Be very careful! If the two power supplies have different IDs, it's
for a good reason. One will be stabilised and the other won't. An

How would I know if one PSU was stabilised? There's nothing relevant
written on either of them AFAICS. The working PSU was a laptop
charger - is that likely to mean it might be stabilised and that the
purpose- supplied item for a monitor might not have been?

Its is almost guaranteed that both will be switched mode supplies (and
hence regulated / stabilised)

Thanks John. Looks like the next step is to try and get inside the welded
faulty PSU without damaging it, and work out whether it's the flex that's
broken or the electronics; if the flex is OK I'll transfer it to the new
PSU via solder/heatshrink.
