Hallo Alle,
ich habe bei den Engländer folgenden Reparaturtipp gefunden:
Symptom:
Bad focus or focus varies in a new set or after CRT replacement
Possible solution:
Short circuit the focus and the G2 pins of the picture tube with the aquadag coating. Switch the set on for approximately 5 seconds.
After this return the set to its original condition. Check if the focus adjusted normally.
Diesen Tipp geben die vorallem für alle Philips Chassis an.
Macht das Sinn?
Gruß
