Latitude D830 screen stopped working

Hi,

I would recommend you to perform flea power. Unplug all external peripherals like printers and remove the power cable from the system. Hold the power button down for 10-20 seconds to drain flea power.

If the issue still persists, would suggest you to launch the diagnostics on this system, perform one of the following actions:

• Hold down the Fn key while pressing the power button.
• Turn on the system, press F12 at the initial Dell logo screen, and select Diagnostics from the boot menu.
• Disconnect the AC power and remove the battery. While holding down the power button, insert the AC connector into the back of the system. The system then starts and the message- Diagnostic boot selected displays. The system then launches the diagnostics.

Please check for any error codes. If you are not able to see any error codes, check for any beep codes.

Please reply.

Thanks and Regards

Sounds like the video chip has failed - you will need a replacement mainboard.

I tried to drain the flea power and it didn’t help.

I ran the diagnostic and the results were “ a possible graphics card/video failure has occurred”

Alas I think you may be right

Hi,

The error message suggests to be a graphic card failure. Since the graphic card is fused on the motherboard itself, so it needs to be replaced.

I suggest you to check the warranty status on Dell's support site by inserting the system Service Tag.

Please reply for further queries.

Thanks and Regards

I have the same issue.

I have followed the steps litterally and don't get a video signal on the D830 LCD. However I Do get a signal on an external LCD via VGA-out when pressing "FN + F8" (switch between built-in LCD and CRT/LCD).

Still graphicscard? I'm thinking No due to the fact that I'm still getting an external video signal.

Please advice.

*** UPDATE ***

After running a diagnostic with external LCD the problem wenet away.

*** PROBLEM SOLVED ***

I want help and support from Dell community that's why I have created account  

After diagnostic the error message was like as follows 

Error code o146

Msg: error code 2000 - 0146

Msg: unit 1 :DST log contains previous error (S)

Is this the first time you've seen that?  If so, you have a dying hard drive.

i am facing black screen problem. but when i connect external lcd it gives the display. only laptop's LCD is not giving display.

please info me if one knows the solution as early as possible. thanks  and i am waiting

This tip is derived from similar problem with older Dell models described on the internet. (D830 was overheating, and stopped booting)

Disassemble laptop completely (see Youtube movie), including heat sink. Remove layer of dust between fan & heat sink.

Create mask out of alufoil, covering complete motherboard, but leaving open the 3 chips (including CPU & GPU).

Heat all 3 chips separately during approx 5 minutes up to approx. 200 C using a hairdryer or paint stripping gun.

Mount heatsink using new paste, and assemble laptop. Worked for me. Temperature of CPU/GPU remains normal again.

To prevent renewed gathering of dust between fan & heatsink, mount fine screen between fan and case openings.

I thought I had a similar problem with my D830, but my computer powered up normally, except that the screen remained backlit only, no Windows window! But I knew that it powered up normally otherwise, because, luckily, I had the Intel network gizmo controlling my Internet connection, not Windows, and it makes a beep once it connects to the Internet. Therefore I just knew that everything worked as it should, except for something wrong with the monitor. I googled the issue and found a site where a guy was doing something called a reflow, where possible, and if that didn't work, he would replace the BGA chip. Check out this Youtube video:

In the meantime, something Twilight-Zone-like happened to me and my problem: I bought a used, half-decrepit monitor at a thrift store and plugged it up to the D830. I did the chores (anti-virus update) and then went online to download any new firmware for the HP v17 (the external monitor), and while I was monkeying around with this, my D830 screen came on! I had tried to start it cold a few times after it had crashed, but without luck. Somehow, just having that external monitor helped my laptop-lid monitor to "recircuit" itself (about like recircuiting the brain after a stroke?), and so far it seems to be working just fine again. In the meantime, the HP v17 no longer picks up the input signal, so it immediately wants to go into sleep mode! I'm gonna unplug desktop monitor and plug in the HP v17 and see if it works, and if it does, I'll keep it in case my D830 gets another "stroke"!

I hope that this might be helpful to the next person who lands here (Francis has probably solved the problem one way or another)!

The dude

Welp, the HP v17 works just hunky-dory (hunkey-dorey?)! So I guess that the D830 doesn't like running the external monitor when its lid-monitor is running optimally. I guess! Actually, I'm clueless, but I'm gonna keep the HP monitor just in case the thing starts acting up again. I even have it "jacked up" on ketchup bottle lids to lift it about 3/4 inch off the surface, and still it may have hotted up (that's what I'm thinking is the problem). I used to turn off the screen, but then it would get persnickety and not even reawaken (I have it set to never-never-never (hibernate, ditten or datten)).
