Dell Inspiron B130 was black when turned on. Holding flashlight to screen, could see desktop and all icons. Was able to open programs, etc., while looking with flashlight. Replaced LCD Inverter listed for B130. It turned on fine, worked about 2 days, then started flickering, and went black again. Could this be power surge from motherboard, or backlight instead? By the LCD Inverter I purchased working for a couple of days, I felt like that was the problem, but something is knocking it out again.

I have a BL51 Acer Aspire. When I power it up the screen is just blank. I do see the light on showing HD activity,but nothing on the screen. My first thought would be a faulty LCD inverter! But I don't want to just start replacing parts that may or may not fix the problem. The only thing I know to try last but not least,would be to hook up an external monitor to it and see what happens!
