Most of the TV's and monitors today, use a service mode for performing
adjustments. Some models can have the service mode accessed via the
remote control, while others use a dedicated external interface device
of some type. In most cases, the shop service manual is required to use
the service mode.

If any parameters have changed in the set, proper service to locate and
change the defective components should be done, rather than mess with
the service mode. The service mode has been set up during the
manufacturing process. Once done, it hsould not ever need to be teaked,
unless a critical part has been changed.
