor, this must work fine... this is a common prblem for all the music equipment that has knob control for the volume....

This resistor can be replaced with your product warranty, contact your seller for the details regarding warranty...No need to woory about this, this is a sommon problem for most of recievers

When you change the selector switch, do you hear the relays inside the unit? Is your muting button activated (found to the lower left of your volume knob)? Do you have speakers connected to A or B or both?
