    I have a VSYNC Problem on Davio 20" (LCD CONTROLLER: U200/GM2221/GM5221/GENESIS).
    Power supply/capacitors are OK. Factory settings applied.
    I think that the TV processor VCT49X3FPZF1000 is not working properly(when I ground VSYNC from it, video signals added after(e.g. on-display menu) have no VSYNC problem anymore)
    Any ideas/help are very welcome.

    Best regards,

    Model : Grundig LCD 51-4505 Top
    Chassis : L5C
