Re: on standby

Troubleshooting without a schematic. I found two 1 ohm resistors open in the positive 15 volt regulator circut. Located between associated power supply rectifiers and the 15 Volt Regulator. After checking for any short circuits I replaced the resistors. Ths restored operation of the unit. Owner thought the "Cable Guy" may have plugged something in wrong.

disconnect all connections and cycle power once again if you have the same results the amp has an internal problem and will need to be repaired. If the amp stays on start reconnecting and cycle power after you connect each device

Denon AVR-1601

This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop. You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149: 75f69d7.jpg These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors. You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes... Good luck and don't try this at home. Rob

If the resistor has been completely destroyed, look on the board for the circuit designation (eg. Rxxx). With that someone with the service manual or access to teh schematic can provide the value and wattage.
