Was that bashing done with power on to the tube ?
This rubber hammer bashing technique is near the bottom on my" to do" list right
before I take the CRT outside and use it for target practice (a safe distance of
course).
On the other hand I might just stick the set outside when the temperature is 22
degrees below zero just to see what happens (the little strips should maybe
contract a bit ). Also been wondering about trying a vibrator.

Try unplugging the degaussing coil and then degaussing it. I've seen
Sony sets where manual degaussing didn't help until the degaussing
coil was unplugged from the defective degaussing circuit.

I've seen Trinitron CRTs with aperture grill wires that were stuck
together and it looks like sharp vertical lines of incorrect purity,
not large areas. I've only ever seen it on a computer monitor. I
think the wires are too far apart for this to happen on a TV.

The aperture grill functions exactly the same way as a shadow mask.
It's just a *** of metal with thin slits cut in it. A shadow mask
is made of similar metal, but has slots or holes instead of slits.
