Good afternoon, For me there was no need to change the microphone, it is understood that I should have done the change for an identical one, it is understood that it is a somewhat delicate task ...? Now the fault seems to be bandage mode or glass mode or demonstration mode, as it is called ... It has to be taken with the original TV remote control, if there was the possibility of taking something out, I would have gone through the memory, Of course always looking for the firmware that is recorded in it
