Hello all I purchased this on ebay and the seller said the logic board was bad turns on but will not boot, I do get a green light then amber on the charger but no power. The inside of this is spotless no dust or corrosion that I can find anywhere (under high magnification) So I purchased a new logic board installed it and now I have no lights on the charger and no power. Any Idea's ?? ..... I'm thinking DC in board may be bad ? Does anyone know of a video that show's where to test for all the power rails on this board ??

Thanks for any input on this.
