What Does Each LG OLED55B8PTA TV Part Do?

LG OLED55B8PTA Motherboard / Main Board

The LG OLED55B8PTA motherboard controls the main functions of the TV, including HDMI input, USB detection, audio output, video processing, software loading, remote commands and Smart TV functions. If the LG OLED55B8PTA is stuck on logo, restarting, hanging, not detecting HDMI or showing software problems, the motherboard is usually inspected.

LG OLED55B8PTA Power Supply Board / SMPS

The LG OLED55B8PTA power supply board converts AC input power into required DC voltages for the motherboard, backlight and other internal sections. If the LG OLED55B8PTA TV is completely dead, has no standby light, takes time to start or turns off automatically, the SMPS / PSU board should be checked.

LG OLED55B8PTA T-Con Board

The LG OLED55B8PTA T-Con board, also called timing control board, controls image signal transfer between the motherboard and display panel. Vertical lines, horizontal lines, white screen, double image, half display or negative picture can be related to the T-Con board, LVDS cable, FFC cable or panel.

LG OLED55B8PTA LED Driver / Backlight Section

The LG OLED55B8PTA LED driver / backlight section powers the TV screen illumination. If the TV has sound but no picture, or the picture is visible only with torch light, the LED backlight or LED driver section should be inspected.

LG OLED55B8PTA LVDS Cable

The LG OLED55B8PTA LVDS cable carries display signal from the motherboard to the T-Con board or panel section. Loose, damaged or mismatched LVDS cables can cause flickering, no display, wrong colours, screen noise or intermittent picture.

LG OLED55B8PTA FFC Cable

The LG OLED55B8PTA FFC cable is a flat flexible ribbon cable used between panel boards, T-Con board or display sections. Damaged FFC cables can cause half screen, lines, flickering, blank display or panel communication problems.

LG OLED55B8PTA IR Sensor Board

The LG OLED55B8PTA IR sensor board receives remote control signals. If the remote is working but the TV does not respond, the IR sensor board, receiver cable or key button board may need checking.

LG OLED55B8PTA Wi-fi Module

The LG OLED55B8PTA Wi-fi module helps the TV connect to wireless internet. If Wi-fi is not showing, not connecting, disconnecting frequently or network option is missing, the Wi-fi module or motherboard software should be checked.
