There is no need for a manual. It is so easy to operate because it is designed for easy opeating. If you need a manual to operate the PSR-510 then you really won't be able to operate it even after studying the manual. But here it is just in case you can by some miracle!

I would go and purchase a can of compressed air, open up the electornics, blow out the USB, quarter inch plug-in keys. Dust may have gotton into the system and needs to be removed. You didn't mention, do LED lights come on at any time?

The unit probably is detecting an error during the power on test... A long shot MIGHT be a button or key that is stuck on, that is sensed as being pressed. See if all the buttons are completly up. If the unit has a harddrive, a failure of it can block the booting even though the operating software is not on the drive in these. If you find a button that is sticking, put a tiney bit of CRC226 around it with a Q tip. You can get the CRC226 in the electrical dept of Home Depot. You just want to wipe the edges of the button to lube it a bit.

Yamaha prefers to MAKE the instruments rather than conducting repair schools... they may have some very specialized schools for individual types when first introduced. With the situation in Japan right now such classes would be cancelled I am sure. Instrument repair is so specialized other than basic piano repair/tuning that you will find few if any courses. For piano repair you might want to search YouTube for videos. For organs and keyboards, detailed electronic knowledge and the service manuals are what we have to work with. You need both experience in digital and analog plus test equipment including oscilloscopes and signal generators as a start.
