Internal adjustments

All of the service adjustments are accomplished either using controls inside the set (though some may be accessible by holes in the rear of the cabinet). These are usually pots on the mainboard and CRT neck boards, or in newer TVs, mostly via a service menu accessed from the remote or by using a manufacturer specific computer interface.

A Web site with some information on the general objectives of video and color setup procedures for both direct view and projection TVs is Tru-line Video Technologies.
