We repair Perkin-Elmer Make HMI (PCB #0410293, ASSY #M0413322 REV C) which failed to display and had unstable operation. Testing showed IC faults, damaged capacitors, and power supply problems. These affected the smooth running of the HMI in its system. We repaired the circuits at micro-level and replaced faulty components. After repeated company-level testing, the HMI achieved reliable and consistent performance.
Note: We are not manufacturers, we only repair.
