Diodes across the coils can cause driver transistors to short

Quoted from onlydjz:

Oouch...I have found this topic. Pic shows that the first pair of TIP caused the burnt surface, the second pair is in the board and locked on coils again.

You will have to grind or chisel out all of that burnt PCB BEFORE replacing the TIPs as the charcoal will conduct and prevent the transistors from operating correctly. Actually, if you leave it, they are likely to lock on and bad things will continue to happen.
