SAFETY INSTRUCTION
WARNING :
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high
voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 22-23 kV (14”) or
24-26 kV (20” - 21”) at max beam current. The high voltage must not, under any circumstances, exceed 27.5 kV (14”,
20”), 29KV (21”). Each time a receiver requires servicing, the high voltage should be checked. It is important to use an
accurate and reliable high voltage meter.
2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X-RAY RADIATION
protection, the replacement tube must be exactly the same type tube as specified in the parts list.
SAFETY PRECAUTION
1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or
with the back cover removed involves a shock hazard from the receiver.
1)Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when
working on high voltage equipment.
2)Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if
broken, glass fragments will be violently expelled.
2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List.
3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor body 10 mm away
from the circuit board.
4. Keep wires away from high voltage or high temperature components.
5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to a DC supply of any other voltage or
frequency.
Only competent service personnel may carry out work involving the testing or repair of this equipment
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related characteristics. These characteristics are
often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be
obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are
identified by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual
carefully. The use of substitutes replacement parts which do not have the same safety characteristics as specified in the parts
list may create X-RAY Radiation.
To switch the TV set into service mode please see instruction below.
1 - Select pr. number 91
2 - Adjust sharpness to minimum and exit all menu.
3 - Quickly press the key sequence : RED - GREEN - menu
To exit SERVICE menu press menu key or Std By key.
In Service Mode press “OK” to stop the microcontroller i.e. the I2C bus is free and the set can be controlled by external equipment.
Press “OK” again to allow the microcontroller to control the set again

TV set Alignment
1 - G2 alignment
- Set TV in NORMAL I mode
- TV in AV mode without video signal ? Black screen.
- TV preset with WP Red, WP Green and WP Blue equal to 32.
- TV preset with Black R, Black G equal to 8.
- Adjust screen volume ( on FBT ) such that the highest cathode cut-off voltage measured on CRT board, is Vcut-off ± 5V.
Screen sizeVcut-off
14”115 V
20” & 21”125 V
2 - White balance
- Select a dark picture and adjust Black G and Black R to the desired colour temperature.
- Select a bright picture and adjust WP Red, WP Green, WP Blue to the desired colour temperature.

ALIGNMENT INSTRUCTIONS
3 - Focus
- Adjust the Focus volume ( on FBT ) to have the best resolution on screen.
4 - Vertical geometry
- Adjust the Vertical Amplitude, Shift, S-Correction and Slope
to compensate for vertical distortion
5 - Horizontal picture centering
- Adjust H Shift to have the picture in the center of the screen.
7 - AGC
- Adjust the antenna signal level to 68 dBµV± 2 for Daewoo tuner (63 dBµV± 1 for Philips tuner).
- Set RF AGC to 0.
- Increase RF AGC level and stop when the level on pin 6 of I501 goes below 2.5 Vdc
