More than likely the power supply has gone bad. I do not know if Denon uses a switch mode power supply or a linear supply. One way to tell is the weight of the amp. Heavy = linear supply and light = switch mode. Common problems with switch mode supplies are the FETs used for switch or the PWM generator (pulse width modulation generator) Linear supplies more than likely would have a bad bridge rectifier or shorted bypass cap on the DC rail.

We have a 2004 Venture. Ran fine yesterday. This morning absolutely no power. Battery and fuses check out fine. No wires look loose. Suggestions?


When you say the battery and fuses check out fine, do you have power at the fuses and the starter ? Do you have headlights ?

Did you pull the fuses and look at them? If you just stuck a probe in there you will get power even if the fuse is bad.

Generac NP 50G wont crank


Measure voltage drop across the far ends of the fuse wiring (should measure zero), as one of the wires or it's connection to either end of the fuse may be open. Check the battery negative grounding connection at the frame. If all ok, you may need to find a wiring diagram for the machine. Does this unit have a low-oil-level switch which will kill the engine if set?

Power windows do not work. fuse is fine


If all of the windows do not work and the fuse is fine, the problem is either the window switch on the drivers door or the wire is bad that provides power. Remove the door panel and meter the switch, if you get power to the switch but not through the switch the problem is the switch. If you are not getting power to the switch you know you have a wiring problem.

If the fuse is fine, check the hot wire leading to the lighter assembly to make sure you're getting power. If no, you've got a short in the wire from your fuse panel to lighter. If you are getting power to the lighter, take your test light and test the contacts on the inside of the lighter. If no power there, then replace lighter assembly. If you are getting power inside your lighter, it works fine, but the accessory you are plugging into it may be defective.

Check your main breaker fuse in your panel/subpanel.

Otherwise if the inline fuse is good and the main power is good, then look at the power supply for the microwave.
