Servo Shock Tester Repair Needed on site. Only for Indians

My Amar Engineers & Fabricators servo-hydraulic shock-absorber testing machine has stopped reaching its Home position. When I give the Home command it stays put—there’s no movement at all—yet the power-pack motor starts and the gauge shows normal pressure. No obvious oil leaks, noise, vibration, or overheating are present; the electronics (LVDT, software, interface) have already been verified. I now need an experienced freelance service engineer to come to site in Karnataka for a full mechanical-hydraulic investigation and repair. Key tasks will include inspecting and, if required, overhauling the hydraulic cylinder, checking the servo valve and power-pack, verifying alignment, bushes, bearings, and the piston rod, and eliminating whatever is preventing the system from finding its stroke reference. Please reply with examples of similar servo-hydraulic maintenance you have handled, your earliest on-site availability, contact number, and your service rate structure. I am ready to schedule the visit as soon as I review your credentials and estimate.
