Hi, I just joined this forum looking for answers about my MB4210, and clearly they've got big issues. My own was cutting out a lot recently, so I installed a second fan in it exhausting out the side of the amp, and that reduced the amount of cutting out, but it wasn't perfect. However, the cure was much simpler. Putting just about any household fan on any setting directly behind the amp blowing at the built-in fan massively reduces the internal temperature and completely stops the cutting out. At work I sell thermometers with remote sensors, so it was easy to see just how much difference inside the amp this really makes. my second internal fan dropped the temp 2 degrees, the fan at the back dropped it by 13 degrees C. So simple. Bloody ridiculous, but easy to get around.
