Follow these steps to try to resolve this issue: IMPORTANT: It is recommended that all car video and audio installations be performed by a … Took me a hour to figure out that a spiked foot on one of my surround speaker stands had pierced the speaker wire. ). I have sony 7.1 stereo receiver that's about 3 yrs old. Last time this happened to me the receiver would shut down only when playing 5.1 material at a fairly high volume. Then I have the receiver drive with 4 speakers and even 2 speakers still got cut off when the volume turned high (arround -10DB or -7 DB). The receiver will automatically turn off after a few seconds. If your speakers are 6 or 4 ohms your receiver is going to shut down at high volumes to protect itself. Even if your speakers are 8 ohms they may dip at certain frequencies which may also shut your receiver down if played at a high volume for long enough. Is the stereo not appropriate for the speakers after all? If there is an explosion, causing the volume to get louder it goes into this protection mode and shuts off. Sometimes it will only take one or two speakers that are not rated at 8 ohms to shut down. At least it was a simple fix. I was about to throw out a Sony surround sound receiver I’ve had for years because it would flash “PROTECTOR” on the display after being on for a few seconds, and I’d tried everything I could think of (cleaning, making sure no bits of wire in speaker posts, leaving off for hours or days, etc. i.e when watching a movie with regular dialogue it will work fine.

I have a problem with my new Sony digital receiver. Unplug the AC power cord (mains lead) and then plug in the cord again after 30 minutes. Many modern receivers have "protection circuits," bits of specialized hardware that recognize dangerous levels of volume and shut your hardware down, like a digital fuse. Whenever the sound on the movie gets loud it shuts off and flashes "protect" on the screen. Radio/Stereo turns off when Volume is tuned Up. Could it be a problem with my wiring job? recently it started to go into a protection mode when volume reaches a high level. I checked and make sure no wires touching but still did not solve the problem. My goodness the internet is great. When I turn on the volume around -10DB, the receiver got cut off. This also happened when I use my Awia stero system. My Yamaha RX-V659 receiver shuts itself off when I have it at somewhat high volume (-10 to -12 dB depending on sound mode) and there is a sudden loud noise in a movie (like an explosion or gunshot). It may seem at the time to use old or existing wiring without verification to save time, It rarely works out that way. Try running the auto speaker setup utility (plug in the calibration mic and it will prompt you to start) at a loud volume and see if it shuts off when addressing a specific speaker/make sure all speakers produce audio -- if it does that speaker is your culprit. I have Onkyo SKW-540 7.1 HT speaker set (powered sub) but I don't have the back 2 speakers hooked up (so it's only 5.1 setup). when turn back on there is a msg display "check Speaker wiring". I have replaced my battery, alternator, checked my ground, and it still does it. Do I need the receiver or any other additional equipment? Check for "whisker shorts" on all speakers and receiver. The sound is great, but if the volume gets past a certain point (which seems to vary from track to track), the stereo shuts itself off. What sort of mistake am I likely to be making? Ever since I got my Sony headunit which has a built in 45w amp I have been having problems with it shutting off when I crank up the volume to around 45-50 (50 is the max volume) and the bass hits. The car stereo receiver may shut off or lose power if there is an issue with a loose or dirty connection. The receiver is covered and the ventilation holes are blocked.
