Hi, here they are

It's right under L50, note the existing solder, I will try to clean it
off. What is it called, from the solder in the first picture left of
the L59, trace? Anyway under magnification that looks good. So would
this be the only place that needs the solder?

I don't know what you have there to the left of L50. It could be corrosion
or glue or something spilled on the board.
There are at least two tabs on that power jack that need to be resoldered.
One near the L50 and the other at the right end of the large silver area.

The third tab, near the edge of the board, may also need to be resoldered.

I would remove the solder on that tab and remove the connector from the
board, clean around each of the holes in the board and clean each solder
tab, replace the connector and solder.

But it would be a very good idea for you to practice on some old circuit
boards first.
You should be able to find an old computer or tv or ... electronic device
sitting by the trash cans.
Or go by a repair shop and ask if they have some trash boards that they
will give you so you can practice soldering.

You might even get them to give you some lessons or at least let you watch.
