No sound at all, but power on. Should I replace the phone jack?
Hi Hermann ,
This is a typical issue with Logitech speakers . You need to bring them back to the the dealer and get an exchange set for free replacement onder warranty . If the warranty has expired , you will need to solve the problem by testing the cables or the printcircuit inside the sub , BUT first connect your head phones or another speakers set to the correct output of your computer's soundcard to verify if the issue actually commes from the speakers . If the test is negative , the issue is to be found in the soundcard and you will need to replace it .
Best regards .
