I used that cap as a 30 second test, just to see what happens. Exact same scenario.

So do u get this tv working by adding a new main board?

I suggest you read through the thread again.

I know this solution won't apply to most people with this problem with this TV, but this is what worked for me.
My LD3288M would sometimes go on, but then when turned off, it would stay off. No power LED, no sound, no image on the screen, and no back light.
I saw it had a BGA chip on the main board. I did the heat gun on it up to 200 deg. C. There was no change in the problem behavior.
After about a week, I went back to take another look at it before it went to the recycler.
I disconnected the T-Con board and took an eraser on the connectors. I also saw the cable between the main board, and the T-Con was taped down at a tight position that seemed to create some stress at the connectors. I released the tape to give it a bit of slack, and when I put it back together, it worked. It hasn't had the power up issue for about 4 days now.
The only other thing that changed that I can think of is that we don't have the summer weather anymore, so perhaps the cooler air in the house helped. I didn't feel anything getting too warm before though.
I know this isn't a clear solution, but there have been stranger fixes to electronic equipment.
