A Pyramid PS21KX radio may not work after sparking, even if the fuses are okay and the power supply is functioning, due to potential internal component damage. The spark could have caused failure in key electronic components such as diodes, transistors, voltage regulators, or circuit board traces. Additionally, connections or solder joints may have been damaged, preventing proper operation. Checking for visible burn marks, damaged components, or broken connections inside the radio could help diagnose the issue.
