|  [crt/lcd] Dell Inspiron E1405 LCD Problems
Hello all,
I'm experiencing a weird issue with a Dell Inspiron E1405 laptop. I'm working on it for a friend, and thought I had it figured out, it seemed like an inverter failure was causing the LCD to not light up. We bought a replacement inverter and it seemed to work. The BIOS/BOOT menu showed up bright as day and clearer than before, and during boot and startup it was fine, until it gets to the Desktop. Once the Desktop loads, the screen goes black as though the backlight is dead again. Turning the machine off and then turning it back on yields the same results: Bright and clear during boot, completely black when OS is loaded. I thought it may have been an OS misconfiguration issue until I booted with an Ubuntu CD and the same exact problem. OS loads and loads, I get a mouse cursor, the background shows up, and then complete darkness.
I'm thinking it's the backlight or the entire LCD itself. If it is the backlight, I would probably end up replacing the entire LCD anyways.
Any recommendations? |

When you power up, the system bios starts the video bios and initializes the display adapter..
When the OS boots, it loads the graphic drivers and starts the display adapter.
If the display was bad, you wouldn't have any graphics during the start-up sequence.
We need to figure out what's gone haywire. Step one would be to boot into safe mode and see what happens.

| I figured that booting with a known-good Ubuntu CD would rule out generic display adapter driver problems. I will try booting into safe mode when I get home though.

Ok Chip, I booted into SafeMode with Networking and the screen looks fine, it doesn't look like this at all in normal Windows. So maybe the graphics drivers are corrupt? I will try reinstalling the video drivers and seeing what happens.
Thanks! =)

No such luck, I still get a Windows XP loading screen and bar, but complete darkness when it's booted into Windows. I can vaguely see the start menu and desktop as though the screen is VERY dim, but I can't see enough to change anything.
I have hooked the machine up to an external monitor and everything appears to be working that way. Is it possible that the backlight or LCD is damaged, preventing it from working when full-screen graphics are on screen? It seems like the only logical next step.
EDIT: When the machine is hooked up to external display, the internal and external displays work perfectly. Unhooking the external display while both are working renders the internal display dark again. ... I am REALLY confused.

Well, I tooled around in the Intel Graphics Options menu after hooking it up to the external display, and disabled the external display from in that menu and suddenly the internal menu works. It's working after multiple reboots. Thanks for your help Chip, I think the driver reinstallation helped it out.
