A quick question for those who have seen lots of transistor failures.

I replaced an MPS-A06 on a video board I was repairing.  When i powered
up the board, three minutes later, the transistor blew apart.  
(The board does a degauss first.)

Basicly, is this a bad part or not?  I have never seen a failure that had
the transistor blow.  (I've done it to some diodes, and capacitors.)

The tranisitor I replaced controls a part of a final push/pull transistors
that had one go out.  (I've checked everything around/connected to it and
they checkout as good.)  The the specifice transistor and its PNP mirror
are the most commonly blown devices for the board I am working at.
(Sounded like finding the bad capacitor with a current source... POW!)
