Officially yes. All HPs after (and including) the clamshell models (18C,
28C, etc) are non-repairale. The cases are heat-staked together.
OF course what's officially possible, and what enthusiasts get up to are
2 completely different things :-). The Clamshell models are probaly the
worst to work on (gettign them to stay reassembled is a pain), but others
can be done fairly easily.

There are 4 heatstakes in the battery compartment, 4 under the metal trim
on the keyboard. The former are easy to deal with (cut off the tops using
a 3.5mm twist drill bit held in your fingers). Some people then 'rip' the
machine apart, I am always worried that will damage the keyboard, so I
carefully peel off the metal overlay (use a long thin rod under the
overlay between each row of keys) and then drill out those heatstakes too.
Removeing the PCB is then easy...
Bu the only place you'll get a replacement LCD from is another 32S-II,
and in my expeirence, cracked LCD glass is by far the most common failure.
