Tims Retro Corner | Amiga CD32 Restoration Part 2: Replace and calibrate the laser. Rectifying Mistakes. @TimsRetroCorner | Uploaded January 2024 | Updated October 2024, 2 hours ago.
Thanks to pcbway.com Great PCBs from $5. In part 2 of my CD32 restoration, I fit and calibrate a new laser assembly, replace the two bulging capacitors that I fitted backwards last time, and investigate the left audio channel producing no sound.
Instructions for calibrating the laser came from Mike's Vintage Tech, check out his video here: youtube.com/watch?v=chIF8JrIFS4
and from the TSB blog, check that out here: https://www.tsb.space/knowledge-base/amiga-cd32-laser-calibration-replace-laser-pickup-procedure/
