If you wish, we can tell you a normal procedure. However, that might not help you because even a small mistake can lead to many bucks. You need to have proper diagrams in order to fix this. No one would be able to offer you all diagrams except the service manual for your model.
There are so many sites who would claim to offer schematics and service manuals, However either those are totally Fake or sometimes too costly.
The link for the manual ( Free ) would be :-
I hope you would be able to fix it.
Any further help, let me know.
