D12, D13, Q3, Q101 (PS-543 board) : Mount the part so as to be perpendicular to the board surface. Cover Q3 and Q101 with the AC heat conductive sheet. Refer to Section 2-10-2 �Removing/Installing the PS-543/544 Boards� for details. n If the sheet has breaks or cracks, be sure to replace it with a new one. AC heat conductive sheet : Sony P/N 3-615-731-0X Installing AC heat conductive sheet (1) Fold the AC heat conductive sheet into half. Fit the two projections on the AC shield chassis into the holes on the AC heat conductive sheet. (2) Affix the AC insulating sheet to the AC shield chassis with a new double-sided tape.
