Help installing a 15" LCD to replace a broken A22m 14 i

[dbeltr1]

I acquired a 15" LCD (FRU 05K9581) to replace my broken 14" A22m (2628-PF1). However, I get a blank screen when connected to the a22m. My system works given that I tested it with an external monitor. What are my obstacles in terms of having the appropriate video cable (I have the 27L0663), inverter card (I have the FRU 12P3053), sub card (I have a FRU 08K3306 and a FRU 08K3261) Any suggestions on where I can begin to resolve this issue?
