Audio from both the coax and optical inputs cuts out after a few minutes. The audio from the coax cuts after 1-2 minutes while the audio from the optical cuts out after 5-10 minutes - this occurs on all four of the digital inputs. All the analog audio inputs operate fine. The fan does not ever seem to turn on either - but I have refrained from leaving the receiver on for extended periods of time.
I bought this unit refurbished around 6 years ago and quit using it a years ago when this problem occurred - my main concern is that the repair cost would equal that of a new comparable unit.

Re: sound from digital input(s cut out
You are probably correct. The input switcher IC or the power supply feeding the Optical switcher is most likly got a problem. The cost to diagnoise a problem like this could cost you with a repair, more then you could most likly get a new reciver for. Its a shame of all the great technology that gets thrown aweay in the dumps every day. Good Luck

1. cable box video out to video 1 in on the lcd , audio out to reciever input 1 ( tv, vcr , or what you want it on )
2. dvd s-video output to lcd video 2 s-video input , dvd audio out to reciever dvd/cd audio input , and add the optical or coax cable digital audio for dolby digital surround sound
you can use the headphone jack just get an adaptor to change from the headphone type to RCA type. adjust the volume of the tv to 3/4 of the way to give line level to the stereo, use an aux input on the stereo. if you had a suround sound dolby digital / DTS receiver then use the digital coax out to that type of receiver, but since you have an anolog 2 channel receiver you must use the only anolog source (the headphone).
