Circuit Diagram
PHILIPS Confidential – Do Not Copy 105S5
A. GENERAL
1. ALL SPECIFICATION MUST BE MET OVER LINE VOLTAGE RANGE OF 90 VAC TO 264VAC
50HZ/60HZ, UNLESS OTHERWISE SPECIFIED.
2. OPERATING TEMPERATURE RANGE IS 0 DEG.C TO 40 DEG.C WITH A RELATIVE HUMIDITY OF 10%
OR LESS TO 95%.
3. THE MONITOR MUST BE OPERATIONAL IN AN USABLE STATE WITHIN 30 SECONDS AFTER TURN-
ON.
4. ALL SIGNAL LEVELS ARE MEASURED ASSUMING TERMINATION AT THE MONITOR'S INPUT
JACKS OR IN ITS CHARACTERISTIC IMPEDANCE.
5. AN AMBIENT LIGHTING LEVEL OF 400 TO 600 LUX IS ASSUMED WHEN SETTING BRIGHTNESS FOR
RASTER EXTINCTION THRESHOLD.
6. ALL PURITY RELATED SPECIFICATIONS MUST BE MET WITHOUT EXTERNAL DEGAUSSING.
7. ALL CONTROLS MUST HAVE EXCESS RANGE (NO CONTROL MAY BE LEFT AT AN END STOP
WHEN PROPER ALIGNMENT IS COMPLETED).
8. THE MONITOR IS NOT REQUIRED TO MEET SPECS DURING THE FOLLOWING BUT MUST
TOLERATE, WITHOUT DAMAGE TO THE CRT OR CIRCUITS, ANY SEQUENCY OR COMBINATION OF
POWER ON AND OFF, SIGNAL ON AND OFF, UNPLUGGING OF POWER OR SIGNAL, ERRATIC,
WRONG FREQUENCY OR NOISY INPUTS WH ILE AT ANY POSSIBLE SETTINGS OF USER
ACCESSIBLE CONTROLS. LIKEWISE, THE MONITOR SHOULD SURVIVE EXTENDED PERIODS OF
OPERATION WITH LINE VOLTAGE REDUCED BELOW THE SPECIFIED MINIMUM
9. AN ISOLATION TRANSFORMER SHOULD BE USED WHEN PERFORMING ALIGNMENT AND TESTS.
PORTIONS OF THE POWER SUPPLY BOARD ARE HOT GROUND. THE REMAINING BOARDS ARE
COLD GROUND.
10. DISCHARGE OF CRT ANODE SHOULD BE DONE ONLY TO CRT GROUND STRAP.
11. GEOMETRIC MEASUREMENT IS ASSUMED TO BE MAKING ALONG A STRAIGHT SURFACE WITH A
FLAT RULE OR TEMPLATE
