Hello to all! I am a beginner, this morning I was doing a repair (a little weld on the backlight fuse - that with the spot) I accidentally touched with the welder another component, I would like to identify and replace but there is no value written on it. How I can identify it? unfortunately my fault I not removed the battery while operate, could be severe demage? please help me, I was working and now I can not continue. I turn to you because in my hometown nobody knows how to do (???) Thank you all in advance.
