Hello. I have a Roland Fantom FA. which I bought last fall. Since about a week it is giving me a problem: About 3 times out of 10, when I turn it on the Display will not come on at all. Even if I turn it off and on again it still won't come on. And the next time it's fine again. Even when the display doesn't come on the sounds still work.
Is this a known problem? Is it very expensive to fix?
Thanks.
