2000-0146 error indicates DST Log contains a previous error which refers to previous errors in the hard drive which might not really be a hardware failure. In order to confirm this, I recommend you to run a custom test on the Hard drive.
Restart the computer and press F12 to enter the Boot Menu.
Express Test: Performs a quick test of devices. The test typically takes 10 to 20 minutes and requires no interaction on your part
Extended Test: Performs a thorough check of devices. The test typically takes 1 hour or more and requires you to answer questions periodically
Custom Test: Tests a specific device. You can customize the tests to be run.
Symptom Tree: Allows you to select tests based on a symptom of the problem you are experiencing.
Select Custome test and then run diagnostics on Hard drive.
When you have finished running a test, close the screen to return to the Main Menu screen. To exit the Dell Diagnostics and reboot the computer, close the Main Menu screen
Please make a note of the error message.
Also, regarding the LCD blank display we need to replace the LCD kit as the display on the external monitor is working fine.
Awaiting your response!
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)!
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)).
