Q1a sound decoder problem -P2K GpP9i

Alex Stanojevic


One of my P2K locos with QSI Q1a sound decoder is failing in operation.

The sound gets distorted as soon as system is powered up. When the metal chassis is touched distortion amplifies.

After a while being powered locomotive loses address and it does not react to increasing speed steps.

It appears that the file inside flash RAM is corrupt. My NCE reports short circuit.

Does QSI have replacement boards for P2K models. Would Kelly Dorf be able to repair my QSI board?

Any help would be greatly appreciated.
