The flashing light sounds like an error code.
What does the manual say?

Thanks lewis bros,
it's not mentioned in the regular manual, maybe a service manual , but I don't have access to one. I was thinking the same thing about the service code, but I hate to fork out the bucks if it's something i can do myself

i can tell you with all certainty it is a power supply failure..

i had one do that and never found out what the hell it was.

but then i had my father fix it.... he knows his way around a circuit board. i know alesis said they don't sell "just" the power supply, so he got it from somewhere else... i'll ask him first chance i get and see if you cant get one too..

its only like $60 if i remember (don't quote me) and super easy to install

i'll repost when i know for sure

Hello! I had the same problem but solved it alone by replacing a couple of components in the circuit board!
Quick and cheap fix! I made a short instruction on how to do it aswell. Hope it helps :)

Yes, very good. I hope the original poster is still around (13 years later)!
