But you as the TV tech would know what the service manual has to say about how the light works. Here's a handy link where a TV tech shares. Notice they didn't really fix it? More of a band aid.

As you are the TV tech, you get the service manual and use your prior works to lean on. Today we can see if anything pops up on the web as well.
Hi,
My 42LG5020 HD LCD tv backlight appears to have just broken. Do these tv's have a backlight that can be replaced?
I am reading that inverters are a common fault on these tv's. However, all the stories report that they loose the image but they can still hear sound.
My problem is the tv went dark, like somebody had turned the backlight off, turned the brightness down and the contrast all the way up. I have a picture, its just dark, red and rubbish. The sound is un-effected.
Has anybody experienced this problem or does anybody have any advice?
Kind regards,
Lars
