need help with SONY model

[Popester]

Hi everyone. I have purchased a Sony KV-8000 on ebay that worked until recently. I have lost luminance. I still have high voltage and have color, but I've lost something in the video channel. I'm wondering if a transistor stage quit or if I have a coupling cap gone bad. Anyway here is my question. There is an ebay listing of the Sony schematic on ebay that I'm pondering on purchasing, but it is listed as "Canadian Model". All the original Sony schematics I have always purchased said "US and Canadian Model". Would there be any difference in this manual compared to the US model? Both countries are NTSC and on 60Hz. I'm wondering if part numbers would be different for components between the 2 countries. Any ideas?? Popester
