I have a comment regarding the Sony service manual for the CPD-200GS.
On page 2-2 it recommends shorting the anode and the anode cap to
chassis ground or aquadag AFTER removing the anode cap! What's more
there's a diagram that indicates one should NOT slide a screwdriver
under the rubber cap.

Sony's been making CRTs for a long time so it seems strange they would
recommend a dangerous procedure like that. Any cracks or pinholes in
the rubber and you could wind up getting quite a jolt.

It does seem strange.

Perhaps they were worried about scratching the CRT? The glass is
relatively
thin in that area.....


Perhaps it's a throwback to the old Trinitron tubes which IIRC had a special
anode cap with concentric contacts. They had a special tool to slide under
the rubber and release the 'catch', though it could be done with a little
care and a screwdriver.
