Before concluding the board is dead, technicians must check the voltage levels. Common testing points on the TP.MS3458.PC757 Typically 5V or 3.3V. Main Voltage: 12V or 24V (depending on the panel size).
Locate specific MOSFETs or capacitors that may have shorted. tpms3458pc757 service manual
No LF Signal Output: The LF driver chip (U12) or the copper coil antenna is damaged or open-circuited. Measure coil resistance; normal value should be roughly 1.8 to 2.5 ohms.

Download the verified firmware binary ( .bin ) file provided by the system OEM.
In some TV designs, the motherboard communicates with other modules. If the motherboard is replaced, you might need to perform a reset procedure. While this is more common in automotive TPMS systems, some TV mainboards may require a factory reset via a specific button combination or a firmware reflash.
Re-flash the SPI Flash memory using a programmer (e.g., CH341A) with the correct dump file. TV Parts Today Before concluding the board is
Apply a stable 24V DC power source to the module and allow a 5-minute warm-up period.
Drop a comment below—I’ve decoded the full error log structure from the manual and can help you interpret your LED flash codes.
If the manual shows a 20-pin ribbon cable and your device uses a flex PCB, you likely have the wrong manual.
