I think somthing may have blown on my technics sa-eh780 tuner as the sound quality is bad so I opend the unit & found that the fan isn't working & wondered what might have happend to it if its been overheating
I'm no expert but I think I'm right in saying that the fan doesn't kick in untill the volume is cranked up to a certain volume level because mine never does !
