emh1980 Posted May 22, 2018 Share Posted May 22, 2018 Hi, community, someone has the schematics manual? I have in short circuit the integrated U9, number 2374, located on the main board. I can not find the spare because I can not find the generic name Can anyone help me? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted May 22, 2018 Share Posted May 22, 2018 1) Schematics are not available to the public. 2) If that chip is blown then some other items got blown with it. 3) If the trace is damaged, whatever PCB trace repair you might be able to do won't last.

So I throw it in the trash and buy another one? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted May 22, 2018 Share Posted May 22, 2018 Unfortunately,... yes. There are two chips and/or an inductor, that if they go, it's a lost cause. And that chip is one of the two. I only know about this because as a repair tech here, I've been inside more of these than most, just to analyze the failures. Some things are fixable on these, but unfortunately that isn't one of them. Quote Link to comment Share on other sites More sharing options...
emh1980 Posted May 23, 2018 Author Share Posted May 23, 2018 Would it be possible for you to give me the generic name of the integrated circuit? so I have my last chance before throwing it away. best regards Quote Link to comment Share on other sites More sharing options...
psarkissian Posted May 23, 2018 Share Posted May 23, 2018 I can't get into or advise on circuit level stuff any further than I have. And as I mentioned before, if that chip goes it's because something else failed and took out that chip. So if that chip goes, then there are multiple fail points.
