Code : BN41-02038D
Model : BN41-02038
Defect: the TV turns on and asks for the One-Connect connection, once connected, it goes into a continuous loop, the Smart TV writing appears, for a few seconds and the boot cycle starts again from the beginning.
I'm trying to enter service mode (INFO-Menu-MUTE-POWER ON), to load the firmware from USB and enable the SUBMICOM UPGRADE option to ON, an operation already performed with other Samsung models, but on this TV there is no way to enter service.
I also tried the MENU-182-POWER ON sequence, but when you press button 1 the TV turns on.
Using a serial RS 232 cable with Hyperterminal I have the following log, which I attach
Thanks for the advice.
