The repair department repaired the GA-04 course translator board

❌ During fault detection, traces of overheating were found on the control and protection board with terminal blocks for external connections, in the form of a melted fuse block. 

✔️ The main electrical parameters have been checked. During further testing, a faulty microcontroller port was found, and a malfunction was also found in the power circuit of the P2 phase formation. Since the faulty port cannot be restored, the processor board with the course indicator and control buttons was replaced, the power circuit of the P2 phase formation was also repaired.
