I believe that you are referring to the small yellow ceramic capacitors on the amplifier boards that tend to short out. Below I have pasted a link to a forum thread that contains the information you are looking for as well as some great pictures of what you should see. The driver IC that you are referring to I am guessing is the STA575 amplifier chips which are located on the amplifier boards attached to heat sinks. One board has 2 of them the other has 3.
