DELL 630-DIM DISPLAY

THE UNIT WAS CAME FOR REPAIRING DIM DISPLAY PROBLEM. I CHECKED AND FOUND THE INVERTER WAS OK BUT THE ENABLE SIGNAL 3.3V WAS MISSING. I REPLACED THE ORIGINAL INVERTER BY ONE GOOD UNIVERSAL INVERTER. PUT JUMPER FROM 3.3VS AS ENABLE SIGNAL FOR THE INVERTER. NOW THE DIM DISPLAY CASE WAS CLOSED. THE CUSTOMER WAS HAPPY.
