Hi, I am hoping for some advice on my LG TV, I am fairly sure of the fault but need conformation before buying the part.
Faulty with an LG TV
I have an LG 42LS575T Smart LED TV.
The screen will work for a short time and then go blank, I have sound and I did the torch test and the picture is there and the TV appears to work correctly just cant see the picture. The LED's are off when the screen is blank.
After some research online I found the fault is the PSU which I presume has a built in LED converter as the only other boards in the TV are the mainboard and the Tcon board.
I checked the PSU Board and cant see any blown capacitors either.
Can anyone confirm if my diagnosis is correct.
