first you need to look at the displays themselves before you go nuts attacking the MDB chips. Disconnect the two suspect displays and power up. the resistor should not get hot. if it does, disconnect all the displays and power up. still hot? then it's a chip. If not hot, it's a display glass problem. Connect displays one at a time and power up until you find the display that is causing the problem. I find the issue usually is display glass related.
