Receiver Setting-up Procedure

Abstract

The purpose of setting up a receiver is to ensure that it is capable of displaying a picture according to its design specifications and to the high standards of broadcasting. The TV receiver must also operate within the margins of safety prescribed by the manufacturers. The need for setting-up arises either as part of the installation checks on a new receiver or as the adjustments after certain repairs or as a result of receiver ageing. The procedure is more involved—and more critical—in colour receivers than in transistorised monochrome sets. In turn, those receivers which use a delta gun tube require a greater amount of effort to produce an acceptable picture, since their convergence is more complex than that of the in-line, or precision-in-line, tube.
