Backlight wont turn on I have a MC218 - Computers & Internet

If you have a very dim display, or no backlight it could be due to a few things. A loose LCD cable could cause the problem, a very basic way to test this would be to apply pressure to various parts of the laptop case and screen bezel, also move the screen and see if a backlight ever powers on. If you are comfortable opening your laptop to check connections then do so. A faulty cable is also a possibility. Sometimes it is a software issue, try turning your display brightness up to max, does the backlight illuminate when in BIOS? If so it is a software problem. Finally it could be a failed LCD inverter, this is a bit of hardware usually separate from the LCD although is sometimes built onto it. These are generally easy and reasonably cheap to replace.<br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB">Hope this helps,</span><br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB"><a rel='nofollow' href="http://www.putercare.com/">www.PuterCare.com</a></span><br />
