Potentiometer & Soldering Steps??

Hey. My rec gain knob is busted. I believe it is my potentiometer. I opened up the mpc1000 casing, and noticed the board the pot is connected to.
I've never done anything like this so if someone can give me some steps I'd appreciate it.

First of all...how do you get those 2 white connector strips and 1 blue strip off? I haven't tried the blue one. But I tried pulling, lifting, pinching etc the white ones and they won't come off. I've used quite a bit of force.

Then I unscrew the board. And I've never unsoldered something. What, do I flip the board over, and apply the solderer directly to the board to heat up the lead already put down? Then pull out the old pot? Put the old pot in, and solder that down?

A bit of information in any or all of these steps would be greatly appreciated!

Thanks.

hey - for the cables, they should slide out horizontally IF that's the right end of the cable. check the other end. one end is actually soldered into the board itself - the other has a connector (phr-X connector) which slides into a receiver. this is what you gotta find.

the blue strip has a little plastic lock (looks like a little ridge) that you must push left a little with your fingertips. this releases the pressure keeping the ribbon in place.

flip the board over, let the iron heat up, make sure you have your solder sucker ready.



apply the hot iron to the solder points and use the sucker to draw the solder from the point with a quick SHLUP. repeat as necessary. just use this to get as much out as possible. then, there will be a tiny bit left on every joint. run the iron from joint to joint while pulling from the other side. work it out gradually.

then put in your new pot and turn it back over. make sure the new pot is all the way in, safely. touch your iron to the new solder points and tap it with solder. bump in just a tiny little bit of solder - enough that it holds and a contact is made. don't get too gloppy. if you accidentally "combine" solder points, don't panic - just apply the iron and use the sucker to get rid of the in between.
