Hi there,
I just hooked up my SliMP3 to a lab power supply and stepped down the voltage from 5V. Guess what, below ~4.6V audio drops out but otherwise the device works (receives IR commands, display working properly, shows playing progress, etc.). So it seems the DAC is the first to quit when the input voltage gets too low whereas the rest of the device keeps working. Stepping the voltage back up leads to heavy distortions first until it recovers at ~4.65V. And it takes just 0.45A at this voltage so its power consumption is only a bit more than 2.1 Watts which I find pretty amazing. It is typical for switching power supplies that they fail to keep up the specified voltage sooner or later, depending on the load. Mostly this is due to dying filter capacitors in the secondary stage of the power supply. This does not happen all at once but is a slow but steady process so the effective voltage delivered will ramp down very slowly over time. Yours might just be in a state where the voltage is sufficient for everything except the DAC. So the PSU - once again - would by my prime suspect here. They are dirt cheap (unless you want something really well-made) so I would recommend to replace it. It's very likely this brings your SliMP3 back to full glory. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!
