You must place the N * on the TV chassis and form the exact location of that diode. This will facilitate the search.

Hi. If you refer to diode D 812 that goes to the source mosfet is a diode ERA81-004: 45V ... 1A ... 500nS. SCHOTTKY diode. What's wrong with this short? source circuit http://i.imgur.com/tflbZ.jpg

I tell you, I measure it, it marks me continuity, I took it out of the board, it marked me well, the issue was that the resistance had flown the R632 and the mosfet and the TV didn´t turn on, I didn´t have any idea about the diode of the choper friend I find the fault that causes the source to not start because of that

If I saw the other topic you have.
That's how I answered you about that diode. Rate the contribution and if you see that it is correct how it was solved.
Fashion the diode in 200M scale if you have and continuity

with the repairs they stop answering me and I have to fix myself only if this is a forum to help people because you are professional then do not criticize or do gossip dedicate yourself to helping people who need a hand and as I said before if I opened other post is because I do not have the solution because they leave me hanging and they do not answer me more for that reason nothing else I do not do it on purpose who wants to understand my answer to do it and the one that does not answer me anymore

Miguel if it goes against the rules of the forum that the administrator sanctions me or throws me from the forum but you who are the owner of the forum friend there are so many worse things that go against the rules do not put yourself in exquisite ok and I no longer care that if the future is still here you don't bother to answer me and I hope it will be that way in the future

if the people who ask here would be specialized, they would not need the forum to ask victor or necro2 or warnieri or alismo luis tartaglia and all the technicians who are here who are teachers in the field if they need to ask questions they do not answer and help people that is not as professional as they are, but good for me, so help the people who need them the rest, the redundancy is more valuable and now they want to kick me out of the forum.

That solved well, I commented what was the reason for the source that did not turn on, so it remains in the forum for a colleague who needs to know about this fault, greetings

Quiet mane. What you have to do when you don't have quick answers. It is making a new comment on your question. It's like reliving the question. And if they want to help you they will. If they do not hold on, there is no other that you will do. This happens to many. You are not the only one. And what the colleague tells you is correct, don't take it badly. It may sound that it is bad as it is said. But I think it is not. It is mostly advice.

Hi friends, I don't find the fault with this TV, I don't have a tendency anywhere just in the main capacitor 334V, after the rest of the source I have 8V and I don't know where the fault can be, friends.
