Thank you so much for this article! Very helpful!
I need to purchase a replacement screen. I am in South Africa and will need to import. I however do not know what sites to trust and where I can buy from. Would you be able to send me a link to a trusted supplier? Apon removing the screen the code is as follow: LP171WU1 17.0″ WUXGA

In reply to Shomir. @ Shomir, This is not inverter related failure, that's for sure. Most likely this is LCD failure and it has to be replaced. You should be able to find a new replacement screen on Amazon. I recommend buying one with the inverter attached. This will help you to avoid screen-inverter compatibility issues.

I have an Inspiron E1705 that has developed vertical Gray bands on the screen. At first there was one and then 2 and now 3. The bands are about 1 inch wide and run vertically from top to bottom. They are about an inch apart. I connected the lap top to a TV and there were no bands so I am assuming that there is a problem with the LCD screen or the Inverter or both. Could you please advise me what I should do? Also, where can I find replacement screen+inverter – from DELL? The screen is the 17″ Ultrasharp Truelife Widescreen WUXGA I believe by Philips.

The problem with this laptop – Dell Inspiron 9400 – Core 2 Duo T7200 and frequency must be 2 GHz, 998 MHz, but really with a multiplier x6 … flashed the BIOS with the latest firmware site Dell – A10 useless. Thought – change the frequency of loading, although this thing in the BIOS and disabled. Run CPU-Z or there AIDA, run hard test, or archive WinRAR – frequency should jump – but not, as it was in the area of â€‹â€‹998 MHz, and remains …

What is the problem and what to do?

In reply to Leandro. @ Leandro, Probably you can turn the display 180 degrees (if the length of the video cable allows that) but I don't think you can mount the display to the laptop body this way. The only way to figure out is to try it. By the way, check out my photo frame project. I used an old laptop to make a picture frame. You can easily use this frame as a kitchen computer with a USB keyboard and mouse.

@IML Tech, not only upside down, but with the screen facing backwards, like in this image: http://bluelinecity.com/wp-content/uploads/1238254977469.jpg

Anyway, you’ve given me the courage to try, thanks!

In reply to Leandro. @ Leandro,

Having had the experience of disassembling the display on this model, do you think itâ€s possible to mount it backwards for the purposes of the link above?

Do you mean mount it upside down? Yes you can.

Hi!

I was planning to take my old Dell Inspiron 9400 and repurpose it for this: http://bluelinecity.com/projects/kitchenet/

Thanks!

I have an Inspiron 9400. I installed a new screen using your instructions. Worked GREAT!

My Inspiron 9400 has developed the pink problem, so I replaced just the screen (not the inverter) and it didn’t fix the problems – still color problems but they are a little different on the new screen (e.g., lots of green where black should be, but still some pink too). Does this mean the problem is just with the inverter, and do you think I can only replace it (keeping my old screen) and fix the problem?

My new screen came on its own in a different casing than my old one, so from the old one I had to detach the inverter board by unscrewing the two tiny screws that were attaching the metal strip (with the inverter board) onto the old casing. Then I just taped the inverter board onto the new casing, since there were not similar screw holes on the new casing. It worked as well as it could, and I could have closed it back up, but I think I need a new inverter.

Thanks for the directions regardless – very helpful!
