Hi,
Hoping you guys can come to my rescue here.
Firstly, let me apologise if my knowledge is not as thorough as you may be used to on this forum. I really know nothing about repairing, but I am reaching out in the aim of saving money on a repair and saving my family who are going crazy without a TV (2 young boys).
My LG 42LN575V has developed an issue. About 7 months ago, the backlight seemed to have failed. I could see the image if I shone a torch onto the screen. I sent it to my local repair shop and I think they charged me just over £100 to fix the issue. I say fix because the exact same issue has happened again (they only have a 3 month warranty on repairs).
I've removed the back and did some basic visual inspection to look for anything that looks damaged but I am at a loss.
After some light Googling, it could be the power board(?) which I can get a replacement of for £25. But I don't want to spend that on something which isn't the issue.
I have a very basic voltage tester which I was planning to use on the power to the LED strips to see if they are getting power.
I posted elsewhere about this issue and this response I got confused me further:
I tried to clarify the firmware point, but got no answer.
So here I am, with a busted TV and no money to put on serious repairs. Can you guys help shine on light on what could be wrong and can some noobie like me repair it?

These TVs have problems with the LED array, likely the TV repair shop only repaired the strips and not replaced the whole array as recommended by LG, also the firmware must be update when the repair is complete or the TV will fail.
