what I know, what I have been able to do to this point...
my LC-60LE810UN basically plays blind, it has the one fast one slow blink, I am able to boot the TV up in test mode with the -neg vol ^channel up and power buttons
once in test, I can see the menu with a flashlight to the face of the screen, at no point does the LED's that back light come on, they do not blink, they do nothing, the TV senses connection on any of the inputs ( HDMI port ) and will play a DVD
I have lightly cleaned, removed and inspected both the power board and main board without seeing any obvious signs of failure, I have inspected the " T " board and that looks good too
I have a fluke, on the power board I have tested the diodes in series and they all seem to check out ok acting normal from what I can tell without schematics and the values
same for the caps... they all look fine on the power board without any signs of imploding or pregnancy
I have poked around at voltages, tested the 120AC and a few other sections of the AC side of the power board, moving to the DC side of it, I got the usual 12v and 5v and 3.3 in certain locations
I have a blinking light on the main board, to the right of the center heat sync, its blinks on and off consistently
also the one place I did test voltages, where the problem cound be was at the LED DRIVE + L1 & L2 connections, and experienced really low values from 0.007v to maybe 0.018v
from what I have read, this is the LED power section, that fires up the backlighting, and should output somewhere around 120v to 150v to be in working order ?
does anyone have any suggestions? thanks for your time & reading all this
