Another (quicker, easier) way if you're crap at soldering or don't own a soldering iron is to use a lead pencil. I used an IKEA pencil (available free from every IKEA store)
TP1 TP2 TP3 are located through a small rectangle hole on the underside of the unit. And as an example the soldered bits will look something like this:
( ) ( ) (O)
The third one having a blob of solder on it. Your stereo may have a blob on a different connection.
Use your pencil, and draw circles (so the pencil-lead makes the connection) on the connections that do not have a blob of solder on.
You need the connections to be bridged like this:
(O) (O) (O)
It is important that you do not let TP1 connect to TP2, or TP2 connect to TP3. If they touch, then this trick doesn't work. So once you've drawn a good connection with your pencil, blow away any excess pencil-lead dust, and use a small flathead screwdriver to GENTLY scrape/remove any stray pencil lead that may be joining TP1 to TP2, and likewise between TP2 & TP3.
Plug in and happy days! :)
