Thank you very much Tobias, I'm going to replace it to see if it's just that, or have any other problems.

give it, make sure you don't have a short one at the exit, if that's how we study it, luckily it's just that :)

Hi Tobias TV, I have removed the broken component, and I have continuity, between the large pin that goes behind, and two of the pins on the other side, the one in the center, and the one below, if you look at it as it is in the photo ... I had prepared a photo indicating it but I don't know how to put it here ... is it correct? ... thanks.

You can upload it from the notebook in your question, now I upload a photo, I will focus on U104, 108 you don't have it, it must be another version

Maybe you have a short at the exit, if so, I indicate a practice to detect it

without the regulator I measured on C113 if the 3.3 volt line is short, be careful, you have a resistance of 330 ohms to ground, do not be confused with that reading

C113 seems to me or is it swollen? If so, is your problem;)

In addition I just saw another burned component .. the L303, the 703 has a hole in the top, like a perforation.

U703 is the one that presents the perforation at the top is an 8-pin component near c113

the U703 is the eeprom, it happens that it does not go with a virgin, there is recorded the firmware of the TV, you are complicated with that main :(

Well, you only see the little hole, it does not look burned, if there is any luck, the c113 if I think you are right, it is unhappy, I will change it, I do not have an equal u104 .. to know how I get it I have a similar one but of 2.9 v as I saw in the datasheet.

Surely on L303 the problem came, according to the boy, it broke when his son was connecting the play ..
