I'd check and see if t-con has an AS15 chip on it... common fault.

Re: Le32m86bd

Good, near the top right of board and AS15 there are a set of points marked VGAMA1 thru VGAMA22, see them? With the board installed and TV showing picture, measure voltage on each point with respect to ground. Report each reading, along with VGAMA name.

Definitely bad. Replace AS15 chip or t-con board and it should be fixed.
