InFocus Projector
Repair Centre.
From the ubiquitous IN110 Classroom Series to high-brightness IN5100 Large Venue units. We provide component-level diagnostics for DMD chip failures, noisy colour wheels, and mainboard faults.
Common InFocus Faults & Fixes
InFocus heavily utilises DLP (Digital Light Processing) technology across its commercial and educational fleets. While highly robust, the fast-moving mechanical parts require scheduled maintenance to prevent catastrophic failure.
White Dots (DMD Chip)
The "Starry Night" effect is very common in the IN110 and IN119 series. Heat stress causes the microscopic mirrors on the TI DLP chip to seize. We replace the DMD chip and upgrade the thermal compound.
Colour Wheel Whine
A loud, high-pitched screeching or buzzing noise points to a drying colour wheel bearing. If not replaced, the wheel will shatter, severely damaging the internal optical light tunnel. We replace the full wheel assembly.
Thermal Shutdowns
If the projector turns off after a few minutes and flashes the Temp light, the internal airflow is restricted. We perform a complete ultrasonic clean of the chassis, fans, and heatsinks to restore safe operating temperatures.
Ballast / No Ignition
A repetitive clicking noise with no light indicates a high-voltage ballast failure. If the unit is entirely dead, it points to the primary PSU. We perform component-level micro-soldering to revive these boards.
Corporate Fleet Maintenance: Ceiling-mounted InFocus units in meeting rooms or classrooms absorb rising heat and dust over years of operation. Routine filter changes alone do not prevent DMD chip death; the internal fans must be regularly serviced. We offer SLA contracts to manage this proactively.
InFocus Error Code Database
InFocus projectors typically utilise a combination of Power, Temp, and Lamp / Wrench LED lights to communicate hardware faults.
| LED Indicator State | Indicated Fault | Engineer's Recommendation |
|---|---|---|
|
Temp: Flashing Red
Power: Blue/Green Solid
|
Overheating Shutdown | The internal thermal sensors detect excessive heat. Let it cool. If it happens repeatedly within 10 minutes, an internal fan has likely seized or degraded. |
|
Lamp: Red Solid
Power: Red Solid
|
Lamp / Ballast Error | The projector cannot strike the lamp arc. First, ensure the lamp door is screwed on tightly (it presses a safety microswitch). If tight, the bulb is blown or the ballast board has failed. |
|
Temp: Flashing Red
Lamp/Wrench: Flashing Red
|
Fan Lock Failure | A critical cooling fan is not spinning. The unit instantly cuts power to the lamp to prevent a fire hazard. The faulty fan must be identified and replaced. |
| Loud Screeching Noise | Colour Wheel Failure | The optical sensor cannot read the index mark on the colour wheel, or the wheel bearing is dry. The wheel is either stuck, spinning at the wrong speed, or shattered. Requires immediate repair. |
| Completely Dead | Main Power Supply (PSU) | No standby lights whatsoever. A power surge has likely blown the internal ceramic fuse or primary bridge rectifier. We perform component-level soldering to revive the board. |

Free Projector Recycling
Is your legacy InFocus projector beyond economical repair? Don't send it to landfill. We offer a completely free, eco-friendly recycling service. We safely extract hazardous mercury from old UHP lamps and ensure zero-to-landfill processing for plastics and metals.
Recycle NowDon't Throw It Away.
A noisy colour wheel or white dots on the screen do not mean your InFocus is dead. A professional component replacement costs a fraction of upgrading your entire AV fleet.
