Video: JVC X’Eye TMSS Hang Repair

Originally published on YouTube on October 10, 2019

This JVC X’Eye had an issue where it would hang on a black screen after displaying the power on “Produced or Licensed By Sega” prompt. I cover diagnosing the issue using a logic analyzer, then swap the faulty component (the Z80 sound processor) for a new one.

Shout out to Console5 for their excellent parts and the Wiki where they host schematics and service manuals.
