Removal I can help with. Finding the RCA jack is a little tougher. This part is on you.
Does the circuit board remove from that back plate, where the RCA jack pokes through?
It would be nice to get it out of the way.
The RCA jack does unsolder from the bottom of the circuit board.
1) Use a low Wattage soldering iron. Put a soldering GUN aside.
TOO much heat.
20 Watt soldering iron.
2) Soldering stand, or at least a damp sponge nearby to constantly clean the soldering iron tip.
The soldering iron tip NEEDS to be well tinned, and clean.
3) No.2 chisel tip. It will make your life SO much easier.
[Soldering tip is taken down to the bare copper. Then heat soldering iron. Do not leave plugged in too long. Use Rosin core solder, and I would recommend .030 in size.
Soldering iron tip hot, touch the rosin core solder, and give a light coat of solder. -> Tinning ]
Removing that RCA jack to me, is just like removing a DC Power Jack, from a laptop motherboard.
First thing you want to do, is remove as much solder as possible, from each solder joint, on the bottom of the circuit board.
I use Desoldering Braid. (Solder Wick)http://www.radioshack.com/product/index.jsp?productId=12580047&filterName=Type&filterValue=Desoldering
Unroll the wick about 6 inches.
Lay about 1/2 inch of wick across the solder joint. (Solder connection on bottom of circuit board)
Put the soldering iron tip on Top of the wick, and on top of the solder joint.
When the wick starts to absorb the melted solder, remove the wick.
Cut off the solder soaked wick part, so you will have a new wick surface to operate with.
Keep going around the solder joint, until most of the solder joint is removed. You will NOT remove all solder. You are JUST trying to remove the majority.
Perform for all solder joints (Connections) on the bottom of the circuit board, for those RCA jack leads.
Remove solder from one lead -> STOP
Allow the circuit board to cool down.
Then continue on.
Circuit board on it's side on the workbench, hold the insulated part of the RCA jack with one hand.
You want to rest your hand on part of the circuit board, (If possible), and use the heel of your hand as a fulcrum.
Fingers constantly applying pressure to the jack, pulling jack away from circuit board.
Heat one of the solder connections up on the bottom of the circuit board. Applying pressure with your fingers, see if this one lead will start to come out of the circuit board.
It will only come out so far, as the other leads of the RCA jack are still holding it in.
The method is to heat one solder connection, try to pull the lead out of the circuit board a little, then go to the nearest lead; and heat it up.
(Heat it up = Melt the solder)
Keep pulling the leads out a little at a time, and going from lead to lead, until they all come out of the circuit board.
What look to be very flat thin copper wires, on the bottom of the circuit board, are actually Circuit Traces. Also known as Signal Traces.
IF, you heat the solder joint (Connection), too long, you stand the chance of ruining the circuit board. This = No.
You can lift the circuit trace right off of the motherboard, using too much heat.
You can burn the circuit trace 'hole', and this will make it so it will NOT accept solder again. (You can't tin it )
GO SLOW. You have as MUCH time as you need.
Suggest melt one solder joint a little, pull on on it's lead, then allow the circuit board to cool down some.
Then go to the nearest lead, heat it's solder joint, pull up; then let the circuit board cool all the way down.
You get the picture
[Leads are the 'stiff wires' coming down from the RCA jack.
Circuit trace 'hole', is the hole where the lead goes through in the circuit board ]
When the damaged RCA jack is removed:
There will be residue left behind on the circuit board 'hole'. This needs to be properly cleaned.
I use Isopropyl Alcohol, and an old toothbrush.
Isopropyl alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present.
Yeah, I know. A disclaimer. I just want to make sure you do not get hurt.
Means circuit board well away from the hot soldering iron, when cleaning.

There may also be a thin coat of solder over the circuit trace holes, left behind.
DO NOT worry about it/them. Leave alone.
When you go to install the new RCA jack, you will cut the leads until they are about 1 inch long, if not already that length.
Bend the leads so you can try a trial fit, and make sure each lead is going towards it's circuit trace hole.
Leads of the RCA jack pushing against (Lightly), the circuit trace hole, and the thin solder 'skin'.
When you heat the circuit trace hole from the bottom of the circuit board, the solder 'skin' will instantly melt, and allow the RCA jack lead to poke through.
Don't know if you used to solder back in the day, but solder has changed now. It is 'green', and no longer contains lead.
Makes it a @$#@^ if you are soldering with it the first time.
Suggest practice on soldering wires together, and perhaps an old circuit board.
The solder joints you make MUST be clean and bright. They should look like a 'Hershey's Kiss' when properly done.
IF, you make a bad solder joint, it is a Cold Solder Joint.
This = No.
You'll be pulling your hair out trying to figure out what is wrong, when it is just a cold solder joint.
