Projector White Dots Repair

Starry night effect on your DLP projector? White or dead pixels appearing on screen? This is a failed DMD chip — a very common fault on Optoma, BenQ, Acer and ViewSonic DLP projectors. Our engineers replace the DMD chip with a genuine component, realign the optical block, and calibrate the image. 90-day warranty included.

Projector Power Repair & Overheating Fix

Projector shutting down after 5-10 minutes? Temperature light flashing? Loud fan noise followed by automatic power-off? These are classic overheating symptoms caused by blocked airflow, failed fans, dried thermal paste, or power supply faults. We perform a full thermal overhaul: ultrasonic filter cleaning, fan replacement, thermal paste renewal, and power supply diagnostics.

Projector Display Problem & Discolouration Repair

Yellow, brown or purple stains on your projected image? Flickering colours? Image appearing only in black and white? These symptoms indicate burnt LCD polarizers, a failing colour wheel, or optical block contamination. For LCD projectors we replace all three polarizer films. For DLP projectors we replace the colour wheel and check the colour sensor.

Projector Lamp Replacement

Lamp not striking? Projector turning on then shutting off immediately? Dim image even with a new lamp? We supply and fit genuine OEM lamps for all brands including Epson, Optoma, BenQ, Sony, Panasonic, ViewSonic, NEC and JVC. Every lamp replacement includes a free optical cleaning service.

Projector Colour Wheel Repair

Flickering rainbow colours? Image only showing in black and white? Unusual grinding noise on startup? These are clear signs of a damaged or worn colour wheel in a DLP projector. We replace the colour wheel with a precision-balanced genuine component and recalibrate the colour sensor.

No Signal or No Image Repair

Projector powers on but shows no image? Input sources not detected? HDMI ports not working? These faults can stem from the mainboard, input board, or internal video processing circuits. Our micro-soldering technicians can repair board-level faults that other centres replace entirely.
