See attachments.
I've removed the Q743 and Q751 D10PFT06 on one model, FU9024N on the other. Best I can tell they may all be bad.
The Q739, Q740 and Q759, Q760 C5707 seem to be good on one monitor and bad on the other. The fuse is bad on one monitor. I've checked R765 and C765 that control the frequency of the oscillator circuit in IC751. Best I can tell they are within tolerances.
Waiting for parts and time and knowledge.
