Hi! I got my Privia px-5S this afternoon and I was really excited to start recording it. First when I got the power on the LCD had text <ERROR> No Media. No sound could be played and nothing responded except power button. Few boots more and no change. So I started googling and found that upgrading the Firmwire had helped some who had had that No Media error. I downloaded the update file. Started to install and it seemed to go well but after few minutes lights started to flash and LCD was showing <ERROR> No Media then it changed to <ERROR> No File and the it says Initializing don´t touch. This was going in circles and after 10 minutes I understood that upgrade was never going to happen. I´ve done downloading with both Mac and Windows, used 2 different USB disks, tried booting with USB connected and with out... Remember I have not played a single note with the synth yet. I don´t know what firmware it was on. I just know that it doesn´t power up right. Any ideas?
