        check if there is audio going to the TDA8922. Maybe the mute is on somehow, no VSS, no oscillator, something open in the output, etc.

            IC713 has a 0Ω resistor (R897) across pins 6 & 7, IC 715 pin 6&7 are connected together (section of ic not used)

                That's what I thought it could be mute somewhere so I am looking at Q256 and Q257 as well as the IC724.I am still waiting for my oscilloscope. I already did replaced the TDA8922 that from China it could be faulty that's why have the same problem no audio output.

                    Yamaha MSR400 - Powered PA Speaker
                    by sukaht
                    Hello everyone.
                    I need help with my Yamaha MSR400 - Powered PA Speaker that I bought it used recently.

                    It is power on, and sounding good / working perfectly fine. However after 3 - 5 minutes, the heatsink is starting to get warm, and it smells burning a little bit.
                    I did tried multiple times on different day, event the speaker is not playing any song (input does not connect to any source, and the volume level is zero), after it turns ON, 5 minutes later, the heatsink is starting to get warm, and it smells burning a little bit. I am afraid keeping it ON longer than 5 minutes...

                    Switched speaker impedance selector w/ Yamaha HTR-5740 RX-V450 powered on!! Problem?
                    by JimBanville
                    So I didn't realize there was a tiny written warning on the speaker impedance switch on the back that said moving the switch with the power on "may damage the unit". I actually switched it multiple times, listening for any possible audible changes. It wasn't until later I saw the tiny warning. I haven't noticed any issues though. Can someone please look at the schematic and tell me what damage I may have caused? Thanks!!...

                    Does anyone happen to have a schematic for the amplifier for an Electro Voice SXA series 100 or 250 powered PA speaker?
