Common Equipment Failures

Cracked or Dead Touchscreen
Digitizer replacement and glass repair for resistive and capacitive touch panels common on modern FENDT and JD terminals.
Backlight Failure
LED and CCFL backlight strip replacement for screens that are dim, flickering, or completely dark even though the display panel itself is still working.
Water & Moisture Damage
Cab seal failures let moisture into terminals. We clean, re-inspect, replace corroded connectors and damaged board sections.
Connector & Harness Faults
Broken Deutsch or proprietary connector pins, corroded CANBUS connectors, and damaged display harnesses. Particularly common on older FENDT series.
Controller Board Failure
Main PCB failures causing boot loops, black screens, or erratic behavior. We diagnose at the component level and repair rather than replace where we can.
Firmware & Software Issues
Corrupted firmware recovery, configuration backup and restore, and software fault diagnosis before recommending hardware replacement.
Power Supply Faults
Voltage regulator and DC-DC converter failures inside display units, causing intermittent shutdowns or failure to power on.
GPS & Antenna Issues
Integrated GPS module failures, antenna connector damage, and signal reception issues on combined guidance display units.
Gauge Failure
Speedometer, RPM, fuel, and hydraulic temperature gauges reading incorrectly or not responding. Failed stepper motors, sensor inputs, and cluster driver circuits repaired at the component level.
LCD Segment Issues
Dead or dim segments on digital readouts, bar-graph fuel gauges, and hour meter displays inside the tractor cluster panel.
Backlight Failure
Failed or dim instrument panel illumination making gauges unreadable at night or in dusty cab conditions. LED and EL backlight elements replaced without swapping the full cluster.
Warning Light Faults
PTO engagement, hydraulic pressure, engine load, and other warning indicators stuck on or failing to illuminate when required on tractor clusters.
CAN Bus Fault
Tractor cluster not receiving data from the ECU or CAN bus, causing blank or frozen gauge readings. Fault diagnosed to the module, wiring, or bus termination before any parts are replaced.
Hour Meter Data Loss
Lost or incorrect engine hour readings after a power event or battery disconnect. Stored EEPROM data recovered where possible and root cause identified to prevent recurrence.
Connector Corrosion
Corroded connector pins on cluster harness plugs causing intermittent gauge dropouts or full cluster failure. Common on tractors regularly pressure-washed or exposed to field moisture.
Housing & Lens Damage
Cracked or fogged cluster lenses and damaged housings allowing condensation inside the panel. Lenses sourced and housings repaired to restore a clear, sealed instrument face.
Chafed or Cut Wires
Insulation worn through at chassis edges or implement bracket rub points, creating intermittent shorts and open circuits. Among the hardest tractor faults to trace without a full harness inspection.
Corroded Connectors
Moisture ingress into Deutsch, AMP, or OEM connectors causing corrosion, high resistance, and circuit failure. Re-pinned and sealed at the connector rather than replacing full harness runs.
Failed Fuse / Relay Blocks
Melted terminals, burned contacts, and failed relays in tractor fuse and relay distribution blocks. Usually the result of sustained overloads or high-resistance connections generating heat over time.
Broken Ground Straps
Missing or corroded chassis ground straps causing voltage offset and intermittent faults across multiple tractor systems. A single bad ground can generate fault codes machine-wide.
Splice Failures
Failed factory or field splices causing voltage drop and signal loss on tractor circuits. Re-spliced using properly rated butt connectors or solder-sleeve joins matched to the circuit load.
Rodent Damage
Chewed insulation from rodents nesting in the tractor cab or engine compartment, often damaging multiple circuits at once. All affected runs located, re-insulated, and re-routed.
Heat-Damaged Harness
Burned or melted runs from contact with exhaust manifolds, turbo housings, or DPF components on modern tractors. Re-routed with heat-resistant loom and proper clipping away from hot surfaces.
Custom Harness Build
New harness fabrication for tractor retrofits, implement upgrades, or obsolete machines where OEM parts are no longer available. Built to spec using Deutsch connectors and agricultural-grade wire.

How a Screen Repair Works

01
Submit & Ship
Fill out a repair request online. We'll confirm receipt and send shipping instructions. Pack the unit securely and put your contact info inside the box.
02
Diagnosis
We power up, test, and run full diagnostics on the unit. You get a written fault report telling you exactly what failed and why.
03
Quote & Approval
We send a firm quote before touching anything. No surprises. If the repair isn't cost-effective we'll tell you honestly and recommend alternatives.
04
Repair & Return
Repair completed, bench-tested, and returned with a service report. We move fast. A screen-down tractor is money lost.

Screen down? Don't replace — repair.

OEM replacement screens for FENDT and other premium brands can run into thousands of dollars. In most cases we can repair your existing unit for significantly less and get it back faster than a new one ships.
