This one was dropped on the bottom left corner by the looks of the
cracks in the case. Now it has bad purity down the left side, and the
bottom right corner. I have found some info on the net here;

I thought I would check here to see if there are any alternatives to
trying magnets etc to get the purity back. I seem to recall that the
rings on the neck of the CRT used to be used for purity too, but these
ones have not moved.

Thanks,


If it was dropped the shadow mask inside the tube has shifted and you need
magnets.


I thought it would be something like that. I experimented with my
magnetic screwdriver, and I was able to almost eliminate most of the
problem on the left side while it was near the back of the CRT, so maybe
I'll experiment some more with magnets.

It probably doesn't matter at this point, but I had the symptoms
reversed. It was dropped on the right corner and the purity problem was
mostly down the left side.

Thanks for the info.

Just an update...

I have 6 magnets on the CRT right now, and the problem is almost gone. I
just have to remove one small area at the top and it will be good as new
again. It's hard to imagine that sticking magnets on the CRT would
resolve the issue so well, but hey the results prove the theory.

I'll get at it again tomorrow.

Thanks to Meat Plow for the heads up...
