Try unplugging and replugging the TV to cause reboot. After reboot do a scan for digital channels.

3 year old 42in LG LCD TV scrren went blank


You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.
