Question about Audio Players & Recorders
It is going into protect mode. It is a common problem, but is not an easy problem to fix. It will go into protect for 3 main reasons. I work at an authorized Denon service center and have repaired many of these models, so I know what I am telling you is correct.
The receiver has a blown channel. This will require the replacement of many parts. The output transistors, supply resistors, driver transistors, and a capacitor in the driver circuit of the affected channel. It is usually the channel that is located closest to the display board on the main heat sink.
A bad voltage regulator in the power supply. It has several voltage regulators all on their own small heat sinks. It is usually ref # IC101 or ref # IC102.
IC101 is a positive 15 volt regulator and IC102 is a negative 15 volt regulator. More often than not, it is the negative regulator that has gone bad.
The amplifier circuit has a 10 ohm resistor that supplies a high voltage to it and that resistor opens up and must be replaced. It is ref # R184. It is a 10 ohm 1 watt resistor.
Those are the 3 main reasons for your problem. It is not an easy unit to fix, but it is well worth the cost of a repair considering how much these receivers cost to purchase a new one. If you do not have the proper tools to fix this unit, please do yourself a favor and have a service center fix it for you. You will need a multimeter, soldering iron, solder, solder wick, and a # 2 phillips screwdriver. You will also need to isolate whcih of these 3 problems is causing the unit to go into protect. If you have a multimeter I can help you with it, but you still need the soldering equipment and must be skilled at using it.
Let me know if you require more help,
