Over years of thermal cycles, the internal ceramic filters, inductors, and trimmers will drift. An alignment restores the radio to its factory-spec sensitivity and frequency accuracy.
Trace the voltage at the backlight power rails on the display PCB. If voltage is present but the LEDs do not illuminate, replace the SMD LEDs. Alignment and Calibration Procedures
However, like any sophisticated piece of analog-digital hybrid electronics, components age, alignments drift, and mechanical parts wear out. To keep this powerhouse operating at peak performance, a thorough understanding of the is essential.
