Step 2Disassembly
So once its all apart, start off by locating where the power inputs are. Something that I like to do is to take a picture of the board (or scan), and put it into photoshop and color in the traces according to their use. It's a helpful tip that I like doing, because sometimes when your cutting up a board, you will forget what things went where and things just get crazy.
Once you've found the power connections, I would test to see what voltage the unit runs one. Most commonly it's going to be 5 volts, but just check to make sure. In my case the wall adapter was ouputing 13 volts, but there was a 5 volt regulating circuit on the controller PCB.
The next thing you want to check on, is there or not the player buttons have a common connection. Most of the time they will use ground as the common, but I've seen others. In my case it was ground, which works out perfectly because the TLC5940 outputs only grounded signals to achieve PWM.
