a CERT showing 'fungus' (for want of a better term) is actually unsafe.
The adhesive has decayed, will it hold the layers together if the CRT
implodes?
When I removed one using a heated wire, there were noticeable large areas -
much larger than the visible problem spots - where there was very little
resistance to the cutting; I suspect there was little bond left between the
faceplate and the CRT (and completely removing the adhesive perhaps made
little difference[1] to the safety of the device).
That perhaps raises the question whether there are CRTs out there with
weakened adhesive, but which don't show any visible signs of decay.
[1] I've never personally had a CRT implode; it'd be interesting to know
how common it is (and if there's perhaps a difference between the CRT's
used in TVs and those used for computer displays?)
