SAFETY PRECAUTIONS

IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the
Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent
X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.

repaired before it is returned to the customer.
When replacing a high wattage resistor (Oxide Metal Film Resistor,
over 1W), keep the resistor 10mm away from PCB.

Keep wires away from high voltage or high temperature parts. Leakage Current Hot Check circuit

Due to high vacuum and large surface area of picture tube, AC Volt-meter

If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1M and 5.2M.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.

[CASE]
First adjust the coordinate much away from the target value(x, y).
1. x, y > target
1) Decrease the R, G.

2. x, y < target
1) First decrease the B gain,
2) Decrease the one of the others.
- In case of decreasing the x, decreasing the R : fix G
- In case of decreasing the y , decreasing the G : fix R

3. x > target , y < target
1) First decrease B, so make y a little more than the target.
2) Adjust x value by decreasing the R

4. x < target , y > target
1) First decrease B, so make x a little more than the target.
2) Adjust x value by decreasing the G

(7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
