late post wow…sry. Final Resoulution: I replaced the main board and it worked like a charm. Reason for this: Once tearing the set apart and getting the backlights to magically come on and working…..voltages were fine going to leds and main board. once plugging in the main board, voltages would drop to leds and main board voltages were fine up to the lvds out to tcon. There wasnt a schematic i had so i just used the printed readings at vdd and 12v in on the tcon from the main board. all voltages were present and correct from power supply to main, and somehow got lost from main to tcon. So, i decided to give that board replacement a go and it worked in this case. Hope this helps, and thank you oldturkey and others that were coaching.
