Seriously, sometimes the choice is to either take a
chance without
any outside information, or to leave it as a non-functioning display
piece. That's something for which I have no use. I have blown or burnt
stuff up that I really wanted. It's the occasional price of making
things work.
Yes, but it's very rare for an electronic failure to do cosmetic damage
to the machine. So even if you do wipe out some irreplacable part during
testing, you _still_ have the machine as a 'non-functioning display
piece'.
This is not a reason for being careless, but you really have very little
to lose by carefully trying to get things going.
