Hi. I have a SONY STR-V333ES receiver in perfect working order for about 7 years. Last week, while watching T.V., the audio suddenly stopped and the display read "PROTECTOR" and "POWER UNIT OFF". I powered the receiver off and back on again within a few minutes and still no sound.
There is usually an audible click heard from the unit after powering up, just before the audio comes on. That is no longer heard. The A+B Speaker select switch also no longer produces the internal "click" when switching speakers.
Any ideas from sony receiver users?
Sony STR-V333es recevier connected to 5.1 speakers
optical inputs from directv box and dvd player
analog inputs from phono and vhs deck
audio has never been played at very high volumes (high enough to force unit to overheat)
Unit has enough ventilation on sides and top/bottom
