Yamaha RX-V377 user manual

No, the Yamaha RX v377 does not have built-in Bluetooth. However, you can connect a Bluetooth transmitter to its RCA or 3.5mm output to enable Bluetooth connectivity.

There could be several reasons why your Yamaha receiver is shutting off after a few seconds. Here are a few common causes:
1. Overheating: The receiver may be overheating and automatically shutting down to prevent damage. Ensure that there is proper ventilation around the receiver and that it is not blocked by any objects. You can also try running a fan near the receiver to keep it cool.
2. Speaker impedance mismatch: If the speakers connected to the receiver have an impedance that is lower than the recommended minimum, it may cause the receiver to shut off. Check the speaker impedance and make sure it matches the specifications given by the receiver.
3. Short circuit or electrical issue: There may be a short circuit or electrical problem in the wiring or power supply that is causing the receiver to shut off. Check all the connections and ensure that there are no loose or frayed wires. Try plugging the receiver into a different power outlet or using a different power cord to rule out faulty wiring.
4. Faulty components: There could be a faulty component inside the receiver, such as a blown fuse or a malfunctioning circuit board. In such cases, it is recommended to contact Yamaha's customer service or a professional technician for assistance.
It's important to note that troubleshooting electrical equipment can be dangerous. If you are unsure about any steps or feel uncomfortable doing it yourself, it is always wise to seek professional help to avoid any potential harm.
