following the voltage path I should have the 12v on the vin of IC101 but nothing arrives there
Hi Azgael, yes, drain of Q102 and VI of IC101 must show the same voltage.
But 5 V at drain of Q101 is strange. If the controller doesn't work the gate of Q101 is pulled to 50 % of "+12V", so here around 6 V. In this state drain of Q101 should have something close to 0 V and not 5V. I would check the reason for this.
