BR900-CD schematic or service notes wanted

Post by domu »

I have dead BR900-CD which does not power properly - hang on boot.
Second week and no go. Without a schematic my chances to fix it are
close to zero.

I do have schematics of other Roland digital recording studios, but they
are completly different.

Anyone please?

Hi, I have a BR900CD and the screen is fine when track is zero'd and reading 1.001.001 etc.- as soon as I increase song position beyond that it dims. I think it might be power related in so much that at zero'd position the screen is getting 6v, when displaying poorly this drops to 4.8v. Did you ever get a schematic? Do you have one for the BR-864 or BR-800? (864 has same screen as 900, I also have a faulty 800 that screeches with nothing plugged into it (through both headphones out and line outs).

Any help appreciated.

Thank you.
