thank you first for the upload!
You're welcome.
Incidentally on page 145 is the power-supply 'A1' but no circuit sheet. I must repair on the board itself not to swap out the board.
Well I repair on the board itself so I do that for more then 35years - maybe you have a real service manual and not the how to do swap a board plan.
What you're looking for is the CLIP, Component-Level Information Package, which includes the schematics. I've never seen one available for the 54720D, but perhaps someone else knows better.
