In the latest video from Reviving Retro, the host tackles a newly acquired Commodore SX-64, which reportedly has a blank screen issue. Upon powering it on, they discover more than just a blank display—the drive LED remains illuminated, and the drive itself doesn’t stop spinning. This suggests multiple issues, including a display problem, likely due to a faulty PLA chip, and a more complex drive malfunction.
The host dives in with a systematic approach, leveraging an arsenal of repair techniques to address both issues. Starting with the screen problem, they plan to move on to the drive’s troubles afterward. Potential fixes include inspecting components like the 7406 logic chip and the drive ROM. Watch as they open up the machine and begin troubleshooting each problem to bring the SX-64 back to life.
