Sofy I confuse your answers, test, when you give the order to turn on the screen, "turn on normal", does it have sound, does it change channels? , but it does not turn on the lighting, because as you already checked the lighting turns on, but without the monitoring (supervision) of the main card, it indicates if this comment is correct
yes friend is correct what you indicate
Look then friend gilar the main fault is that the TV turns on and everything but the lamps do not connect the cable signal and if you hear and change everything normal but the lamps do not turn on ....
on the other hand when doing the test that you indicated in the photo the lamps do turn on but without the mainboard as you indicated now well friend you think that changing the main is the solution or there is another way to solve this ..
Thank you in advance for your kind time and patience to explain
Perfect, all clarified, not your defect is not in the main card, it is the inverter, some lamp consumes more than what is established and that is why it comes into protection, we will decrease this protection, but I need you to publish the controller number of lighting contained in the inverter section
