The Rise of the TV370B in Case Construction’s Lineup
Case Construction Equipment, a division of CNH Industrial, has been producing compact track loaders for decades. The TV370B, introduced as part of the B Series, represents a modern evolution of Case’s mid-frame CTLs. Designed for versatility, the TV370B combines a 74-horsepower engine with a 3,700-pound rated operating capacity, making it suitable for grading, lifting, and material handling across construction, landscaping, and agricultural sectors.
The B Series introduced enhanced operator interfaces, including a 8-inch LCD multi-function display, improved electro-hydraulic controls, and telematics integration. These upgrades aimed to streamline diagnostics, increase operator comfort, and reduce downtime. Since its release, the TV370B has seen strong adoption in North America and parts of Europe, with thousands of units deployed across job sites.
Understanding the Screen Boot Failure
One of the more frustrating issues reported by operators is the failure of the LCD screen to load beyond the initial Case logo. In such cases, the machine powers on, the logo appears, but the password prompt or main interface never loads. This renders the loader inoperable, as key functions like hydraulic control, diagnostics, and machine settings are locked behind the screen interface.
This issue is typically rooted in one of the following causes:
Operators encountering this issue can follow a structured diagnostic path:
Preventive Measures and Design Considerations
To reduce the likelihood of screen failures:
Broader Electrical Challenges in the TV370B
Beyond screen issues, the TV370B has faced occasional electrical anomalies:
Recommendations for Owners and Technicians
In 2023, a landscaping company in Georgia experienced a screen failure on their TV370B during peak season. With no dealership nearby, the owner contacted a retired Case technician who guided them through a manual reset using a battery disconnect and harness inspection. The machine was back in service within two hours, saving the company from costly delays.
Conclusion
Screen problems in the Case TV370B are more than a nuisance—they can halt operations and complicate diagnostics. As compact track loaders become increasingly reliant on digital interfaces, understanding the root causes and preventive strategies becomes essential. With proper care, informed troubleshooting, and proactive maintenance, operators can keep their machines running smoothly and avoid the pitfalls of electronic downtime.

In such cases, the machine powers on, the logo appears, but the password prompt or main interface never loads. This renders the loader inoperable, as key functions like hydraulic control, diagnostics, and machine settings are locked behind the screen interface.
This issue is typically rooted in one of the following causes:
- Faulty display controller board
- Corrupted firmware or software
- Voltage irregularities during startup
- Moisture intrusion or condensation behind the screen
- Loose harness connections or damaged pins
- LCD Multi-Function Display: A digital screen that provides access to machine diagnostics, settings, and operational data.
- Firmware: Embedded software that controls hardware functions; stored in non-volatile memory.
- CAN Bus: Controller Area Network system used for communication between electronic components in heavy machinery.
- Boot Loop: A condition where a device repeatedly attempts to start but fails to reach full operational state.
Operators encountering this issue can follow a structured diagnostic path:
- Disconnect the battery for 10 minutes to reset the system
- Inspect the wiring harness behind the display for corrosion or loose connections
- Check voltage at the display input; should be stable between 12–14V
- Attempt a firmware reload using a dealer diagnostic tool
- Replace the display unit if internal damage is suspected
Preventive Measures and Design Considerations
To reduce the likelihood of screen failures:
- Ensure the cab remains sealed during wet weather
- Avoid power cycling the machine rapidly
- Use surge-protected battery systems in high-voltage environments
- Schedule periodic inspections of electronic connectors
Broader Electrical Challenges in the TV370B
Beyond screen issues, the TV370B has faced occasional electrical anomalies:
- Joystick sensitivity fluctuations due to software calibration drift
- Intermittent sensor faults in the emissions system
- CAN Bus communication errors during cold starts
Recommendations for Owners and Technicians
- Keep a log of screen behavior and startup anomalies
- Request firmware updates during routine service visits
- Use dielectric grease on connectors to prevent corrosion
- Train operators to recognize early signs of electrical failure
- Consider extended warranty coverage for electronic components
