The Corona pandemic gives me reason to stay indoors and burn up some brain cells trying to fix a problem which seems to plague a lot of SAE CD Players. Often the digital display will lose segments or go completely dead. Unfortunately the display is not just an array of simple 7 segment LED's. It is a complex, self contained unit, that communicates serially with the main board. When it goes bad it is not repairable. The chip on it looks like a glob of epoxy. This assembly is unobtanium today.The SAE D102 is based on a Phillips/Magnavox chassis. The Phillips/Mag players tend to exhibit similar problems and use Green LEDs instead of Red. I was inspired when I saw that someone in the Netherlands had reverse engineered the display module for a Phillips unit. I actually tried to contact that person but my questions failed to get a response. I can understand when people don't want to share their hard work so I decided to reverse engineer the SAE display module on my own. The SAE variant is different. It has more pins (12 instead of 9 or 10) and addresses 34 display bits to not only update four 7-Segment LED's but also drive 5 other stand-alone LED's such as Pause, Error, Index, Time and Repeat. The device I am offering is a pin perfect replacement of the original display. Every display is tested with a custom testing jig. It is tested when produced and tested again just before shipment. A PDF with install tips will be sent to you as well. I can send this PDF to any individual who wants to review the scope of work required to install this!
