Question about Audio Players & Recorders
SOURCE: DNX7120 issue with VOL increase
I had the same issue. You can use the on screen volume buttons on screen to stop issue and don't use the physical buttons anymore. Watch out about a month after the volume problem started all physical buttons on my DXN7120 stopped working. There are a few reports of this online, I have not found a fix yet.

Since the buttons are fine it is definitely a problem with the main board(digital main). The problem is associated with logic control circuitry malfunction which is causing it to send commands to the microprocessor at will. The part is a large board, which is located near the board with all the inputs and has lots of ICs including the microprocessor. I have found a part but just make sure that the part number(934C265001) matches with the one in your set(the number will be printed on the board) before you order. It costs 357$ but they will return you 208$ if you ship them you faulty board, which works out to 148$
