Question about Televison & Video
I found that Shorted (K2647) MOSFET in primary section of SMPS resistors 1 ohm and 10 ohms open/burn. i try to replace then check all the primary components. all are ok but still no oscilation. i check linear side of the power supply i found 300 volts DC in Filter capacitor.
There should be a small valued cap in the primary side (22ufd?) at 250V. Check that. Also, look for other small caps int he range of 2.2ufd with 200V ratings in the same general area.
