ADJUSTMENT Y Safety Precautions 1. It is safe to adjust after using insulating transformer between the power supply line and chassis input to PAL/SECAM-BG SYSTEM PAL-BG/DK PAL-I prevent the risk of electric shock and protect the SECAM-LL' instrument. 2. Never disconnect leads while the TV receiver is on. TUNER 6700VPF002A 6700VPF002B 6700VPF002B 3. Don't short any portion of circuits while power is on. AGC Voltage 2.3 ! 0.1V 2.3 ! 0.1V 2.1 ! 0.1V 4. The adjustment must be done by the correct appliances. But this is changeable in view of productivity. NOTE: AGC must be adjusted when the tuner was changed. 5. Unless otherwise noted, set the line voltage to 230Vac!10%, 50Hz. : Screen Voltage Adjustment
Y Test Equipment required 1. Multimeter (volt meter) 2. Oscilloscope Test Point : RK (Red Cathode of CPT Board) Adjust : Screen Control of FBT
: RF AGC (Automatic Gain Control) Adjustment 1) Tune the TV set to receive a digital pattern. 2) Press PSM (RED) button on remote controller. (standard Test Point : AGC TP (J3) picture) Adjust : Remote Control 3) Connect the probe of oscilloscope to the RK (Red Cathode) of CPT Board. 4) Adjust Screen Volume of FBT so that the waveform is the The RF AGC was aligned at the time of manufacture for same as below figure. optimum performance over a wide range conditions. Readjustment of RF AGC should not be necessary unless Horizontal unusual local conditions exist, such as ; FlyBack Time Black level 1) Channel interference in a CATV system. 160Vp-p 2) Picture bending and/or color beats, which are unusually due to excessive RF signal input when the receiver is too close to a transmitting tower or when the receiver is White level connected to an antenna distribution system where the RF 1H-LINE GND for dc signal has been amplified. In this case, the input signal should be attenuated (with pad or filter) to a satisfactory The waveform of RK(Red Cathode) of CPT Board level. 3) Picture noise caused by "broadcast noise" or weak signal. If the broadcast is "clean" and the RF signal is at least 1mV (60dBu), the picture will be noise free in any area. : Focus Adjustment
NOTE: This adjustment should be performed after warming up for 10 minutes. Adjustment 1. Connect RF signal (65dB) and turn on the TV. Test Point : Observing Display 2. Press OK buttons on TV set and Remote Controller at the Adjust : Focus control of FBT same time to get into SVC mode. 3. Press Channel UP/DOWN button on the Remote Controller 1) Tune the TV set to receive an inactive channel station. several times to find AGC. 2) Adjust the Focus control of FBT for best overall focus. 4. Press Volume UP/DOWN button until the AGC Voltage is the same as the Table below. 5. Press OK(Y) button to memorize the data.
- 1 - : Deflection Data Adjustment (Line SVC-1)
NOTE: To enter SVC mode, press "OK" buttons on both TV set and the Remote control at the same time.
1. Preparation for Deflection Adjustment 1) At SVC mode, press the Yellow colored button. If the Remote Controller doesn't have the Yellow button, you should use a Service Remote Control (105-201G) and press SVC button. And then, deflection data adjustment OSD (SVC1 mode) will be displayed. 2) Press Channel UP/DOWN button for desirous function a Adjustment. 3) Press Volume UP/DOWN button to adjust the data. b

VZ 31 0 45 29 0 43 EW (Horizontal Width) Adjust to that a digital circle pattern looks like exact circle.
EP (East-west Parabolar) Adjust so that middle portion of the outermost left and right : White Balance Adjustment.(LINE SVC-0) vertical line looks like parallel with vertical lines of the CPT. NOTE : This adjustment should be performed after screen voltage EC (East-west Coner) adjustment. Adjust so that the vertical line at every 4 corners of the screen looks like parallel with the vertical lines of the CPT. 1) Tune the TV set to receive an 100% white pattern. 2) Press OK(Y) buttons on TV set and remote controller at the ET (East-west Trapezium) same time to get into SVC mode. Adjust to make the length of top horizontal line same with it 3) Press PSM(RED) button on remote controller. (Standard of the bottom horizontal line. picture) 4) Press Channel UP/DOWN button for desirous function VZ (Zoom Mode, Vertical Height) adjustment. Select the zoom mode with ARC button and adjust the data 5) Adjust VOL+ or VOL- button for GG:31. until the lines a and b of figure are 5~10mm from the top 6) Adjust VOL+ or VOL-button in each status of "Rg--"/"Bg--" for and bottom of CPT and 3~5mm from each sides of CPT.
