DEGAUSSING
There are 3 states that degaussing device of monitor will execute.
Picture moves due to the degaussing device working after Select "DEGAUSS" (OSD screen or
Front Control Knob) and press the OK button (front control of montor), but it is normal.
1. Power on monitor.
2. The monitor wakes up from sleep mode.
3. "DEGAUSS" selection and execute it.
Degause the set in the on screen menu.
Please be aware that many models will not degauss more than once
within any given time period (up to 10 minutes).
This is due to the unit having a temperature sensitive resistor.
While the unit is degaussing, the resistor increases in value with heat and
once it reaches a certain temperature, the resistance will rise and prevent voltage
from reaching the degaussing coil. This is what stops the degauser,
and this devices resistance will decrease as it cools back off enabling the degause to operate again.
This is an intentional design and is a industry standard, not just Philips.
A nearby magnetic field may magnetize the CRT.
Move the unit to another location and perform degaussing as mentioned above.
If the unit has been recently moved , the earth 's magnetic field may have magnetized the CRT.
Perform degaussing as mentioned aboved.
If the unit has been dropped ,the CRT shadow mask may be loose.
