Mid 80s Hitachi 19 inch picture tube problem.
 

In the mid 1980s I worked for a company where we repaired hundreds of
Hitachi tvs a month. A very few had a problem with ghosting which
looked exactly like a faulty delay line or a capacitor in the delay
line area. The problem was always the crt. I've always wondered what
kind of defect in the crt could cause this problem. Does anyone know?
Thanks. Chuck.
