So I have been all excited about buying a Kurzweil PC3 LE7 for ~$1000. It arrived today nicely packed etc. I bought it from a seller with 100's of transactions and a 100% rating. The seller also offers a 14 day return guarantee so I'm covered.

I turned it on and all the buttons came up blinking with a lighted but blank LCD. On the 4th attempt it loaded the presets and it worked for 10 seconds and then went blank.

Funny thing- I have bought many used keyboards on Ebay & the local music store and never had a problem with anything. I am a gadjet geek & have found the electronics in general to be very reliable.

And since-say-sice approximately 1988 I have never had any device that has a CPU and needs to boot to have this specific problem.

Therefore, I find it vexing that this is my specific problem. Believe me-I am well aware that things break. I just don't want my toys to break.

And I am not crazy about Korean electronics; may be now I know why the reason for that. And I can't do a master reset because I don't have a system to reset. May be a firmware USB reset if the firmware has a bootloader? Any ideas? Other than return this beast? Thanks
