In the measurements taken at the power supply, everything seems ok 5v 12v 20v. | On q1003 check the input and output voltages pin1 input 12v and pins 7 and 8 output must have 12 on the output if it is low check the gate voltage pin 2 of q1003 must be around 6v if not check the c1056 smd = 1uf may be leaking, an external 12v power supply can be used for more accurate diagnosis. | BRUSKE | |
