Repair
Looks like sync has gone but clears after a while or after repowering, also may encounter some size issues
Change C911 C913 C422
Poor colour definition with brightness issues, sometimes intermittent
Change C332
Monitor does not power up or cuts out
There are many reasons for this, here are some that I know of:
Check the fuses first
If you get a line across the horizontal and then the chassis shuts down then there is a fault on the vertical deflection circuit
Signs of frame foldover
Change C433 R433
If full vertical frame collapse then also change R436 Q401 Q402 C437
Setting B+
Set to +94V using the "+B Adjust" potentiometer, located below the metal shield close to the flyback. Measure between TP1 and TP2, located close to the middle fuse.
