How to trouble shoot backlight issue Sharp LC46D62U

SOURCE: lcd sharp tv flashing green light

Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

if the tv is still under the manufactuer warranty i would definitly give them a call. If it is a Sharp tv I would call the 1-87-BESHARP. I would also try unplugging the tv for at least 2-3 minutes and seeing if the tv will reset itself. Usually what happens with these tv's when the light blinks it locks the tv as a security issue. If the unplug does not help it will more than likely need service to get this fixed for you. The call line hours are M-F 7am-7pm S-S 9-5 and they will be glad to help you from there.

I would check the System Cable that is linking the box to the TV. Then, press the small button called CLEAR in the front of the box. The button should be behind the flip cover on the front right below the PC input ports.
Let me know if this solution works.
