I got the exact problem. I tryed changing the inverter without success, then I tryed to changing the inverter cable no success. If the brigthness il set to max (16/16) the screen go black after few seconds, if setted to 7/16 bars the screen works whit random blackout, if I increase one bar (8/16) works for few seconds then go black again. I just ordered a new inverter, hoping that the refurbished one I bought was broken. when the screen go black, to turn it on again I have to set brightness down to zero (0/16) (F1) and then increase (F2). I need some advice. Do I need to replace the LCD Screen? Cris (sorry for my English ^_-)
