Hello I need firmware for denon 1740 Dvd. Cant not
Go to the Denon Global Website and select Europe, once on the Europe site go to downloads the 1740 will show up in the model drop down menu. You'll need the unit Serial Number, good luck on that, I couldn't find one anywhere on my unit.
Next step? Buy a Sony.
Denon 687 ,,,,red light is on then I push the power button and it blinks green and their stays green but no display at all nothing else lights up
Considering you have a standby light we know the hot side of the power board is working, next step is test the power on signal coming from the main board, it should be marked on the legend on the power board what pin is power on, will be marked PO_ ON PWR or something like that, you need at least 3 vdc there when you turn the set on, if it's missing replace the main board, if you see voltage replace the power board, easy simple fix with only one measurement, verses guessing what board is bad. Sorry you didn't get any other useful help, there are some posters on here giving non helpful generic help anyone would know to try
Completely clueless on setting up Denon 1709 AVR
Yes, you can still use the speakers even if they are not currently connected to a TV. To connect the speakers to your computer, you will need an audio cable with 3.5mm plugs on both ends. One end will plug into the headphone jack on your computer, and the other end will plug into the input on the speakers. Some speakers may also have RCA input, in which case you will need an RCA-to-3.5mm audio cable.
If you have a newer computer with only a digital output (such as a USB-C port), you may need to use an audio interface or a digital-to-analog converter (DAC) to convert the digital signal to analog so you can plug it into your speakers.
Once the speakers are connected to your computer, you can adjust the volume using the volume controls on your computer or the speakers themselves. It's important to note that your TV will not be able to use the speakers unless they are connected to it.
