Thank you for the help BigMig.
Well, I´ve tryied everything you suggested and the tank still bad. As you mentioned,I probably mixed the MB and its transmiters boards but i tryied the transmitter board form the bad tank in another and its operate. Other point: When i turn on the tank, I can hear a noise, coming from the speaker, when the lights are blinking. Thank you for the suggestion of replace the set of board instead of one only. I will try with my another transmitter boards and write down here tomorrow night.
Thank you again BigMig, Jeferson
