Sony KD-55XG8796 No power

[matyka]

I have been given a Sony KD-55XG8796 with no power no lights. I have done some measurements and I found diode SB260 shorted D950A position on the board.
I have replaced with SR260 and TV came up to life.

Nice work, sometimes it's something pretty simple, that's why I ALWAYS check those things first: https://www.youtube.com/watch?v=AynXoLjYrKc

Nice story from my past.... About 30 years ago. A friend of mine had a cassette deck which was low on one channel. He couldn't figure it out. He had signal tracers and oscilloscopes on the job and he'd even replaced a transistor and the dolby IC on the bad channel but the fault remained. As soon as he let me hear it going, I wet my finger and wiped the play head. Fault gone. He was pleased and angry at the same time lol.
