i have one KVM-121 that it doesn't work. when i connect the computer's cable to it sounds like tegh tegh tegh. the sound is from the relay on the board and i don't know what's the reason and i can't see anything on the board. i don't have it's schematic but i guess an alternative voltage of one element on the board cause this sound. but where and which element?
thanks every body
