1. Direct Cost Comparison (Single Display)
| Cost Item | CRT Repair | LCD Retrofit |
|---|---|---|
| Parts cost | CNY 500-1,500 (varies by failure type) | CNY 800-3,500 (one-time) |
| Labor cost | CNY 300-800 per repair | CNY 200-500 (one-time installation) |
| Downtime cost | CNY 1,000-5,000 per incident (unplanned) | CNY 0 (scheduled maintenance) |
| Shipping/logistics | CNY 100-300 per repair | CNY 100-300 (one-time) |
| First-year total | CNY 1,900-7,600 | CNY 1,100-4,300 |
2. 5-Year Total Cost of Ownership
| Year | CRT Repair Cumulative | LCD Retrofit Cumulative | Savings with LCD |
|---|---|---|---|
| Year 1 | CNY 3,800 | CNY 2,500 | CNY 1,300 |
| Year 2 | CNY 7,600 | CNY 2,500 | CNY 5,100 |
| Year 3 | CNY 11,400 | CNY 2,500 | CNY 8,900 |
| Year 4 | CNY 15,200 | CNY 2,500 | CNY 12,700 |
| Year 5 | CNY 19,000 | CNY 2,500 | CNY 16,500 |
Note: CRT repair costs assume 2 incidents per year at average cost. Actual CRT failure rate typically increases with age.
3. Hidden Costs of CRT Repair
- Production loss: Each unplanned CRT failure causes 2-8 hours of production downtime
- Inventory risk: CRT tubes are increasingly scarce; lead times of 2-4 weeks for replacement tubes
- Repeat failures: Repaired CRTs have a 40-60% failure recurrence rate within 12 months
- Safety risk: CRT high-voltage circuits (25kV+) pose electrical hazard during repair
- Environmental compliance: CRT disposal requires special handling for lead and phosphor waste
4. LCD Retrofit Benefits Beyond Cost Savings
| Benefit | Quantitative Impact |
|---|---|
| Power consumption reduction | 73% less (30W → 8W per display) |
| MTBF improvement | 4x longer (20,000h → 80,000h) |
| Maintenance elimination | Zero display-related service calls for 5+ years |
| Operator comfort | Flicker-free display reduces eye strain |
| Environmental compliance | , no hazardous materials |
5. Recommendation
For FANUC CNC systems with CRT displays older than 8 years, LCD retrofit is the clear economic choice. The investment pays for itself within 12-18 months, and the long-term savings are substantial.

9. Frequently Asked Questions
Q: Can I replace my CRT with an LCD myself?
A: Yes. Our LCD modules are designed for straightforward DIY installation. If your current CRT is working (even if dim or flickering), you can unplug it and plug in our LCD module in about 10 minutes.
Q: Will an LCD last longer than a repaired CRT?
A: Significantly. LCD lifespan is 50,000+ hours (15+ years at 8 hours/day). A repaired CRT typically lasts 6-24 months before the next failure.
Q: Do you offer volume discounts for multiple monitors?
A: Yes. Contact us at [email protected] or via our quote form for volume pricing on 5+ units.
