It's unlikely that the missing capacitor would cause a no-boot fault that occurs 100% of the time. These capacitors are designed to provide a path to ground for the switching noise coming from the adjacent logic chips. This is good design, but very often not strictly necessary; I would expect your system to still boot somewhere between often and occasionally with this cap missing.
What else have you done to troubleshoot the system? -Josh On Fri, Oct 22, 2021 at 12:02 PM ExPLIT | Pawel Radomychelski <exp...@mailbox.org> wrote: > > Thanks Steve, > Tried cliping it out - same issue.
