Hi everyone,
A friend of mine gave me his TV after it stopped working, he gave up trying to fix it after it caused him so much trouble throughout the years (flickering image, sometimes no backlight, etc.). The latest problem was a weird noise and no power.
I opened the TV and saw the power supply board with a transformer burnt. Here's the pictures.
Notice the green component has slightly darker color on the board, could it be an issue with that also? Would it be safe to replace the transformer? Anything to look for that might have caused this and that should also be replaced?
Thank you
FYI: for the previous problems, I replaced 2 backlight inverters

I also cut the jumper JP854 like in this video https://www.youtube.com/watch?v=i-jQZ-TQdgU
It never fixed the issue.
