Flyback Arc - Proscan PS36125/CTC197CG

[Grim Reaper]

As my wife was watching it, the generally hated but my beloved Proscan PS36125/CTC197CG died spectacularly with buzing, crackling sounds and lightning flashes and a thin high brightness horizontal line in the CRT, ozone smell, then shutdown. I removed the case and turned it on which caused the relay to click 3 times with visible arcing at the top of the flyback transformer across the thin gap between the winding and the HV lead to the CRT. I cleaned off the carbon and turned it on with the same result. Is this flyback repairable? If not, I have located an OEM replacement flyback for approximately $40 including shipping. Are there other components I should replace? I bought this TV used about 5 years ago for $150, Is it worth fixing?
