Default Re: Sony WM-D6C dc converter

OK so have done some more digging and taken some readings on Q601 and IC601.

In play BCE at Q601 are 5.3v, 6v, 6v

In play the pin voltages on IC601 are going from pin 1 to 16 are:
1.2v, 1.2v, 1.2v, 0.35v, 1.6v, 1.24v, 4.2v, 6v, 0.2v, 0v, 0.2v, 0v, 0.2v, 0v, 5.4v, 0v

the readings do not seem to correlate to the voltages in the service manual although reading other posts the manual could be wrong; however, I have to assume IC601 is faulty and will need to be changed?
