Hi Folks,
Just picked up this TV and the symptoms are non-responsive. It turns on, you can see the LG logo, when you click the menu button, you can tell that the upper left corner is changing but the LOGO overlay is on the screen.
The weirdest thing ever is if I power it up with the 2 ribbon cables form TCON to Panel disconnected the LOGO is still visible / DIM. It's like the logo is stuck on the panel (in color so not burnt in)
When I disconnect one of the ribbon cables, one side goes black and the other side has logo but the upper strip is white just like when you activate a menu. When I disconnect the other ribbon cable, the other side goes white but logo overlay is still on that side! very odd!
Labeled voltages seem to check out.
20 V and 3.5 from power board to Main card are at 20.32 V and 3.38 V
12 V to TCON is 12.03V
I see various voltages on the boards - not labeled so I don't know variance over nominal
