DSO Quad Display gone pale - like overexposed foto

Products & Technology DSO Quad

Hello,
when fiddling with the trigger menue and channel A sensitivity (with ChA Probe on
5V DAC signal) suddenly the display became very bright, looks loke overexposed foto.
Dark blue is no longer readable at all - the whole display looks like it has gray vertical
grid lines.

It is not the Backlight (BL) setting - I tried all percentages.

What I did without any susccess:

  1. power down / up several times
  2. remove battery for some minutes

Is there a way - maybe setting - to udjust the overall display intensity?
Any help greatly appreciated!

kind regards
Matthias
