If by reason of absence, death, sickness, or other disability, the judge before whom the child has been tried is unable to perform the duties to be performed by the court after a verdict or finding of guilt, any other judge sitting in or assigned to the court may perform those duties; but if such other judge is satisfied that those duties cannot be performed because of not presiding at the trial, such judge may grant a new trial.
