ONE FINAL PLEA . . . . .
Carpenter . . . . ehhhhhhhh . . . .
Assuming that you have seen INNNNNNNNNNUMMMMMMMMMERABLE nails on the worksite and assuming that if to see one of them sticking out of a tire on your vehicle . . . . now I ask you . . .would it be receiving the same lackadaisical / languid / irresponsive chain of thought such as this solder drop / splash is receiving ?
POINTS OF PHOTO REFERENCING ARE . . . . . .

Looks like that Sony unit has given you
YEARS of service and WILL potentially give you a like further amount . . . . in spades . . . . . if considered.
Considering the due diligence given by Sony final Quality Control inspections I can't see that even
starting to get by that inspection.
Since you were soldering in the line cord and remembering the physical plane that the radio was positioned in . . . .what are the chances of your unsoldering and resoldering in, could have had that excess blob roll down and come to rest across those two terminals.
The particulate solder trail
is originating at the top of the board and the final roundness of he blob is indicative of there never being anything but a cooled blob coming to rest in its place.
As far as the soldered connections, that it had come to rest across . . .the white overlay of silk screening hides the reality that FOUR separate connections exist at the very bottom of the board.
Two are being as a transformer winding connected to the left.
Then two more to the right are connected to a separate transformer winding.
4 separate wires finally route away on the back side of this minor PCB to the main chassis.
This 1-435-503-11 Power Transformer . . . . . .
No
Longer Available . . . . but if it was . . . .Sony last listed $55 for it.
ITS REFERENCING . . .per its SCHEMATIC . . . .
All it would take is a re examination and even a pair of neeedle nose to grab the blob and rotate free and then inspect to see that no minor bridging solder residue is still present . . . . which I don't expect, due to the solidity of the blob after cool down in its final rolling down that distance. . . . but it DID leave a hot trail of solder residue on insignificant board surfacing its way down.
Thassssssit . . . . .
