Forensic Engineering

Precision Diagnostics.
Transparent Pricing.

We believe in the "Quote-First" protocol. You cannot price a repair accurately until you understand the root cause. We strip, test, and diagnose your Epson projector to the component level before you spend a penny on parts.

Why Bench Diagnostics Matter

Modern Epson projectors are sophisticated opto-electronic devices. A simple symptom like "It won't turn on" can be caused by a 50p fuse, a £40 capacitor, or a £500 mainboard. Guesswork is expensive.

Generic repair shops often just swap boards, passing the high cost of sub-assemblies onto you. Our approach is different. We use oscilloscopes to trace voltage rails, thermal cameras to spot overheating ICs, and pattern generators to check optical alignment. By identifying the exact component failure, we can often repair the board rather than replace it, reducing your bill by up to 60%.

  • ISO-Standard Clean Room for optical engine disassembly.
  • Vacuum Refill Rigs for high-end laser cooling loops.
  • Firmware Analysis to check for logic-level corruption.

Check intake filters & intake thermistor

Classroom projectors live in harsh environments. Chalk dust, marker pen volatiles, and limited ventilation are the primary killers.

Our Diagnostic Protocol:

We do not just check if it turns on. We strip the unit to inspect the Internal Air Tunnels. Often, a projector showing a "Lamp Error" actually has a ballast suffocated by dust, causing it to overheat and cut voltage.

For Laser models (EB-700/L200 series) used in schools, we inspect the phosphor wheel for chemical clouding caused by whiteboard marker fumes—a specific issue that dims the image permanently if not chemically cleaned.

Corporate & Enterprise Diagnostics

In the boardroom, reliability is currency. Corporate projectors (EB-2250U, EB-L600) typically suffer from electrical fatigue rather than dust.

Our Diagnostic Protocol:

We focus on Signal Integrity and Power Regulation. If your projector drops signal or flickers during a presentation, we test the HDMI EDID chips and the Digital Formatter board. We also load-test the Power Supply Unit (PSU) capacitors.

Intermittent shutdowns in this sector are often caused by the PFC (Power Factor Correction) circuit struggling with "dirty" mains power often found in large office blocks. We use mains analysers to verify if the projector's internal protection is triggering too sensitively.

Diode Bank / Liquid Loop Failure

High-brightness projectors (10,000+ lumens) are not just electronics; they are hydraulic systems. The EB-L and EB-PU series rely on Glycol Liquid Cooling.

Our Advanced Diagnostic Protocol:

  • 1. Pressure Testing: We connect the liquid loop to external gauges to check for pump cavitation or micro-leaks in the radiator.
  • 2. Chemical Analysis: We inspect the coolant for acidity (galvanic corrosion) which clogs the heat exchangers.
  • 3. Laser Bank Integrity: We test individual laser banks to distinguish between a failed diode array (rare) and a failed driver board (common), potentially saving £2,000+.

Transparent Pricing Structure

We charge a standardized Bench Diagnostic Fee. If you proceed with the repair, we often absorb this fee into the final cost.

1. Collection

Secure logistics

We arrange DPD or DHL collection. For large venue units, we use pallet couriers to ensure safety.

CORE

2. Diagnosis

The Assessment

Full strip-down and report. You receive a quote for parts & labour. No obligation to proceed.

3. Repair

The Fix

If approved, we repair, clean, and soak-test. If declined, we simply return the unit (return carriage applies).

Diagnostic FAQs

Why can't you give me a firm price over the phone?
Epson projectors share error codes. A "Temp Error" could be a £20 fan or a £300 mainboard sensor circuit. Without physically testing the voltage rails and thermal sensors, any price given over the phone would be a guess. We prefer to give you an accurate, guaranteed price after inspection.
Do you charge if I don't go ahead?
We operate a "No Fix, No Fee" policy on the labour itself. If the unit is irreparable, or if you decide the parts cost is too high, you do not pay for the engineer's diagnostic time. You typically only cover the shipping costs to return the unit to you.
How long does the assessment take?
Once the unit arrives at our secure facility, we aim to have a diagnostic report and quote to you within 24-48 hours. High-end laser units requiring liquid loop testing may take an additional 24 hours for pressure verification.
