I have problem with a HP G62 with PM_A_HPC_S MV_MB_V1

- the laptop first time power up , fan spinning but no image , give a little hot air at 2001 north, but now power up and down in 2 seconds, if i repeat to turn on laptop , north begin to be hot.
- remove northbridge , same problem , turn of in 2 seconds,
- replace northgridge with another, same problem, gets hot if still trying to turn on .
- the processor is very hot, like north
- turn on without processor , same result.

Any help ?

Usually the replacement of 216-0752001 is the solution.
You can also check the gpu if it is the 216-0774009
