Restoring the Magic of Your Home Cinema
Your home cinema is the heart of your entertainment. When it fails, you need a specialist, not just a general repair shop. Whether you own a dedicated 4K Sony SXRD theatre room unit or a portable BenQ DLP projector, we treat every unit with the precision it deserves.
We resolve complex thermal and optical issues daily, from the "white dots" of failing DMD chips to degraded polarizers causing picture tinting. Our component-level service restores factory specifications using genuine OEM parts, saving you the cost of a replacement machine while retaining your original brightness and contrast.
- Free diagnosis options available for drop-in customers.
- Genuine OSRAM and Philips lamps in stock.
- 90 days standard warranty on all major optical repairs.
Overheating & Shutdowns
If your projector turns off after a few minutes or the fans spin loudly, the cooling channels are likely blocked. We perform deep ultrasonic cleaning.
White/Black Dots (DMD)
Specific to DLP projectors (Optoma, Acer, BenQ). We replace the faulty DMD chip to restore a flawless, crystal-clear picture.
Discolouration
Yellow stains or purple lines often indicate LCD panel or polarizer failure. We realign or replace the optical engine components.
Power & Ballast
No lights? Blinking red LEDs? It might not be the lamp. We repair mainboards and ballast units at the circuit level.
Colour Wheel Repair
Experiencing loud whirring noises or flickering rainbow colours? We replace shattered or seized colour wheel sensors in DLP units.
Faulty Input Ports
No Signal? We repair loose or damaged HDMI, DVI, and VGA ports soldered directly to the mainboard, restoring full connectivity.
Strategic Maintenance for Education & Business
For schools and businesses, equipment failure disrupts critical operations. As the trusted partner for the Ministry of Defence and Education sectors, we understand the specific demands of heavy usage cycles and rapid turnaround times.
Case Study: University Lecture Hall
Scenario: A major UK university's 12,000 Lumen Panasonic Laser unit dimmed by 60% after 4 years of "maintenance-free" use.
Solution: Instead of a £15k replacement, our team performed a liquid cooling flush and radiator sonic bath.
Result: Restored to 90% brightness for <10% of the replacement cost.
Our Preventative Maintenance Contracts extend fleet lifespans significantly. Through annual deep cleaning and firmware updates, we reduce failure rates by up to 60% for interactive whiteboards and large venue laser units. We simplify the entire logistics process with automated tracking and centralised invoicing.
Dedicated B2B Portal
Manage assets, track repairs in real-time, and download invoices instantly.
Open a Corporate AccountPurchase Orders
We accept official POs from all UK Schools, Universities, NHS trusts, and Local Councils with 30-day terms.
Collection Service
Our dedicated logistics partners (DPD/UPS) can collect fleet repairs directly from your reception desk.
Data Security
Trusted by the MOD. All equipment is handled in a secure environment with strict privacy protocols.
Free Loan Units
For critical boardroom or lecture hall infrastructure, we can provide loan units to keep you operational.
Mastery of Light & Projection
We don't just change lamps. Our engineers are trained on the component level for every major projection technology available today.
Light Source Technologies
Laser Phosphor
Solid-state illumination for maintenance-free operation in large venues. We service the phosphor wheels and laser banks.
RGB Laser
Pure laser light for premium cinema. We calibrate colour gamuts and repair cooling systems for these high-heat units.
UHP/Xenon
Traditional high-pressure mercury lamps. We fix ballast ignition issues and provide genuine replacements.
LED Solid State
Portable and business units. We repair power driver boards and LED module failures for instant-on devices.
Imaging & Optical Systems
DMD / DLP
Digital Micromirror Devices. We are experts in replacing faulty DMD chips that cause white or black dead pixels.
3LCD Technology
We perform precise realignment of LCD panels and replace degraded polarizers to fix yellow/blue tinting.
LCoS / SXRD
Liquid Crystal on Silicon. High-end Sony & JVC repair specialists for contrast loss and gamma drift issues.
Optical Engines
Complete optical path cleaning and lens assembly repair to remove dust blobs and restore focus uniformity.
High-End Laser & 4K Specialist Repair
Beyond standard lamp units, we possess the clean-room facilities and diagnostic software required to service flagship laser projection systems from top-tier manufacturers.
Liquid Cooling Systems
Flagship models from Panasonic (PT-RQ) and Christie (Griffyn) use glycol-based cooling. We perform coolant flushes, radiator chemical cleaning, and pump replacements to prevent thermal shutdowns.
Phosphor Wheel Mechanics
We replace worn ceramic bearings and degraded phosphor segments that cause colour shifting and high-pitched mechanical whine in laser engines.
4K Pixel-Shift Actuators
Servicing the delicate e-shift glass vibration mechanisms in JVC and Epson 4K Pro-UHD units to resolve buzzing noises and soft image focus.
Sealed Optical Blocks
"Sealed" does not mean dust-proof. We perform IP5X/IP6X compliant disassembly in a filtered air environment to remove fine particulate ingress without introducing new contaminants.
The "Maintenance-Free" Myth
Many organisations purchase laser projectors believing the "20,000 hours maintenance-free" marketing claim. While the laser light source may last that long, the system supporting it does not.
Thermal Throttling
As dust coats the internal radiators, the system automatically reduces laser power to protect the diodes. Your 10,000-lumen projector quietly becomes a 6,000-lumen unit to survive.
Catastrophic Failure
Without maintenance, liquid cooling pumps seize and fans fail long before the 20,000-hour mark. A £15,000 asset can be written off due to a lack of a £200 service.
Engineering Standard Deep Clean
We go beyond a simple "air dust". Our 25-point service protocol ensures every unit is returned to factory thermal specifications.
ESD Safe Disassembly
Full strip-down on anti-static mats to protect sensitive DMD logic boards.
Ultrasonic Bath
Optical lenses and colour wheels are chemically cleaned in ultrasonic tanks to remove nicotine/smoke residue.
Thermal Renewal
Old, dried thermal paste is replaced with industrial-grade high-conductivity compound.
Soak Test & QA
4-hour run time under full load to verify thermal stability before PAT testing.
