Hi Irinkus,
The fault may not be with the flyback transformer. To have static electricity on the screen, the unit must produce EHT, which uses the flyback. But it depends on the horizontal deflection working also. One of the most failure prone components in a CRT monitor is the horizontal deflection driver, called the horizontal output transistor (HOT).
Since this monitor is a Trinitron, it also has a horizontal convergence block that is suspect. If the HSTAT block has drifted, it can shut down the EHT (it does this to provide X-ray protection).
