Sony KV-1215 Schematic

[85Skyhawk]

Hello,
I'm looking for a schematic for an old Sony 13" Trinitron TV set. The model number is KV-1215 but any schematic from a similar set would be appreciated. I'm having trouble with the vertical section since picture was totally collapsed. I replaced two transistors and still am about an inch or so shy of the top of the picture tube. The set is old so I really don't want to invest a lot of money into it.
Regards,
Erik
