Hey Birt! | Vintage LCD x3 – Let’s try to repair 3 different TRS-80 Model 100 LCD panels @HeyBirt | Uploaded June 2022 | Updated October 2024, 3 hours ago.
Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.com
In this video we take a look at three different TRS-80 Model 100 LCD screens, each of which has a different problem. We’ll learn how to test the LCD driver chips, interpret the waveforms they put out and see how many of the screens can be fixed.
How many can we get working properly again? Perhaps one or two or maybe even all three? Join us and find out.
