My NS-LCD26A television has been working fine for the past year, and then all of a sudden the sound went out. I thought it might be my cable, so I tried the DVD player too, still no luck. I've checked all my connections, tried connecting with different types of cables, and tried cleaning the connections... still no sound (picture is fine). Does anyone have any idea what's causing this and how much it'll cost to fix it? I don't have a service plan because I won it in a raffle. Please help!
