Okay, I'm back with some updates: The keyboard is up-to-date with the latest firmware version (1.13). The power supply is not the issue, because I get the same problem with batteries installed and the power supply unplugged. The problem can be fixed (temporarily?) by unplugging either the USB cable, the sustain pedal, or both from the back of the unit before powering it on. I did this yesterday, and now the unit seems to power on properly, even with the pedal and USB plugged back in. However... Now the sustain pedal input does not work. I checked in my DAW, and input #2 (half-pedaling/damper) still sends MIDI messages, but input #1 (conventional sustain) does not. This means it's not the pedal, but the jack or some internal connection.I sent a description of my problem to the people I bought it from at Sweetwater and they said they'd take a look at it if I sent it in. I will probably ship it to them over the weekend or next week, just to see if I can get any input here first. My current hypothesis is that there may be internal damage to the back of the unit, which would explain why there seems to be some relation between the power problems and the pedal problems.

Hi all, I wonder if anyone has experienced the issue I'm having. I tried to search for it but nothing came up (which worries me)... basically, whenever I power up the PX-5S, it shuts down immediately after it's finished booting up. I get the "piano", "elec piano," "organ" lights turning on in sequence, and the screen says "Please Wait", and then as soon as it's done, everything goes black. Usually rebooting a few times seems to help, but today I have tried doing that about 20 times and it won't stay on. What can I do?
