Dark screen inverter already changed, problem still alive

Текст:

Where and what is the PWM exactly?

Is it a simple IC or something else?

Are there points I can measure with my multimeter?

On the primary side of the inverter I have 3,2-5-ground-12,6 volt.

Is this the right voltage?

I can't check a AC voltage over 600V.

My display only lights up one time (when I regulate from zero to first dim regulation - software) or I plug out in the inverter?

What now? Any ideas?

thx
