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.

OK I have the purity fixed up perfectly now. I need to adjust the
rotation (tilt) of the pic tho, it is off by about 3/8". Does this set
have that adjustment in a service menu? I would need to know how to
activate that menu. I know I could open the set up again and adjust the
yoke manually, but I like to try the electronic tilt if possible.

Thanks,
