Ordinarilly i would say it's abad CRT. Sonys are famous for the
'reddish brown " syndrome. It seems though, that you got lucky and
dislodged some debris from the gun. Run it for 24hrs or so and see if
the problem returns. If it doesn't, it may be OK for some to come...
I would tell the customer that the CRT is marginal and subject to
failure for CYA purposes.
