Yes, it could really be a weak picture tube causing the flashing. Do a
google groups search for Sony, flashing picture, blinking picture, akb
blanking, and similar for lots of postings on how the Sony AKB circuit
works.

Some internal adjustments on the main grid bias voltages might buy you
some time. Best to only call a Sony authorized and trained servicer,
or known experienced independent servicer, and only after getting other
recommendations and referenced.


A weak tube on a 1999 set? I'm curious how many hours a day this thing was
used.
