Chosen Solution

My G5 can’t boot and the led 3 in logic board can’t light,so I think maybe there has some problem with my logic board,and i have another working G5 model A1058 17 inch,i open it and found the logic board is the same,but i not sure,so my question is can i put the 17 inch the logic board replace the 20 inch logicboard,thanks helping me

The 20" A1076 uses a 820-1747 board whereas the A1058 uses a 820-1540 board. The boards are not identical. Compare the connectors i.e. J7600 etc which is not located where you would expect it etc. It is a different board. The Mac Mini uses a different technology altogether and it will not connect to your display etc.

These logic boards are not interchangeable.
