Diagnosing video signal loss on Wii and GBS-Control

Last year, I bought a GBS-Control to upscale game consoles for a VGA CRT monitor, but started having issues with random black screens while playing my Wii in 480p. What seemed like a simple software problem led to a months-long adventure involving overheating chips, RF interference, and debugging the GBS-Control firmware. Surprisingly, the root cause was traced back to a malfunctioning Wii and a dimmer light switch radiating RF energy. Replacing the switch resolved the sync loss issues, leading to uninterrupted gameplay. The journey showcased the author’s innovative problem-solving skills and diligence in tackling complex technical challenges.
