Hello expert, My Klipsch Pro Media V2.1 from older generation with (Fuse). The sound was fantastic until recently when I on the power and strong green light turned on but it will last about 1.5- 2 hours the green light starting to faded and guess what eventually the light goes off... but still I can hear the sound. If I increase my laptop volume, the sound can't be loud and not clear. May I know what is going on? I really love this speaker set and even my family love it.. because the sound is crips and warm... really good sound system. I haven't open and check the amps because I hope I can find some answer before I started. TQ
