The LG 47LV3700 I'm fixing seems to power on but I have no backlight, no picture. Power supply has 3.3, 12v, 24v and 36v at the LED. I used a LED tester and seemed to get the LED's to light up but not sure if each strip is working. When I try to power the set, the red standby light on the front of the TV flashes 3 times and then turns blue. Not sure how to proceed.
