I have a Dell Inspiron 6000 that has LCD issues, at first when you booted it up the screen would flash on with a red tint, then go off. I replace the inverter and that didn’t work same thing, I then replaced the backlight, ” that was fun ” now when I boot up it comes up bright but after like 30 seconds goes really dim again, you can see the desktop with a flashlight. If i use an external monitor it works just fine. Would this be the LCD it’s self or motherboard ? I’m confused at this point.
