I swapped over my HDMI cables, too be honest i didn't even know if it would make a difference or not. com, as the biggest online shopping guide website. LCD or Liquid Crystal Display is a flat electronic display which is very commonly used in digital watches, calculators, laptops, televisions etc. First when I turn on the TV, I see the backlights power on (but very dimly), then the backlights turn off. Thanks for the response mate! I was wondering why common LCD's do not reflect light (but you cleared that up). Without the backlight, a screen will not display a picture, and the inverter board should be replaced to restore normal operation to your TV.
