More information about the P1100, now the test pin 3. * Overview and voltage measurements of the 2.6V circuit, and also 1.3V. * The overview to a few cpu parts as also an voltage for the tuner. * And more.... The circuit 12v to 2.6v, and the circuit 2.6V to 1.3V are not fully displayed, only the most important information. Maybe I give later some more information about it. Have fun with this drawing, and good luck with solving the defect.
