I recently opened my inspiron 5150 to clean out the heat sink and the fan (which had an ample amount of dust on it). Afterwards i put it back together and booted it up. At first i thought the screen was not working, until i noticed a very dark image appear on the screen. I can only just see what is on the screen. The contrast is all the way up. I think the backlight is buggered, but i dont know much about screens.
wow, i had this exact same problem with my 5150 a few months back. I was on a flight watching a movie when i had to use the washroom... i closed the screen and left, when i got back to finish my movie everything was black, i assumed the battery died or something. when i got back home however i noticed the same very faint, very dark picture you experienced. I called Dell, they ran me through some red tape, and finally decided i should send it in and get it fixed (out of dell's warrenty, still have some warrenty left with VISA however). So they shipped me a box, but before the box even got here the screen just decided it was gonna work again (i pressed FN CRT/LCD a lot to get it working). It lasted for about 2 weeks then it went out again for a few days, then it came back again. It's been going good for about 3 months now, and i only have about 2 months left on my warrenty... should I get this thing looked at? can i really bring it anywhere and expect them to do work on it when it's actually working like it is now? i really don't want this thing to die on me now, just after my warrenty ends.
Thanks. I opened my laptop again and pulled everything out and put it all back again, checking all the connections. I found that the LCD connection was loose. Pushed it in and it worked...YAY. soon_going_apple, I recommend opening your laptop by takin the keyboard out (unclip the blue covering above the keyboard and unscrew), and pushing in the connector for the LCD. It is probably loose.
