However, there's a flexible plastic strip running
between the CRT face and
the chassis which carries three lines (it's a storage tube rather than a
conventional CRT) and I'm still getting periodic arcing across these lines
which of course upsets the display's operation. As far as I can tell,
there's no 'sandwich' (and hence glue) involved - it's just a single
plastic strip with conductive traces drawn onto it.
What does this strip connect to? Is it part of the CRT (or connected to the CRT), does
it connect to a coil around the CRT, or what?
I am wondering if there is something else leaking or flashing over which is causing
excessive voltage to appear here.
