Its the same problem as suggested..
But, i'm facing some trouble to mesure the resistor 837 ! with the multimeter i'm not receiving any values from any of the other resistors... i presume that the problem should me in this resistor, rigth? Or shoul I look to CPU?
(i did the path until the keys, and the flat wire, and its all okay.
