I couldn't find any way to backlight my Roland TR-505, though, so if anyone has any ideas, just let me know.įloppy drives tend to be easier to replace, but there are sometimes complications.
Here's a link to a pretty detailed description from a blog post describing the process for a Korg Wavestation: . Some synthesizer expander modules (the Yamaha TX7, for example) are very easy, whilst some keyboard workstations can require quite extensive amounts of disassembly. When you start replacing displays, you quickly discover that the difficulty of doing it varies enormously. To be more accurate, I mean 'what used to be backlit' displays. I've been gradually replacing the backlit displays and floppy drives on my vintage gear. It seems that old drive belts go loose, or go sticky, or go brittle, and all of these tend to result in a floppy drive that doesn't work. If you can find OLED replacements then these are arguably the best, but I haven't been able to find out much about the real-world long-term life of them - after all, 90s gear is nearly 30 years old! And then there are 3.5 inch floppy disk drives - particularly the ones which use belts instead of direct drive. Unsoldering capacitors is fiddly work, really needs a good quality desoldering station, and can take a lot of time if there are lots of capacitors to change (replace with higher temperature rating and higher voltage if there is space.) Backlit LCD displays are another common problem, where the electroluminescent backlight drivers fail over time, and the LED backlights gradually seem to go dim.
There is already a lot of material available online about replacing electrolytic capacitors, which heat and age can dry out causing them to lose capacitance.
Vintage gear can develop a number of problems.
