Question about Acer Aspire 3100-1405 Notebook
Just bought thow is was fine earlier today now screen is dark you can faintly see start up screen, adjusted brightness no luck
Since the Acer Aspire 5315 works except that the display is dark, then it would be safe to assume that it is only the LCD display part that is the issue. Often LCD display (of laptops) are working but only that you can not see the actual display. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance or part of the desktop could be seen. If the desktop could be seen (albeit very very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps.
Often, the defective component would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the display panel of the laptop than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Acer Aspire 5315.
This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
