About 2 months ago the front display on mine just quit. I couldn't figure it out. Well...a month later I turned it on...and I only clicked once (it usually clicks twice) and no sound. So I called around and got some estimates...$75 to $125 an Hour. Plus parts. Well...I was reading a Smarthome for Dummies book last night. Well.... I Think I Fried It! I was reading about Impedance. Uh Oh! I had 2 speakers wired through one terminal. I think it overheated. I took it apart just kinda poking around. I took off the front panel and The plastic behind the display was melted! Now...It this a fixable problem or should I buy a new receiver?
