Could be that a conductor is damaged/badly terminated

I don't have the standards to had, but saw them somewhere

found this brief guide tho.
http://www.hometoys.com/htinews/feb00/articles/totolo/totolo.htm
'Whenever cable bends are required, maintain a minimum turning radius of 4
times the cable's outside diameter (for CAT5, approximately 2.5 cm; and for
RG-6 and fibre, approximately 3 cm.)'

I'm sure someone on this list will have the full standard ;-)

It sounds increasingly like you are going to need that 'proper' tester
though :-(

Go back to basics - and "divide and conquer".

Buy two new sockets and a proper punch down tool. Disconnect existing
wall socket and punch down new socket on a bad cable. Test. If it
doesn't work, disconnect at patch panel end and punch down second
socket. Test. If that doesn't work, then check that you have the same
cable at each end (perhaps using a battery and bulb -   or more
sophisticated test gear if you have it. Connect battery across a pair
at socket end - ideally direct to the wire - and probe with bulb, but
ensure all kit is disconnected from patch panel first).

At the end of the day, it's only wire and sockets - it's no more
complicated than wiring phone extensions. FWIW I'd put my money on
the cables either not being punched down correctly, or being mis-
labelled (which sounds like a complete nightmare with so many
points). (One final outside possibility is that the cables have been
fractured through rough handling, but it's pretty hard to do.)
