does not switch on, does not charge, magsafe light off green-amber-off

2 years ago it has been replaced the logic board, after a few months it was off and is no longer running. now Apple does not want to replace the logic board with the extended warranty program ( i will go to my lawyer).

when I connect the magsafe first light is green, then orange and then goes out.

does not charge

does not turn on

no noise

the battery LED does not work

i tried another magsafe (from my macbook pro 13) but does not work

I tried disconnecting the battery cable for 5 min and then reconnected, the problem continues.

do you think it's a fuse problem? or a magsafe connector (internal circuit) problem?

or other kind of problem?

please help.
