The screen on my Inspiron n4010 in no longer working. The screen is white with vertical lines. I can link to an external monitor and have no problem seeing the screen on the external monitor. Does this mean that my video card is good? If the video card I good can I simply replace the LCD screen? Can I replace the screen alone or do I need to replace the inverter? My laptop is no longer under warranty. I would like to repair this as economically as possible. I have had it for a little over a year. During this time and while still under warranty, it was will Dell for repairs. Part of the problem then was the sound. So far I have not been impressed with my Dell.
Thanks so much for your help.
I would recommend you to check the screen in BIOS. Turn on the system; Press <F2> at the initial Dell logo screen to enter System Setup. In case you see vertical lines in BIOS then there is a problem with the LCD screen.
After that I would also suggest you to run Dell diagnostics as well. Turn on the system, press <F12> at the initial Dell logo screen, and select Diagnostics from the boot menu.
During the Pre-Boot System Assessment, the Video Test will present you a screen with colors bars and you will get a message, “Were Color Bars Displayed (Y/N)" press the <N> key to perform the LCD Built in Self-Test (BIST)
In case above test fails LCD screen has to be replaced.
