Greetings!

That boot log looks fine. At this stage, I think you might have a bad VFD or a bad fuse on the main board going to the display board. If you have any of the remote access software loaded on your PC (Empeg Face for example, and I think emplode will also let you play tracks), you might be able to remotely control the player through the serial port.

Can you find the player with emplode?

Do you have the audio outputs hooked up to an amp or speakers? This will verify the audio circuitry.
