No Image on my LED TV when switched on

I am from India. We own a LG 42LW6500 3D LED TV.

When switched on our TV shows no image at all.

We opened the TV back cover and found that the backlights are working and the circuits are also not damaged. But still when I switch on there is no image in screen and couldn't check sound as we were not able to navigate.

The service guys reported that the TV Display is gone and you have to buy a new one as the warranty is over. Can you suggest me any other ways to figure out the issue. ?

And one question If the Backlights are working , does that fully mean the Screen is working properly, as you said in the video ????

Thanks in advance.

How did you determine that you have a backlight? what does your screen show when your set is off and when it is on? Have you checked your video connections? tried with a different input, i.e. Game console DVD player etc?

I removed my back cover and checked the small white lights glowing ....In a youtube video it is said that if the back lits are glowing then the problem is less.(https://www.youtube.com/watch?v=xUzCLgoS...) And I didn't not try any other inout as the opening screen Of LG logo itself is not coming.

Does the power light come on? Can you take a couple of pictures of the different boards and post them with your question? I am thinking that this could be a mainboard issue, which would be repairable. A broken LCD is almost impossible to find and is considered unrepairable.

The problem could be with your PCB. Recently , when i reported to LG Service - their answer was in negative as the PCB is unavailable. Later, i contacted a mechanic who repaired the PCB and is working absolutely fine as was earlier.

I also had this issue, It's the led backlight has gone bad. Company will ask to change the entire panel assembly , for huge amount of money. Or ask to buy a Annual maintenance contract. Still expensive. Simply go to AliExpress website, buy led backlight bars and replace them. Or u can also buy individual LEDs there, and reflow/hot air solder it yourself. The LG company is fraud. The service guy took ₹3500, but on aliexpress it costs only ₹2000. Thank you, Good Luck.
