Thank you once again for your answer. in relation to the chip, unfortunately, when the piece was burned, the first letter was also destroyed, which after my deduction from the remaining half of the inscription I considered to be the letter L. I tried to look for this configuration on the Internet but I couldn't find anything, I think it should be something other than a mosfet and be what you think, a chip with many diodes. I also found this, but there seem to be five versions of it, but not with this inscription on it. I am attaching a diagram, I apologize that it is not very clear.
