TV Repair Course

Lesson 1 • Workplace Safety and ESD Prevention

Establishes safe handling of high-voltage circuits, capacitor discharge, and electrostatic-sensitive parts. Safe practices protect both the technician and the equipment under repair.

Lesson 2 • Core TV System Architecture

Maps the signal path from antenna or HDMI input through processing to display output. Students trace how each subsystem depends on the others.

Lesson 3 • Identifying Major Internal Components

Teaches visual recognition of boards, connectors, and passive components inside a TV chassis. Accurate identification prevents misdiagnosis and incorrect part replacement.

Lesson 4 • History and Evolution of TV Sets

Traces CRT, plasma, LCD, LED, and OLED development to contextualise repair challenges. Understanding generational differences guides part sourcing and diagnostic strategy.

Lesson 1 • Multimeter Mastery

Teaches voltage, resistance, continuity, and diode-mode measurements on live and de-energised circuits. Multimeter proficiency is the single most-used diagnostic skill in TV repair.

Lesson 2 • Hand Tools for TV Disassembly

Covers screwdrivers, spudgers, pry tools, and torque requirements for TV chassis. Correct tool selection prevents stripped screws and cracked bezels.

Lesson 3 • Soldering and Rework Equipment

Covers soldering stations, hot-air rework tools, flux types, and solder alloys used in TV board repair. Equipment quality directly affects joint reliability and component survival.

Lesson 4 • Specialised TV Diagnostic Tools

Introduces backlight testers, LVDS signal generators, and pattern generators for panel evaluation. Specialised tools reduce guesswork and speed up panel-level diagnosis.

Lesson 1 • Reverse Engineering Without Schematics

Provides strategies for tracing circuits on boards lacking published documentation. Component markings, datasheet lookup, and circuit topology inference fill documentation gaps.

Lesson 2 • Locating and Using Service Manuals

Explains how to find manufacturer service manuals, exploded-view diagrams, and part lists online. Reliable documentation access cuts diagnostic time significantly.

Lesson 3 • Test Points and Reference Values

Shows how to identify labelled test points and compare measured values against service manual specs. Deviation from reference values pinpoints faulty stages quickly.

Lesson 4 • Understanding Schematic Symbols

Identifies resistors, capacitors, inductors, diodes, transistors, and ICs on circuit diagrams. Symbol fluency is prerequisite to tracing any TV circuit path.

Lesson 1 • Power Supply Reassembly and Verification

Guides safe power-up after repair using a series light-bulb limiter and staged voltage checks. Verification confirms all rails are within spec before reconnecting the main board.

Lesson 2 • Systematic Power Supply Testing

Applies multimeter and oscilloscope measurements to isolate faults to specific power supply stages. A structured test sequence prevents misdiagnosis and component damage.

Lesson 3 • Common Power Supply Failure Modes

Catalogues blown fuses, failed capacitors, shorted MOSFETs, and open primary resistors as typical faults. Pattern recognition accelerates diagnosis and reduces unnecessary board replacement.

Lesson 4 • Replacing Capacitors and Semiconductors

Covers capacitor ESR testing, correct replacement selection, and safe MOSFET substitution. Proper component matching ensures long-term repair reliability.

Lesson 1 • CCFL Inverter Repair

Covers inverter transformer testing, capacitor replacement, and CCFL tube substitution for older sets. CCFL repair extends the life of legacy TVs still in active use.

Lesson 2 • Backlight Technology Overview

Compares CCFL tube arrays with edge-lit and direct-lit LED configurations used across TV generations. Technology awareness guides correct diagnostic approach and part sourcing.

Lesson 3 • Diagnosing Dark Screen Faults

Uses flashlight test, voltage checks, and backlight tester to distinguish panel, backlight, and T-con faults. Correct fault isolation prevents replacing the wrong assembly.

Lesson 4 • Backlight Calibration and Testing

Verifies uniform brightness, correct PWM dimming response, and absence of flicker after repair. Calibration ensures customer satisfaction and prevents premature return failures.

Lesson 1 • BGA and SMD Component Rework

Introduces hot-air reflowing of BGA ICs and SMD component replacement on main and T-con boards. Rework skills recover boards that appear beyond repair due to cold joints.

Lesson 2 • T-Con Board Diagnosis and Repair

Tests T-con supply voltages, LVDS input, and gate driver outputs to isolate timing controller faults. T-con failures produce characteristic half-screen, line, or colour-shift symptoms.

Lesson 3 • Diagnosing No-Sound Faults

Isolates audio faults to the amplifier IC, speaker output stage, or digital audio processor using signal injection. Audio diagnosis follows a source-to-speaker signal chain approach.

Lesson 4 • Main Board Functional Blocks

Maps the main board's tuner, demodulator, scaler, audio processor, and MCU sections. Block-level understanding directs probing to the correct circuit area.

Lesson 1 • Panel Replacement Procedure

Guides full panel swap including optical layer transfer, connector migration, and alignment. Correct procedure prevents new panel damage during installation.

Lesson 2 • Ribbon Cable and COF Repair

Addresses broken source driver ribbon cables and chip-on-film connections causing line faults. Ribbon repair is a cost-effective alternative to full panel replacement.

Lesson 3 • OLED Panel Fault Characteristics

Explains burn-in, pixel degradation, and OLED-specific failure patterns distinct from LCD faults. OLED awareness prevents misdiagnosis and sets correct customer expectations.

Lesson 4 • LCD Panel Defect Classification

Categorises vertical lines, horizontal lines, black spots, and pressure damage as panel-origin faults. Accurate classification determines whether repair or panel replacement is viable.

Lesson 1 • Service Menu Navigation and Calibration

Accesses hidden service menus to adjust white balance, panel settings, and diagnostic modes. Service menu mastery enables calibration after board or panel replacement.

Lesson 2 • Smart TV Operating System Basics

Introduces embedded Linux and proprietary OS platforms, boot sequences, and storage architecture. OS awareness is prerequisite to diagnosing software-origin symptoms.

Lesson 3 • Advanced Fault Logging and Remote Diagnostics

Uses built-in diagnostic logs, error codes, and remote access tools to identify recurring faults. Log analysis supports warranty claims and guides preventive repair strategies.

Lesson 4 • Network and Connectivity Fault Diagnosis

Diagnoses Wi-Fi module, Ethernet port, and Bluetooth adapter faults causing smart feature failures. Connectivity repair restores streaming and app functionality customers rely on.
