I have a flatscreen monitor whose (separate) PSU has died and needs
replacing. It's a 12V 3A unit, and as luck would have it I happen to have
a similar one going spare from a netbook which I no longer have.
Q1: is there any reason why this putative PSU wouldn't be fit for purpose -
ie is there any other characteristic other than 12V/3A that I need to
consider here?
Q2: Assuming we've made it past Q1 - unfortunately the (LV) plug which
connects to the monitor is slightly but crucially differently sized to the
original, so it won't fit - both are standard-looking concentric plugs (ie
this sort of thing: http://tinyurl.com/mx35688) but the central pin is
evidently larger on the monitor than it was on my netbook (though the
external diameter looks the same). What are the specs for these things -
how do I work out what plug I need to buy? I'm assuming it's possible to
buy a solderable version; otherwise everything I have here is welded
together - is there a neat way of cutting and rejoining the LV flex so I
could recycle what I have? (I wouldn't want to bodge it as I'll probably
pass this monitor on to someone else once it's repaired...)
Thanks for any thoughts

When my Dell laptop PSU failed, the fault turned out to be where the low
voltage cable came out. So a repair was just possible although the
original case had to be cut open.
