Model # KV-27EXR25 # on flyback is 1-439-423-41 shows NLA from
Global Semi, but looks like 1-439-416-41 is a sub. Can anyone confirm?
Unit starts up, HV is ok, then immediate shutdown. Repaired the
horizontal
connections, & replaced the STRS6301 regulator. Thanks, Dani.

When posting, you should always mention the model number. Sony makes many
models that are different from each other.

In the Sony set, if the flyback is defective, it is a very wise idea to also
change the horizontal output transistor as well. Also do an ESR test on all
the capacitors in the horizontal scan area, including on the output side of
the flyback. High ESR caps in these areas can also cause failures. If there
are any non found defective components in the horizontal area after the
power is re-applied, you will most likely have to replace the new parts
again.

As for the flyback replacement, you will have to trust the supplier. If the
set is more than about 6 years old, I would be considering a new one, rather
than put money in to the one you have.

1-439-416-41 is the correct number and is available from Global on order.
Hold on to your wallet its costly as hell.
