  • In service menu, enable Debug mode for the RS232 port AND disable watchdog.
With TV switched off, press the following sequence on the remote: [INFO] [MENU] [MUTE] [POWER]
Enter the Control menu (then enter Sub Option) and set the value of the RS232 mode to Debug. Also set Watchdog to OFF.
Once you're back to the main Service menu, you will have to power off the TV for normal operation.
Notice that your TV will reset RS232 mode back to UART when you install another firmware (no matter if it's older or newer).
If you don't feel capable of soldering such a cable, you can find and buy a cheap (under $5) USB to TTL adapter at eBay.
