mbcoupe Posted July 24, 2013 Share Posted July 24, 2013 hello all im new to this forum and i know it only concerns OSX installs ..but after looking at the posts its obvious to me that the members REALLY know WHATS UP.... i have a delld630 with the Nvidia chip that did the well known failure seen in most of these laptops.. blank screen.. using ext monitor showed that the creen worked but 4 colors and 600x480 was the res. and (obviously) could not be changed.. im assuming this was a bare bones video mode used by the bios chip or whatever that was bypassing the graphics card.. so bottom line i did a reflow of the nividia card and lo and behold it worked !! kinda.. with ext monito the graphics are fine now 1200x1074 i think with all display options selectable... NOW for my issue.. the screen on the laptop looks like it has no backlight .. i can still see it if held just right just barely almost like a negative chromatic color screen... how do i tell if its the inverter or the screen without trying a new one Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted July 24, 2013 Administrators Share Posted July 24, 2013 well does it work in bios setup or boot? as for testing .... you would have to test with a known good inverter board.or swap your inverter to a known working screen. no real way to test a CFL tube inside the screen directly.
