The TP.MS3458.PC757 is a widely used triple-network smart LED TV mainboard. It integrates the power supply unit (PSU), LED backlight driver, and ATV/DTV motherboard into a single printed circuit board (PCB). This design is highly cost-effective for manufacturers but requires specific troubleshooting steps when a component fails. Technical Specifications and Architecture

The is a widely used "3-in-1" (main, power, and LED driver) motherboard primarily found in 4K LED TVs from brands like RCA, Avera, Haier, and iLive. Because it integrates the power supply and backlight driver onto a single PCB, troubleshooting requires a firm understanding of both high-voltage AC circuits and low-voltage digital processing. Essential Technical Specifications Use the exact string "TP

This motherboard is designed for medium-to-large panel sizes, typically ranging from . Resolution Support: Ultra High Definition (4K). Chassis Type: Often associated with the MSD3458 chassis.

MediaTek/MSTAR Processor (typically MS3458 family) Supported Screen Sizes: 32" to 43" LED Panels
