How do you know it works. Verified it in another monitor?

Not sure how you drew the conclusion that because the deflection PCB is fine, the chassis transistors are ok...did you replace them recently?

One time I had a WG6100 where I had known good deflection board, HV, and transistors, and the extact same problem (only half screen). I took out a large plastic handled screw driver, turned the monitor on, and began to whack the chassis mounted deflection transistors with the plastic end. The picture would jump to full screen momentarily. I pulled and remounted the suspect transistor, and the monitor came up fine.

There's a technical solution for ya! :-)
