This is a repair video for my MRC Prodigy Advanced Squared unit. The link function light was not working. I had power to the track but could not get a single locomotive to work and it was not sending a signal. I needed to replace an IC chip which I show in this video. Also, while repairing, I checked the other chips and contacts for wear and breakage. Hopefully this will help others out that may have had this issue.

Cause: The ethernet cord connectors were reversed on one of the new cables that I had used. I didn't check the cables before installing them. Lesson learned.

Part number for repair : SN75176BP DIP-8 IC
