Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

Hi there.I have an lg led tv model 42LB5800 with no picture just sound. Also I can see the image with the torchlight. How can I fix it? thanks


The back light driver is bad. You could have lost the voltage from the power supply board to the led driver too. If you have a volt meter measure all the voltages on the power supply. The correct voltages are printed on the board next to the connector that goes to the rest of the TV. If they are all correct then the backlight driver is bad.
