47LC7DF, Green light comes on, blinks with remote
When you say that you have replaced the main board i assume you mean the power board? If the green light comes on and blinks when the remote is touched it was never a issue with the mainboard, if it was you wouldnt have any signs of power. In most lcd tvs you have the main board which is normally the power board, the signal board which recieves signal and hold settings of the tv which can be all in one, the other is the inverter board, which scrambles the signal to what you see on the screen, and next we have the back light which lights the screen so you can see the picture, sometimes in certain models as i have learned you can have power/inverter boards which means the inverter and power are all on the same board, in your case i pressume the inverter board is seperate board and probably the issue you need to address, you can buy these online probably the same place you got your new mainboard from. Hope this helps pls post bach what happens.

This is usually caused by dirt trapped between the lcd filter layers and appears when the screen is pressed, pressing the layers togehter producing an internal dust smear..This can only be removed by stripping the lcd down and cleaning the filter layers
