Dell (S)E197FPf monitor quits

I've had this (S)E197FPf monitor in combination with a Dimension E520 for about three years now, and it has quit on me with no warning. No picture, no leds, not anything. Tried switching powercord, switching power outlet, couple it to another PC, no change. I tried the on-line technical support pages (journal ID 100256046), which led to the conclusion "call Dell" (only they are closed right now in The Netherlands...). The desktop works fine with another monitor. I think is is a bit too early to junk this monitor. Any ideas?
