RCA PROFESSIONAL SERIES STAV-3880 AUDIO/VIDEO RECEIVER SHUTS OFF

    Receiver has worked fine for long time. Just in past week started making odd noise randomly through speakers. Now. stays on about 60 seconds and then powers off. Disconnected speakers. Same problem.

    Same problem here... The strange thing is, even when shutting off the power normally, there was never any "power off" notice that I can recall, which leads me to think I am overlooking something. It's driving me mad.

SOURCE: receiver shutdown

There is whats called a protection circuit inside this receiver. This is what is supose to happen when the receiver detects a short in one or both of the output stages of the amp. Unless you have a service manual or have the know how to work on solid state receivers, my best advice is to take the unit into an authorized Yamaha repair depot and have them take a look at it, as they can hook up the receiver to a set of load resistors and run the amp to max capacity and see when the amp section of this receiver starts to clip and that will give them an idea of where your problem is. I'm afraid there is no fix that an end user of this receiver can do. Good Luck

SOURCE: Immediate shut

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck

The problem might be caused by two major circumstances. 1)Touching wires 2)Overheating. I suggest you unplug all wires connected to the amp then turn on the amp. If it gets turned on then we know that the problem is that you have touching wires. If there is a short circuit somewhere, get rid of it. The ventilation is another important issue that you have to pay attention. It simply causes overheating.

SOURCE: RCA STAV-3880 RECIEVER FOR CHEAP. I DOES NOT RECOGNIZE DIGITAL

I have found that on some units you unfortunately need the remote for more advanced settings. Sorry man.

RCA Stav-3880 turn stereo on goes to full volumn


Take the batteries out of the remote control, then apply a piece of black tape over the IR sensor, Unplug the power, wait a few minutes, now power the unit back up, does the unit still have the same volume high symptom? If so, remove the tape and see if the unit responds to any other commands(other than volume) from the front panel. If it responds to the panel controls, the processor is most likely good. very seldom is the IR transistor bad, if it is no input command will work.

''Power off ''flashes ten times after the receiver is turned on.


Most often it will require an output IC, but I have seen it be a bad ground or a transistor in the protect circuit.
