This is an indication that there is an overload problem in the output section of the amplifier. The overload could be thermal or electrical The overload circuit has built-in protection to help keep the amp from burning itself out. disconnect all speakers and cables from the unit and power it up. If the problem still exists, it is internal and will need to be repaired bya professional technician. If the problem goes away, check for shorted, crossed wires to your external speakers. Try different wires and speakers.
Hope this helps.

press setup/configuration on your remote you'll get configuration menu, then goto 'speaker configuration' check if the subwoofer is on, check that front speakers and others are set as small. There also could be subwoofer mode settings, remember current setting and try to change it.

Try using your headphone, if the sound comes out, it means no problem with the pre-amp, then the problem is power output

most of the receivers come with a cooling fan inside see if its working they usually work when you turn the volume up,, if its working that means you are playing it to loud if you lower the volume a little it will play just fine..( if the fan inside is not working thats the reason it goes into protect mode and it means you must have it repaired,, it goes into protect mode to prevent furter damage to the unit or the speakers,,

I had the same problem with my subwoofer unit. I found the zener diode ZD3 was fried. The pic below shows the diode and its clearly tagged ZD3. You need a multimeter to check this before you order anything. This diode should only transmit power in one direction. Its size and spec is 18v .5w zener diode. (that's 1/2 w) It's very inexpensive and the whole repair took about an hour. This is from a Boston Acoustics subwoofer MCS 160
Ok..the procedure is easy.
1) unplug the unit and bring it to a well lit work area.
2) remove the panel from the back and locate the board that is held to the panel by 4 screws and has the ZD3 diode. The pic below shows the diode at the end of my test lead. Note the direction of this part and reinstall the new one in the same direction. Its a simple de-solder and re-solder project. I elevated the new diode about 1/8 " from the board with a small strip of copper. This acted as a heat sink during the soldering and elevated the part above the board to help it dissipate heat later when in use.
3) re-install the board and plug in all the connections.
4) this worked for me and I'm enjoying my sound system again!..good luck0482b949-8492-43a6-91df-0fb2f0e6888b.jpg
