Dear all,
The screen of my CSA803A developed a problem. It showes flyback lines, low intensity and I could not get it calibrated properly. The size of the picture, focus and convergence are o.k..
After removing the CRT driver board A8 (671-1027-01), it turned out that a (zener?) diode is completely burned and also a 100uF/50V elco did not look healthy. This diode is immediately below the metal box shielding the flyback transformer and alongside what seems to be a very big tantalum elco.
Any help in finding the type of this diode is very much appreciated!
Kind regards, Gerard
