Chassis E9-service manual
SERVICE ADJUSTMENTS OF THE COLOUR TV WITH E9 CHASSIS All necessary adjustments and settings are performed during manufacture of TV set and assure its correct operation when connected to the mains voltage and antenna or external video or audio signal. When TV set requires service intervention all settings should be checked and corrected, if necessary. DEMAGNETISING OF PICTURE TUBE Correctness of picture tube demagnetising is usually automatically checked. Magnetisation of picture tube is presented as one or more colour "clouds", consequently colour reproduction of the picture is not correct. Each time the TV set is switched on with mains switch, demagnetising system is activated. For correct demagnetising procedure disconnect the TV set with mains switch and leave it disconnected for about 15 minutes. Afterwards when you switch on the TV, demagnetising procedure is performed. In case distortion of colour reproduction still persists, special demagnetising coil should be used. ADJUSTMENT ADJUSTMENT CONDITION ADJUSTMENT ACTIVITY AND RESULT OF SETTINGS 1.
