There are 3 positive and 3 negative rail caps. Typically, all 3 negative caps are near the transformer. For the positive rail, 2 are in that area and the other is in the blown location.
If only that one failed, it may have simply failed due to age. I'm assuming that the vias are intact for the ones you replaced so the blown one wasn't pulling the entire load.
I'd suggest that you carefully look for broken solder connections on the large transistors on the driver board.

I’ll replace the blown cap and checked the driver board tomorrow, will keep you posted. The caps I changed was over two months I don’t think I damage any vias during that process as I had checked for continuity on top layer and bottom layer of the rail circuit trace.
@nigelwright7557 I’ll remove the cap covering and inspect the output caps and test them also with my esr meter.
