Samsung UN55ES6100F No Video, But Has Power And Audio, Not Sure Yet If Graphics Can Be Seen With Flashlight.
Any Ideas As Yet?

LED problem, take the back off and post photos of the boards as detailed as you can.

Not a backlight issue either, I don't have access to set yet. Mainboard as a guess?

A lot of newer "no picture with backlight" faults are bad panels....

When it powers up, very dark blue display, you can tell it wants to do something, but no graphics. An associate, mentor commented 99% chance that it's a power supply issue.
Any thoughts?

A little confused, some of these ES series the T-Con is part of the panel? Can anyone confirm the following?

Troubleshooting T-Con/Panel can begin by measuring the operating voltage in from the
Main Board LVDS Cable at both sides of FP1.
-If the 12V supply appears on both sides of the fuse (with meter reference to chassis
ground), a correct supply is given and used by the T-Con.
-If the 12V only appears at the LVDS Cable End of the Fuse. The fuse is open and TCon/
Panel needs to be replaced. Sometime replacing a fuse will correct the failure,
however, before proceeding, check for any bulletins related to this condition.
-If the 12V does not appear on either end of the fuse, the LVDS Cable and Main Board feeds
need to be checked and LVDS Cable or Main board replaced. ALSO: check that the 12V
supply feed from the Power Supply to the Main board is present.

T-Con was the issue, replaced with new (TriState), success!
