SHARP - LC50LB370U
I have done my research but have come to a dead end.
All started like 6 months ago, my Sharp tv got a black line down the middle of the screen. The line was like 1/3 of the screen and in the middle third. It wasn't a sharp line, it was like a hazy black line that made the picture dim. Like you couldn't barely see it, unless the screen was like a solid white color.
That went on for like 6 months or so then all of a sudden the tv would power on, but no picture would be seen. I thought about just junking it then. Bought a new set. But once I started researching, this seems fixable, hopefully with a little help. I first did a factory reset type deal. And I actually got it to show the input screen for maybe 5 seconds then it went out again. I then found out about the flashlight test, and sure enough the picture is there with the flashlight test. I haven't tried sound yet. So then I saw it could be the power supply board. I was hoping to take the back of the tv panel off and see a capacitor bulging, but they all look fine. So that is where I am stuck... any ideas. Here are the picture I took.
Thanks a lot!
