MC-909 - freezes on start screen
Posted: 18:26, 4 September 2013
Hi there,
I have opportunity to buy very very cheap mc-909 from someone. It's not functional - freezes on start screen with Roland logo.
Do You know what might it be?
I'm not a big engineer, but i've asked few people and they think it's because one of the flash rom chips, and it should be replaced
I'd like to risk. I don't have roland service in my country and even if i had- i can't afford it.
I've found some electronic shops with toshiba and fujitsu chips for few dollars. Let's suppose I've made it and soldered chips. Do i need to program sth on them? Where is firmware of mc909 installed? Generally - what do You think about it?
