Doesn’t look great at all…..


After the initial cleaning, it was quite obvious that some of the circuit tracks and pads were already gone/missing by the poor previous work….



Also, the leakage from the original capacitors were left too long that it dissolved so many tracks.


At this point, I had to stop working on this board for a while and get to my NSX.


There were so many damages to the board and even missing the trace of original track/pad that without a reference circuit board, I couldn’t go any further with this board.


Took out the CCU and removed the circuit board from my NSX.


It will be used for the reference.

R37 had to be removed for now as it was replaced by someone in a different size and the soldering
was just terrible.


Also, I had to double check that the resistor itself was not damaged as well as at the correct resistance.


I hope Q9 is still operating although it looked liked it was abused with excessive heat by poor soldering method.

The exploded C44 done a great job in damaging the circuit tracks and pads.



It dissolved the circuit at DM11 but I managed to recover it.

The leakage from C10 and C14 were just amazing…
