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.
