Ronald is apparently utilizing the restore method, rather than the replace parts method.
For the radio, sure, I could fix the display on the unit in it, or, I could install the spare I have. One method requires the time to remove and re-install, and the other requires that time, plus time to disassemble, test, re-assemble (probably several times), plus some parts, tools, and oil. It isnxt worth the hour or so extra of my time.
