Hello colleagues, I enter the workshop, this screen model which shows the logo as soon as it turns on and then goes to black but with sound and image if one illuminates it, if any has real data I will punctuate as usual, I have already made all the measurements and the visual check and presents nothing short, or burned in sight only the voltages that appear and fade instantly, not leaving the screen active. Greetings to all!

Hello Victor, and probe bar by bar was the first thing I did and they are all all right without problems! You will have if you are so kind the number of the integrated circuit that commands the voltage and protection of the LEDs is marked with the number of IC 801, Remember that it corresponds to the source plate of LG 47 LA6200, the brand of nuts in the integrated circuit is really illegible, and there is no way to lower the technical service circuits, I would appreciate if you could send me the number of said controller.
Thank you in advance!
