Hello everyone, I'm hoping I can get some help here.

My home theater system has worked just fine for the last 4 years. I have a Pyle Pro PT260A audio receiver hooked up to a DVD player, a CD player, and some speakers. Just yesterday we sat down to watch a movie and no sound would come out. We checked all the connections and everything was still plugged in. We tried turning everything on and off. We tried muting and unmuting it. We tried switching between channels. We tried all the buttons. We tried the CD player too and still got no sound, so we know the problem isn't the DVD player. Is there any reason the sound would suddenly stop working, and is there anything we can do about it?

Thank you in advance for your help!

it could be that everything is functioning normally except the amplifier went into protect mode (disabling the amplifier which would explain no sound) due to power fluctuations or other such things.

PLEASE READ: the below has to do with clearing the warning though if there is an actual problem with your unit (and it trips again) you could potentially cause more damage by clearing it and having it come back than just sending it in for service. while it should be fine to test for this first, i'm just making you aware that there is *some* risk of further damage if something was in fact wrong with your unit and it was not tripped by accident.

i've had this happen on my pioneer and it can be quite the ah heck to deal with given that how to reset such things are NOT public information and generally guarded very closely by repair centers and the manufacturer (since they want you to pay to have it fixed.) on my pioneer there are button press codes (normally hold two specific buttons down) which can clear various tripped states. i've had to do this twice now - the first time i sent it in for repair (since i could not find the codes anywhere!) though this last time i finally managed to find codes (for a different model, though they worked)

unfortunately i do not have a list showing how to clear the function on pyle units. you can try unplugging the unit and pushing the power button down for 30 seconds then plugging the unit back in and starting it up. this can clear some forms of protection however others may require special key code (holding certain button combinations down) to clear. this is for pioneer, but may help you get an idea of what might work (you will likely need to experiment as i didnt see anything come up for pyle when i searched for codes) http://electronicshelponline.blogspot.com/2013/05/pioneer-vsx-821-k-vsx-921-k-vsx-521-k_14.html

if the above doesnt work, it could be a fuse inside the unit. if its not a fuse, it could be an actual damaged part.

It is possible that the Pyle has internal fuses that may have blown. These usually look like this

There is a fine wire that goes from one metal end cap to the other. When too much current goes through the wire it melts. You can check this visually although an ohmmeter is better since sometime the wire melts right at the metal cap and it is hard to see.
A fuse can blow because of an external problem such as a shorted speaker or speaker wire. It can also blow because of a power surge or problem with the receiver itself.
