I bought this B&K Precision 1550 power supply new back in February 2023 from a reputable and authorized distributor, used it a few times, and it worked great until recently. Now it always shows 0V and 0.16A Current Controlled (CC) no matter what I do with the controls. This is my first power supply as a hobbyist so I could be doing something wrong with it. AFAIK I've not abused it -- no shorts, no high temperatures, not dropped or hit, nothing spilled on it. Just one day I powered it on and it decided not to work. I checked the fuse and it's good. The USB port still provides 5.2V.
Should I send it in for repairs? What could cause such a problem? I'm a little confused how it could apparently fail(?) so early and so easily from such a reputable manufacturer. I bought it specifically because of the brand and because it's what I could afford.
The first pic shows the output, the second has me setting the current limit, and the third shows me setting the voltage, all with no load.
