Set your multimeter to the diode test mode. Put the black (negative) probe to pin 2 of chip U15.
Put the red (positive probe) to the listed pins and specify the results:
  • Pin 4 of chip IC1 (see picture below).
  • Pin 4 of chip IC2 (see picture below).
  • Pin 4 of chip U12.
  • Pin 4 of chip U501.
  • Pin 4 of chip U502.
  • Pin 4 of chip U505.
  • Pin 4 of chip U506.

- Are you sure the voltage is only on pin 5 of this chip?
- Measure the resistances to ground on all pins of this chip.
