Projector Maintenance Service: Restore Brightness & Extend Life
Heat and dust are the enemies of all projectors. Our workshop-grade maintenance service removes internal contamination, restores cooling efficiency, and brings the "pop" back to your image.
Specialist care for Xiaomi, Hisense, Samsung, Leica, and 4K Laser TV systems.
Why Maintenance Matters
A projector is a high-performance air filter that also creates light.
The Dust Cycle
Projectors circulate massive amounts of air to cool the laser and power supply. Over time, micro-dust bypasses filters and settles on the DMD chip, lenses, and mirrors.
This creates a hazy, washed-out image (often mistaken for a "dying bulb" or laser) and insulates components, leading to overheating.
Thermal Stress
Thermal paste dries out after 2-3 years. When this happens, the heat from the laser cannot transfer to the heatsink efficiently.
The result? Fans scream at 100% speed, the system throttles brightness, and eventually, the mainboard fails.
⚠️ CRITICAL WARNING: Do Not Use Compressed Air
Never blow compressed air into a projector's vents. This does not clean it. Instead, it forces loose dust deep into the sealed optical block and onto the DMD chip/LCD panels, creating permanent black spots or a "starry night" effect that is expensive to repair.
What a Full Service Includes
1. Optical Deep Clean
We strip the unit down to the optical core.
- Ultrasonic cleaning of colour wheels.
- Chemical cleaning of lens elements.
- DMD/LCD panel surface cleaning.
- Light tunnel polishing.
2. Thermal Overhaul
Restoring cooling efficiency to factory spec.
- New high-grade thermal paste application.
- Replacement of dried thermal pads.
- Fan blade de-fouling and bearing lubrication.
- Heatsink fin clearing.
3. System Verification
Ensuring stability before return.
- Firmware updates (if stable/required).
- Sensor calibration (Thermal/Fan).
- Focus and alignment geometry checks.
- 4-hour heat soak test.
Common Questions
Most issues can be prevented with timely care.
How often should I service my projector?
For heavy users (TV replacement), every 18-24 months. For occasional movie viewing, every 3 years.
My picture is cloudy/hazy. Is it broken?
Likely not broken, just dirty. A layer of dust on the optics scatters light, killing contrast. A service usually restores this.
Why is my fan so loud?
If thermal paste is dry or vents are clogged, the projector thinks it is overheating and runs fans at max speed to survive. A thermal service fixes this.
