This is a tough one.
I guess I would start by unplugging the fuse panel connector and see if that stops the 5 amp fuse blowing.
I suspect you may have more fuses blown. Replacing the display and hoping the new one will not be damaged is pretty risky.
Not sure on yours but the 5 amp fuse may also protects the computer since it operates on low voltage.
