Please attach good clear pictures of the board so we can see what we are dealing with.

Here are some pictures. Let me know if you want to see anything else.

At the risk of sounding like a half a$$ed fix.. When i cant ID a part like that I usually look for an exact size match off a donor board, 9 times out of 10 the value is close enough that the circuit just dosent care.

What is the P/N of that ICD3?
i should be the same capacitance of the cap used on the left side of the board where it is connected to the same type of 6-pin IC on the left side..

Great thinking. I will look.

The part numbers on the left are all the same less the 30. so CD3011 should be the same as CD11. I will see if I can get it off without killing it.

Does the tcon work without the cap ? You may have other problems beside it.

I have not tried it yet. I was going to hook it up to my bench supply and see if it has any other shorts. I have a replacement on the way. I like to try and fix things like this to learn.

Re: UN65HU9000 T-con

I was able to hookup 12 volts to the board and nothing over heated. I have a new hot air station coming. I will see if I can find out what value CD3011 is.

It is a 10uƒ. With 12 volts applied the current is even lower then before I replaced it.

That has done the trick. It is working. I will let it run for eight hours tomorrow with the cove on to see how it goes.
