You would need to identify them by trial and error, or by following guides from others who have successfully used this method. Once connected, you may be able to access the console and enter commands like recovery to attempt a system restore, similar to how it's done on an Android phone. This method is not recommended for beginners. Always source your firmware downloads exclusively from the
If the standard USB method fails, more serious corruption may be present. For such cases, professionals use a UART serial adapter to communicate directly with the board's processor. This is a complex process that requires identifying the unmarked TX, RX, and GND pins on the board. Commands like recovery can then be used in a terminal program on a PC to force the TV into a recovery mode to restore the system. This method is recommended only for advanced users with experience in hardware debugging.
