Tell me what it's doing. I'll tell you what it needs — and what it will take — before any work starts.
Every repair starts the same way: I look, I diagnose, and you get an honest answer — including "it's not worth fixing" when that's the truth. Nothing gets opened, replaced, or wiped without your OK.
Inspected open-box machines and gear from my shop — honest condition notes, and I'll move your files over.
