I have a Marantz ST100. Speakers not playing after making a loud POP sound.
I have a Marantz ST100. I havent played in in a couple of years I went to listen to it and I turned on receiver and radio was playing through speakers. I turned on CD and hit CD input button on receiver and a loud POP came through the speakers and now I have no sound. Everything is powering up but no sound from speakers at all. I wonder what happened? Thanks so much.

It could be a burned out resistor in the main power amp. Follow the channel wires from the speaker that is playing up till you get to the power amp. Look around for anything odd. Compare it with the other channels, as they are good.
May be a fuse inside blown , if it makes a loud pop that can take out a fuse, If you find one blown , replace with same type and try machine .Dont replace with higher rated fuse though , if it keeps blowing. Try using headphones and if you get sound , may be speakers. pete
It's probably not heat due to the Marantz' large frame and heat-synchs.
This could simply be a mismatch of impedance. The amp is 120w per channel, so make sure the speakers can handle this. Check the impedance (ohms) of the speakers and the amp as well.
Clipping can be caused by overpowering the speakers, which could damage the speakers in the long-run.
If this is only from 1 source- (i.e.- Blu-ray player or cable) then it could be digital clipping.. This Marantz can decode 96kHz PCM or normal Dolby Digital & DTS. If this is a Blu-ray it may be streaming 192kHz PCM... (but most likely the Marantz will not even attempt to play that audio)
I hope this helps.
Sounds like a loose connection or a blown speaker. I would try just playing around with the wires to see if you can make it pop, if so, the wire you were messing with is the most likely culprit. Also, verify the sub cone has no damage or cracks. I am betting it i a bad connection or a loose wire.
I have a sansui 19" LCD TV+DVD I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there. The set is not yet 2 years old.
