3, using the oscilloscope test TPSC1 wave type, wave type found abnormal (waveform as shown in figure, for the convenience of the difference between the oscilloscope timeline 1 ms/div), check IC6511 peripheral, found that there are about 5 k bootstrap capacitance C6511 leakage resistance, has been damaged. Basic returned to normal after replacing C6511 images. BSgservice manual download site
