Sont Watchman case opening???

[dtvmcdonald]

At the Eartly TV Convention I bout an old Sony Watchman,
a B&W CRT model with the strange flat picture tube, about a 2"
diagonal screen. Before buying I turned it on and got the behavior
expected tuning through digital stations.

Back home we have a Ch. 39 analog left and I have a Ch. 10
Blonder-Tongue modulator into an antenna. The video works
perfectly.

When I first tried it it the sound worked. Then it started
motorboating on and off and then when I tried new batteries
the sound didn't work at all. Probably a bad electrolytic.

I decided to open it up and see if it looked fixable. Its obvious
how to open it (unlike some of these, Sony actually had arrows pointing to
the correct screws!) and I got 5 of the six screws out and
was able to look inside, and it looks fixable. BUT ... I can't get
out the sixth tiny screw. It just spins ... and tying to pull
on the screw (easy since the back is fully loose) does not help.
HOW does one get these things undone?

What model is it? I remember a problem on one of these that caused me to drill out the screw... on another one, I just gave up. Hopefully, somebody here will have some better ideas.

I don't think a drill will work ... it will spin. A long narrow
Dremel tool grinder will, but I don't want to do that unless
as a last resort, since it will destroy the screw.

It may be an FD230.

OK, I just took the back off of a 230... the 2 top screws go into a metal bracket (that the lanyard is attached to). The other 4 just screw into plastic posts... these should be no problem. The 2 screws on the very top of the cabinet fasten the bracket and antenna to the case... if those are removed, you could perhaps pull the set apart with the board still attached to the back, for access to striped screw.

Is there away to pry the case in the area of the screw to see if the extra tension will cause the screw or brass threaded insert if it has those, to "bite" on the remaining plastic in the hole? The prying action might also pop the housing open. Might crack it too...

With similar screw troubles in the past I just put some quick-acting superglue on the end of the screwdriver and held it into the screw head until it bonded, then unscrewed it. Solvent will then clean off the screw and driver.
