I've got a Valvo vcc91 that worked perfectly a long time ago.
But now only the lower half of the screen displays something. It turns yellow if we fire the brightness up, but our GeForce mx440 with 15Khz. mod shows the windows desktop on the lower half too.
I tried fixing the two adjustment prints by re-soldering the joints. Even checked al the other contacts but still nothing. Only - with or without a device - the lower half of the screen.
The pot concerning it will only move it very little but the multimeter tells us it is OK.
Hopefully someone can tell us anything more about this.
Before I forgot, the other pots seem OK, and so do the capacitators.
