If FET 2SK2671 has found damaged,
check all these components. It will be best to replace these components, even
if they checked fine. C807, C842, R819,
D837,838,839 & 840 and components marked in rectangles. It will be best to use a good quality analogue
meter like [Sanwa YX360TRF or PHILIPS PM2506] to measure the resistance and voltage levels
to SMPS circuits. Each time, before
measuring any voltage, discharge the main reservoir capacitor. Otherwise, the stored current in it might
destroy the measuring equipment. If the
FET is found shorted, check all the other components individually. It is a must. The Power Control Module [DPM001T1A] should also be checked.
