Portastudio 2488
Got a portastudio a friend wants me to look at for them. Has a SDRam error 4, not much info googling it but the couple of posts I found suggest repair centres say to just scrap it and put in a new/refurb board.

I was wondering if anyone on here had successfully repaired this fault, I am assuming it's down to a failing ram chip, I am quite capable of replacing it, but with it being an intermittent fault. Is it a particular chip or cap that causes the issue or is it worth just replacing all the ram chips in one go?
