Re: LG 42LN575V backlight issue.

Hi

trying to fix 42LN575s with no backlight but still can see picture with flashlight.

Here are my voltage testing:

When led unplugged (1 led+ 2 led- 3 led+ 4 led-):

1 220-235V
2 0V
3 0V
4 0V

When led plugged:

1 220-235V
2 140-160V
3 130–150V
4 95-115V

Cap 335V

Would that still looks like bad led strip? even if pin 1 voltage is more than specs?

thanks
