Exactly. There are few, if any, 'stock faults' on classic computers. A 
blank screen (or whatever) can be caused by a lot of different things. 
Maybe some ware more likely than others, but you still have to do the 
tests to find out what has actually failed.

Another thing that a lot of people (not on this list, I hope :-)) don't 
realise is that there's no 'magic box' that you plug into a computer (or 
anything else) that tells you what's failed. Test equipemnt is essential, 
but in the end, _you_ have to interpret those readings to work out what 
the problem is.
