I was away for a few days for the Memorial Day weekend, and like every time I go away, I had all my A/V components unplugged from the outlets. Perhaps this seems odd, especially since I use surge protectors, but I lost a computer to an electrical storm last year, and I don't take any chances now. Anyway, I got home this evening and plugged in the surge protectors and then turned on a few components around the house. Everything seemed fine. Then I turned on my Sony STR-V444ES A/V receiver a few hours later, and the display said "PROTECTOR Please Power Off". Of course I turned it off right away. Then I unplugged the receiver for about a half hour, plugged it in, and tried it again, and again, I got the same message. I saw no smoke and did not smell anything unusual the first time I saw the message. At this point, I have no idea what might have gone wrong. I've never had a problem with this receiver. For now, I have the receiver unplugged. When the receiver functioned normally, I would hear a click when I turned it on and a second click (relay?) a few seconds after turning it on. Now I don't hear the second click. I hear the click when I turn it on, but then I hear nothing and the PROTECTOR message is displayed. Could the power supply have been fried somehow? There is one other thing I should note. I have a small desktop fan from Brookstone standing on the back edge of the receiver (it does not cover the grill on top of the receiver at all). I've had this fan ever since getting the receiver back in September 2000. The fan speed can be adjusted. Whenever the fan is unplugged and is plugged back in, it defaults to the maximum speed when you turn it on. (If you lower the speed and turn it off, but do not unplug it, it will remember the lower speed setting when you turn it back on.) Anyway, my ritual after plugging everything back in is to turn on the fan and adjust the speed (the maximum speed is not necessary) and then turn on the receiver. The fan and receiver are plugged into the same surge protector. The fan is working fine. Could the fan somehow have screwed up the receiver? For what it's worth, the fan is connected to a 6V AC adapter, which is plugged into the surge protector. Has anyone else observed the PROTECTOR mode with the Sony 'V333ES, 'V444ES, or 'V555ES? I know that this is a fairly common problem with Sony's DE receivers, but I have not heard of it happening often with the 'V' series ES receivers. Anyway, I am prepared to box up the receiver and take it to a local Sony authorized repair shop nearby.
