My Blu ray player Sony BD-370 recently blew its power supply board. The service manual of the Sony BD-370 does not include the schematics of the smps power supply board and I could not find a circuit diagram searching the web.
The power board number is APS-257 and manufacturer part number is 1-474-194-11.
On checking the board, the switching MOSFET 3N62K3 was found to be damaged. In addition, 3 resistors were also burnt (please see attached images). I am now stuck because I do not know the values of these resistors to replace it. Spent a lot of time searching the web but could not find the circuit diagram or a picture that was clear enough to show the values of these resistors.
The resistor reference numbers on the board are R106, R107 and R113. Any help finding the values of these resistors is appreciated.
