Static convergence on Thomson 52RG75J?

    Hello group,

    Anyone know how to adjust the static convergence on a Thomson 52RG75J (ICC9
    chassis)?
    Dynamic convergence is done with pots under the front facade, but I think
    static convergence is normally done using a service mode in the remote
    control. Is this correct?
    I don't have an original remote control, so can't enter the service menu
    (on orig. menu and + buttons simultaneously). Is there any key sequence that
    can be used on a universal remote control to enter the service mode?

    thanks
    Dan

    Static is normally relating to mechanical adjustments such as centering,
    width, height, etc. Dynamic on all relatively new chasis is always done via
    a technician setup menu.

    Thanks, but the generalities I know already. I'm looking for the specifics
    on this one. It's an old design rear screen projector, with potentiometers
    for the dynamic convergence, and I can see on the schematic that the static
    convergence levels (centering etc) are set by a DAC chip on the I2C bus.
    Therfore I assume that setting is done by the remote control.
