Actually I've repaired a problem like this on a Sony 27" I got at a
garage sale for $1, The sellers kids had ripped the coax out of the
back taking the connector and a few of the coils with it. All the parts
were still there and I was able to reassemble them and rewind the
broken coils with guesswork. It's been working fine now for 5 years.
You could attempt this if you want the experience and you're good at
soldering.
