Discussion about firmware update for a Thomson 55UA6406W TV with chassis 40-NT67ES-MAC4HG, LCD panel LVU550NDEL, and software V8-NT67F01-LF1V378. A newer firmware version V8-NT67F01-LF1V509 was shared along with an upgrade link, and the update completed successfully. However, the TV still showed the brand logo every minute with constant backlight, leading to the conclusion that the main board may be faulty. Later replies mainly requested the same firmware again after links expired, and one user asked for a USB recovery firmware for a Thomson 55UG6300.
