KLH KL2400 a/v receiver

[Sigmakay]

I have a KLH KL2400 stereo a/v receiver that powers up but has no sound.
It was working fine yesterday, but today no sound. All the controls seem
to work just no sound. Any help would be appreciated.

I am still waiting for somebody to at least tell me that they don't know anything about klh equipment. All I asked for was some input.

Are the pre-in/pre-out jumpers installed correctly on the back? The pins should be seated at left to left, and right to right. Even if they are correctly placed, pull them and firmly reseat them. Might be good to spray some contact cleaner in those jacks (if you have some) before doing so.

Did you accidentally disengage the speakers or engage the tape monitor function?

Just a few suggestions to check. Beyond that, I've got nothing.

Blown speaker protection fuses maybe?
