Chosen Solution
Hello, after I start my laptop the load-screen is shown for about 10 sec after this the screen turns black. I know the laptop is still working and Windows is loading but without any graphic. When I connect the laptop with an external Display, it works and I see the desktop external. This means the graphic card works but the laptop-display stays black. When I push the function button with f6 the lightning button the screen appears for some seconds on the laptop-screen and again nothing. What could be the Problem? Thanks in advance. Regards
YET, sounds like a backlight issue. This could be related to the screen or the inverter. I would start with a new inverter. Relatively inexpensive and not very difficult to change. Thsi video will give you an idea of what you are looking at.
I changed the inverter and the problem is still there. Now Im sure it should be the screen itself. Thank You.
I had same problem on my Aspire 8920g in 2013. Just want to share my solution. oldturkey03 is right that the problem is with backlight. I solved it in two steps. Starting with easiest. First - replace inverter, in my case the problem was still there, but for some users it can be solution. Second - replace LCD CCFL Backlight. This step is more difficult, but with patience and skilled hand it is less than 2 hour job. To change CCFL is cheaper than whole screen. You can find them for under $20, just search eBay for “LCD CCFL Backlight Aspire 8920”, example eBay link I did this repair in 2013 and still PC is working without problems.
