Here is a good deal for a repair project in the North East. There's about a 90% chance that recapping the Deflection board and reflowing solder on the ICs will fix the vertical line collapse. Good luck. Thanks to Patron Robert Jones for sharing it.
For Parts, This is a professional grade Sony Trinitron PVM-2030 CRT Retro Gaming Monitor TV/Television. Its being sold for parts or to be repaired since my dog decided to chew the power cord while I was at work one day.
