That "stock" photo appears in the Sams Photofact, so thank them.
I looked up your model number in Sams and saw this photo with knobs on the side and top. Your cabinet may have a somewhat different style, of course; it was common to offer the same chassis in various cabinets.
Anyhow, if you are talking to a repairman, tell them the Sams manual is Set 429, Folder 1 (assuming that the Canadian model numbers and Sams number are the same).
Good luck getting yours fixed. These are nice TVs when working properly.
