I have to replace the FBT in a Sony TV model KV-4490. (Inside it's labelled
as KV-2781R, chassis SCC-552P-A). Can I disconnect the HOT wire from the
HVR and if yes, how?

The HV output from the flyback goes to the rectangular HVR mounted on the
metal CRT shield. The HVR has two hollow posts on top with the HV wires
going down inside them (one from the FBT, the other from the CRT). Does
the wire from the FBT simply come out? (It's snug and I haven't tried hard
to pull it out.)

(Reply to group, please.)
