Page 5: Introduction
INTRODUCTION This technical manual contains operation and maintenance instructions for the EDL Model 6115, 6116, 6119 and 6120 MasterSync Video Monitors. These models are high quality, high performance, high resolution color monitors. They are unique in their ability to automatically synchronize and display virtually any video format. -
Page 6: General Information
VERY HIGH RESOLUTION EDL Displays Color Monitors have the highest resolutions available. The dynamically focused 0.28mm dot pitch (0.25 for Model 6120)cathode ray tubes provide the sharpest images available with resolutions up to and including 1600 x 1280 for 6119 &... -

An important benefit of these plug-in replaceable modules is the very short Mean- Time-To-Repair (MTTR). Since the replaceable modules are the same as used in other EDL Displays products, sparing and personnel training are greatly simplified. LOOP THRU OPERATION Loop thru operation is provided by a HI-LO impedance switch selection. -

Page 22: Operation
OPERATION The method of operation of the Models 6115, 6116, 6119, & 6120 is similar to ordinary monitors with respect to power, brightness, contrast and deGauss. However, they do have an additional mode called "Calibrate". The "Calibrate" mode permits the user to program an internal microprocessor to memorize alignment parameters for 21 different video formats.. -

TROUBLESHOOTING FAULT ISOLATION/TROUBLE SHOOTING Most problems in the Model 6115, 6116, 6119, & 6120 video monitors can be isolated to a single module or pair of modules by careful observation and interpretation of the display presentation, the LEDs on the rear panel and various mechanical items. Generally, most problems are manifested by either a display presentation which is incorrect or no display at all. -
