Started to rebuild so many damaged circuit tracks and pads.
After more than 10 hours, finally I managed to get to the point where I was happy to power up the board for the first time after receiving it.
At the end, I used 8 x hard wires, 4 x jumper wires for the rebuilt process, lots and lots of soldering bridges to reinforce the circuit pads against the noise and ripple.
I have worked on many CCU boards but this one made the new record for the amount of extra parts required.
Two hard wires and soldering bridges used around C44 area.
Four hard wires used around C11 area.
One hard wire and soldering bridges around C10 C14 area.
Four jumper wires and one hard wire at the back of the circuit board.
