|The screen on my Acer Aspire 6930 went almost totally black. I searched the net for an easy and inexpensive solution. I found out that the problem is either with the LCD inverter or the fluorescent light (CCFL). I decided to replace the inverter first, since it was cheaper. After replacement of the inverter, the screen was working fine. I turned the Laptop off and on three times, but the next day when I turned it on, the screen was black again. I thought it was probably a bad inverter, so I got another one (from the same online seller).|
I replaced the part for the second time and everything worked fine, until I put the PC in hibernation mode for a few hours. When I came back to use it, the screen was black again (you can hardly see the screen with flashlight). I can think of two possibilities, 1- Both inverters were defective and I should buy another one from a different source, or 2- The input DC voltage to the inverter is higher than what it’s supposed to be, thus burning the inverters.
