@imacpowpcintm the problem is going to be that we will need to see the boards etc. to provide answers :-) Remove the back cover and take some GOOD pictures of all of your boards. Post those with your Question. That way we can see waht you see. 7 blinks on this model is commonly caused by
Missing Vsus. ( Open or loose connection between connectors SC2(SN2)-P2. )
Abnormality of the scan circuit output, the 15V_F, Vad, and
Vscn circuit.
Open or loose Connection between the SC board and the SU/SD board (SC41, SC42, SC46)
Primary suspect is teh SU/SD board.
