C50D no voltage on COIL

[gcomputers]

I m working with this satellite c50d-a-133.
First problem is not charge , i checked fist 19v is ok , on fuse battery have 3v ok, 3.3v , 5v ok.
So i flashed bios and OK charge power up but no display ..................
now no display , no fan activity vo voltage on fan pins , cpu no voltage on coil and THIS COIL JP8010 OR JP8011 IS SHORTED WITH ground.

i don t have schematic , any experience or advice pls .

Re: C50D no voltage on COIL

anybody have this schematic.
the mosfet near to coil (on the picture) pin 5678 have 19v , pin 1234 0v i think maybe this is the problem but i don t have schematic to identify the model of mosfet?

Re: C50D no voltage on COIL

If don t have voltage on cpu coil and no fan activity is IC problem or maybe any mosfet burned ?
My question is about your experience with same problem.

it seems the amd cpu is shortes,i checked on a workin MB and yhe inpedance to
ground is aprox 20ohms,in my expirience this lind of chips tend to overheat and short
