Yep, that is why the IC burnt up, Q1 was feeding that shorted out D207, the protection (Vout sense pin) did not act fast enough to turn off Q1.

Now I can't find a datasheet for D207.

Thought I'd follow up on this thread. I tried to replace the buck regulator. I got a standby light, and a quick flash on the panel when pressing power but no back lights or picture.

Just decided to replace the main board. TV now works again!

I seem to have the same problem with a burnt IC206 on the main board of a UA75H6400. Did your screen have no standby light when it was dead? I’m trying to decided if I should stop blaming the power supply and replace the main board after reading your thread.

I'm keen to know how you sorted out the issue..!
Did you try replacing the chip?
