Set turns on normally, backlight stays on, after about 20secs or so thin vertical colored lines appear on the left side of screen.
First i tried disconnecting the lvds ribbon cables one side at a time to see if i would at least have half a picture, i got nothing.
Hooked both back up and started probing voltages on both ribbon cables, got nothing, disconnected one and got all the main voltages/signals on both ( supply - 3.2v, 26.2v and 1.8v for signals).
So started checking for shorts on this side - right driver board, mainly caps, nothing found, so decided to hook it back up and try the reverse with the left driver board and to my surprise the voltages all came up nice and steady, so hooked both back up, voltages all gone.
So went checking further into both driver boards and found these packs (see pics below) all reading short across their pins on both boards, my question is are these the famous diode packs or resistor packs, if they are diode packs, how should these normally read/test.
only d17 on right side board and d47 on left side board shorts on half of the pins, all the other packs on both sides read dead short/continuity across all pins, there are 4 driver boards, the two boards with the packs are the ones on the outer ends, i disconnected the other inner boards and still had the shorted readings, any ideas or help is appreciated as always.
Also if i disconnect the outer driver boards one at a time i get a white segment, one side is all white,no lines (right side) and the left side is same white segment but with thin colored lines see last pic.
