    I did a diagnostics test for the video card fan and got the error message:
    Error code 3700:011B
    Expected video fan low RPM of 2500
    Detected fan RPM = 3512

    Does this mean I need to replace the video card fan or the entire video card?

    Thanks john

    After completing the diagnostics the display is now back to its normal condition, do you still think I should replace the fan?

Hi,

From the symptoms and a breif discussion with Dell technical support its clear that there is an issue with the Video card and the fan located on it.

Run the Dell diagnostics to verify the operation of the fans. If the video card fan is not running, DO NOT use the system - you'll turn a $50 fan replacement into the need to replace a $400 video card.

If this card has been in your system for a while, not a new install, then your GPU is going bad. You might try updating drivers for the GPU and testing the memory, but it looks like a bad GPU chip.
No changes to your monitor? No chance the monitor cable from the unit is loose, checked the connections on both ends?
Run the Dell Diagnostics for hardware, on F12 Boot Sequence, drop down to Diagnostics, you can check the memtest, prepost, etc, but you need to drop down and do a hardware test or a system tree test.

Please follow the link bellow to understand how to replace the graphics card.

Charging light is flashing


There are two possible causes for this issue:
1) Your dell 9400 charger is malfunction
2) Your laptop dc power jack is loose or dead

Possible troubleshooting step:
1) Borrow a compatible dell charger to plug in your laptop, if it works without any issue, it means your dell inspiron 9400 adapter need to be replaced.

2) If the compatible dell 9400 charger won't work normally, the problem may lie in your dc power jack.

Hope this will help.

Dell Inspiron 9400 laptop display problem


First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.

Dell Inspiron 9400 notebook display blank


Most likely, as you have said, this is already a hardware issue. For hardware issues the best thing to do is to have your system checked out by a local hardware technician. If your video is in fact the issue here then most likely you will be needing replacement for the motherboard now this costs a lot. so you have two choices really, 1) Just get a new laptop because the price of a new one will cost almost as much as replacing the part. 2) Have it fixed by Dell and have the part replaced then ask for warranty reinstatement, if they have one.

Dell Inspiron 9400 display goes blank after a few minutes


If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st
