Question about Denon AVR-1803 Receiver
Recently, after 3+ years of ownership, my Denon AVR-1803 shuts down after about 10-20 minutes of viewing a DVD. I can power it back up, then it usually shuts down again, usually after about 10 more minutes, but sometimes longer. What's going on here? Why is it doing that? It has plenty of ventilation/air circulation, is not exposed to sunlight, and is not played at loud levels.
Also, when viewing some DVD's, even newly released ones, it choses "stereo dvd" or "Dolby D" instead of letting me chose other options like PLII. What's the reason for that?
Thanks for your anticipated response.
I am a Tech in Michigan and have worked on lots and Lots of Denon AV Receivers. These units have Protection circuits for Overcurrent, Dc Protect, 15v Regulator inbalance, Rail Voltage Inbalance, Low Ac Voltage, Low Standby Voltage and Thermal Protection just to name the ones I remember. My guess is you Probably have either Poor Intermittent solder connections or Amp is not Ventillating Properly. Make sure you leave room above Receiver to Vent and You are using no Less then 6 ohm speaker Impedance per ch. Refer to Speaker Impedance chart on back panel . firstname.lastname@example.org

My receiver will sometimes quit having surround sound in the TV mode. The guy I bought it from usually gives me an easy sequence to follow to turn it back on, but he has left town. Thanks

The reciever has built in overvoltage and overcurrent sensing, its similar to the lm78 monitering chip you find on many pcmotherboards, unfortunately it could be the chip itself causing the problem or one of the other symptoms is causing the reciever to shut down. check all cabling, check your electrical power source. I.E. ,I just had a weird problem with my PC 0ne of the cooling fans was drawing to much current and it was causing intermittent symptoms.
