From my reading, this LG looks like so manty others, with the slightly visible logo at power on.
I'm pretty sure the metal back is coming off so I can replace ailing backlights.
I thought I'd go ahead and post up, since this model didn't search here.
Here's the 20 pin voltages:
GND
11.8
11.8
GND
23.8
GND

3.3
Evens
GND
23.9
11.8

3.4

3.3
The big cap is 395 VDC.
There are 2 pairs of LED leads at P801.
With P801 connected:
Pin 7 LED+ 207
Pin 5 LED- 26.8
Pin 3 LED+ 138
Pin 1 LED- 18.8
With P801 disconnected:
Pin 7 LED+ 90
Pin 5 LED- 0
Pin 3 LED+ 90
Pin 1 LED- 0
The voltages don't spike at P801 when powered on, and connected.
I guess we'll see what needs replacing after I get to the strips.
Or are those voltages pointing to something else?
