hello,

my Sony KV-M2151D color television has the annoying problem at the moment
that it looses its colors after it has been turned on for some time. a
while
the color starts flashing and its a half half situation but within some
minutes after that starts it turns totally black and white. it stays like
that until it gets turned of for some time, but then again it happens
after
some time.

This set uses the Sony BE2A chassis, and this fault is usually caused by
trimmer CT332 going faulty. You can clean it or replace it with a 15pF
capacitor.

Failing that, check the IF section for dry joints.
