How do I fix dark screen but can faintly see picture when I hold light

I have LG 47LN5200-UB, has been working fine but two nights ago went to turn it on and screen is black. I can see a Faint picture if I hold a flash light up to the screen.

I have tried unplugging it, holding the power button for 10 seconds and plugging it back in. I tried switching picture settings to vivid. But did not help. Sound works fine.

What else can I try.

Also when I power on the TV, a light flashes across the screen then goes black. With just a really faint tint of picture or menu on the screen. Can only be seen when you're holding a flash light up to the screen. Sound works perfectly to what ever input you select.

It will be a tcon or backlight issue, Look for someone local to you to repair it or if you feel you have the confidence do it yourself with some help from us.

If you let it warm up a bit then the picture will eventually turn out clear.

It may work. I had a similar problem, but not the exact one

I would put money on the backlight being gone. The flashing light on startup makes me think the transfomer. I would look to start with replacing that first.
