Logic Board Repair and Replacement: Signs of Fault & Cost of Service The logic board is the component responsible for translating incoming data into the processing decisions that shape what appears on screen — from how colors are rendered to how quickly the TV responds to an input change. When a television's image looks technically

TV LED Backlight Lenses Repair and Replacement: Signs of Fault & Cost of Service Backlight lenses are small optical components fitted over individual LEDs in full-array backlight systems, spreading each LED's light evenly before it reaches the diffuser and panel above. They are easy to overlook, but when even a handful of lenses crack, discolour,

TV LED Backlight Array Repair and Replacement: Signs of Fault & Cost of Service A full-array LED backlight system places LEDs directly behind the entire panel rather than only along the edges, divided into multiple independently controlled dimming zones for deeper contrast. This more advanced design delivers a better picture than simple edge-lit strips, but

TV Backlight Diffuser Repair and Replacement: Signs of Fault & Cost of Service The backlight diffuser is a translucent sheet positioned between the LED backlighting and the display panel, spreading individual points of light into a smooth, even glow across the entire screen. When this layer is damaged, the picture can develop visible patches or

TV Light Guide Plate Repair and Replacement: Signs of Fault & Cost of Service The light guide plate, often shortened to LGP, is a clear acrylic panel used in edge-lit televisions to channel light from LEDs positioned along the screen's edges evenly across the entire display. Because the whole picture's brightness depends on this single

TV Reflector Sheet Repair and Replacement: Signs of Fault & Cost of Service The reflector sheet is a thin, highly reflective layer positioned behind the light guide plate or LED array, bouncing stray light forward toward the panel instead of letting it escape and go to waste. It is one of the least glamorous components

TV Backlight Driver Repair and Replacement: Signs of Fault & Cost of Service The backlight driver is the small circuit responsible for regulating the voltage and current delivered to a television's LED backlighting, whether that backlighting is arranged in edge-lit strips or a full array. When this driver fails, the panel and main electronics often

TV Inverter Board Repair and Replacement: Signs of Fault & Cost of Service The inverter board is found in older CCFL-backlit LCD televisions, where its job is to convert low-voltage DC power into the higher-voltage AC needed to light the fluorescent backlight tubes. As CCFL technology has largely been phased out in favour of LED

T-Con Board Repair and Replacement: Signs of Fault & Cost of Service The T-Con (timing control) board sits between the mainboard and the display panel, converting incoming video data into the precise row-by-row and column-by-column instructions the panel needs to render an image. When a TV shows lines, static-like patterns, or a half-working screen, T-Con

Timing Controller Board Repair and Replacement: Signs of Fault & Cost of Service Closely related to the T-Con board but worth treating on its own, the timing controller board governs the exact refresh rate and frame synchronization the panel uses to display motion smoothly. When motion looks judder-prone, frames appear mismatched, or colors shift briefly

TV Power Supply Board Repair and Replacement: Signs of Fault & Cost of Service The power supply board takes incoming mains electricity and converts it into the various regulated DC voltages that every other component inside the television depends on, from the main board to the backlight system. Because nothing else in the set can

TV Power Supply Unit Repair and Replacement: Signs of Fault & Cost of Service The power supply unit refers to the complete power module inside a television — the board itself along with its housing, connectors, and protective circuitry — as it is typically sold and swapped when a full replacement is needed. While closely
