My Denon AVR-1802 is permanently stuck in tone defeat. The display actually shows that the tone defeat can be turned off and on, but the tone controls, ie. bass and treble do not alter the sound in any way, even when the Tone Defeat is not activated.

you can not do this. this option is no available.

Reference to the manuals is highly recommended. All controls and indicators are explained. There may actually be a clue on the front panel. Resetting the microprocessor is a last gasp solution and may only bury you deeper because it will zero out all settings.

You could try a total reset of the system. To do so, Press Power while simultaneously pressing Speaker A and Speaker B. When the display flashes at about 1 sec intervals, release all buttons. Then select a desired source as normal and see if it plays as expected.

replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

no, you can't

connect your analog output from the cablebox to the receiver md/tape in. then connect your tv audio input to the md/tape out of the receiver. or you could just pass it straight from the box to the tv, bypassing the receiver altogether.

I hate to be the bearer f bad news but it has been my experience , anything hit by lightening stays hit permanantly ..
You may find a few components on the quick scan of the circuit burnt or damaged , but you can guarantee that other components have been fried also .. It does enough damage to any electrical system when you get a 300v spike on the mains .. so imagine what approx 1/2 a million volts will do to a 12 volt radio ?? dont waste your money call your insuarnce company and claim for it ?. ...

Hi,
I have same DD 5.1 tiny "bursts" problem with satellite HD channel. It is probably problem with Crystal DSP (German site): http://forum.digitalfernsehen.de/forum/showthread.php?t=89328&page=3
"Denon bietet Lösung für EX-Flag-Problem bei den Modellen AVR-1602 und AVR-1802 an

07.08.2002(cr)
Dass die Denon AV-Receiver AVR-1802 und AVR-1602 die mit einem DD 5.1EX-Flag versehenen Tonspur von "Atlantis" und dem "Herrn der Ringe"nicht abspielen können, ist ein spezifisches Problem von einerbestimmten Revision des in diesen Geräten verbauten Crystal DSPs.Dieser Chip wird u.a auch in einigen Kenwood- und Onkyo-Modelleneingesetzt.Da es von diesem Crystal Chip unterschiedliche verbauteRevisionen gibt, von denen aber nur eine bestimmte betroffen ist,werden die beiden Filme auf dem größten Teil der verkauften AV-Receiverohne Schwierigkeiten laufen.
Denon bietet nun für alle betroffenen Kunden, die ihr Gerät beimdeutschen autorisierten Fachhandel erworben haben, eine kostenloseModifikation an. Das Gerät muss beim entsprechenden Fachhändlerabgegeben werden mit dem Hinweis auf das Herr-der-Ringe- bzw.Atlantis-Problem.
Momentan steht nur eine begrenzte Anzahl an DSPs zur Verfügung - Denonhofft, dass kurzfristig ein größeres Kontingent eintrifft.
Denon bittet daher die Kunden freundlich um Verständnis, dass nichtalle betroffenen Geräte auf einmal und sofort umgerüstet werden können."

Many original remotes are exspensive and hard to get hold of , Radio Shack or Maplins have many universal remotes that not only will allow you to control your AVR 1802 but many other devices you have also ... at probably half the price . ... regards Vortash
