Default Re: LG 43UK6300 - Audio & Backlight, but no Video

OK did some more looking around and seems like a burnt Transistor. I wasn't that pronounced, as in the original pics i posted, but i figured i try the oven bake and it made it more obvious. The behavior is the same as before the bake in.

I have attached some closeup pics (before over bake as seen in Pic #2 in original post).

How would i go about finding what the transistor and perhaps replace it. The two resistors above it when measured are around 70 Ohm each although there is some discoloration on one of them perhaps from the burnt transistor.

The part # for this mother board is EBU64688103 and wondering if i use EBU64688102, will that work, or would that be a different firmware ?

The complete model # for this TV is 43UK6300BUB.
