My favorite cheap way is the desoldering iron Radio Shack sells for about 10
bucks, it's one of the few useful things you can still buy there.

get some old tv coax 75ohm cable, cut off the outer plastic insulation,
(carefully, so you dont cut the copper braiding), then gently peel back
the copper braiding exposing the plastic centre with 1 central wire.
cut this plastic off leaving the braiding clear. apply this to your
heated solder joints when uysing your iron and it should absorb the
solder. coating it in fluxite (solder paste) helps.

Thank you.
There are 2 lines of number on the chip somwhat like this
LA7830
2C 4

Pardon my ignorance.
Should I completely remove the old solder before resoldering?


That's the vertical IC. You don't need to remove the old solder. It
sounds like you may cause more harm than good by trying. You only
need to remove the old solder in cases of extreme heat damage which
crystallizes the old solder. In this case just applying a little new
solder will work fine.
