So, I was bored and figured I'd replace the backlight sheet for an LCD screen in an old 90s sampler. (I'd ordered the replacement in 2023.)
Boy, that was annoying!
I had to completely detach the metal bracket that snuggly presses the LCD screen and 2 zebra strips to the PCB; so I can desolder the old and put the new one in.
With all PCBs bare, I had to turn on the machine, and adjust and move the LCD until the 4 rows of text actually made sense.
