MODEL:
EU-80ST
PROBLEM:
Color purity problem
File: EU80 deg cap.doc
A missing capacitor in the degaussing circuit of some units can be the cause of poor color purity. The problem
is visible when displaying a red or a white test pattern field.
Instructions
1. Check if a 100nF 275 V AC capacitor is connected in parallel
with the degaussing coil. This component should be located
on the solder side of the auxiliary PCB where the degaussing
thermistor is mounted.
2. If the capacitor mentioned in step 1 is missing, connect a
100nF 275 V AC capacitor to the terminals of the degaussing
coil connector PL201
