power supply pin-out voltages

Hi @frankkapiniaris

Usually electronic devices work on a maximum of +/-10% tolerance range with the voltage supply e.g. for 12V this is 10.8V-13.2V, so at 11V it's at the low end of the tolerance range which may be problematic.

Perhaps check if the electrolytic capacitors on the control board appear OK i.e. not domed or leaking. Also remove the CR2032 coin cell battery from the board and check its voltage as well. If it is <2.4V DC replace it.

Here's the ifixit D-Link DNS-323 Teardown guide that may help.

Hi @frankkapiniaris

The capacitance and voltage values are marked on each capacitor.

Take a picture of the board and then remove the faulty capacitors, one at a time, to read the value printed on the side of the capacitor.

Then mark the picture showing which one you removed and its value.

That way you know where the replacement should go and more importantly how it is connected on the board.

Electrolytic capacitors are polarity dependent so if you reverse them when reinstalling they will fail, sometimes spectacularly.

The grey strip down the side of the capacitor indicates the -ve (negative) leg whereas the board will show where the +ve (positive) leg is terminated. Usually there's a + symbol on the board next to where the +ve capacitor leg goes through the hole in the board to be soldered on the other side
