My screen does not show anything everything works fine.I replaced screen but no luck.thanks

I would like to know a little bit more about your problem before I try and troubleshoot it...it sounds like you may have a bad connection to your screen and it needs to be looked at by an electrician that you trust. I have a roland U-220 Module that has died on me twice within the last 10 days and I find myself trying to reload it but, it keeps dropping it's ram. I know that I had this problem fixed one time before and I am going to have to send it to the guy who has worked on it before to see if it is even worth trying to salvage or if I should bite the bullet and save the cash to upgrade to something a little more updated. I hate the fact that I lost such a great piece of equipment, but they will all eventually break down.
