Hello there. This is my first Instructable

A while back I was sitting around and wondering what to do with my dead laptop. I knew the mother board was fried but everything else was still in working condition. As a result, I decided to make an external monitor from my dead laptop and proceeded to do the research to find out if this was possible. Below is what I discovered. Unfortunately, there was no way to use the motherboard's VGA connector. The VGA connector on a laptop is used to connect to an external monitor. In any case the VGA connector is output only and wouldn't work for an external screen. As a result, I found that I needed to buy a controller board for the LCD screen, to make it work as an external monitor. This was the main cost but was still less than half the cost of buying an external monitor.

The controller board cost me about $42 not including tax and shipping. However, there are various types that cost less.

I also built a stand for the LCD panel but as you will see, I decided to go a different route.

The information below will illustrate the steps I took to convert my laptop LCD screen into an external monitor.

Step 1: Getting Started

Lets get started.

Materials needed::
Dead Laptop hopefully with a good and working LCD screen.
LCD controller board
Hobby electronics screwdriver
wire cutters optional
5 inch section of wood 2x3
two 3 inch sections of wood
self tapping wood screws
cordless drill
drill bit for drilling metal
Dremel and cutting disk optional

Note: if your LCD is damaged then don't proceed any further. This instructable will not fix a damaged LCD screen!

Disclaimer: Due note, I take no responsibility for your actions, implied or otherwise. I am not telling you to do anything, This instructable is informational.

Step one. Unplug the dead laptop from any power source AND remove the battery!. The laptop battery is located, usually, on the bottom and can be removed by sliding a release lever. These are lithium ion batteries and can hold a few Amps. The risk of shock might be minimal. However, there is no need to take the risk.
I'm so glad I found this... I have a nearly identical HP laptop that you used and recently noticed that it was overheating and too much work to fix up, but the big beautiful display works great and I was sadly thinking I'd be better off selling it rather than dissecting the entire thing to fix its overheating issue. <br>Now I have a new use for it! <br>Thanks!
Actually, you can do One better. You can salvage the RAM, the Wireless card, the Batteries, the charger, the hard drive, the DVD disk player and sell them to people that need them on E-bay and Still keep the LCD screen for yourself. <br> <br>I suppose I should have made this Instructable on how to salvage your laptop. I'll have to wait till another one dies.
<p>Genius! As an honorary &quot;Red neck&quot; (U.K. chapter, it's a good thing, honest) I'm putting your application in the post. You have given me the three screens I need for my simpit plus a lot of peripherals that I hadn't even considered. Thanks.</p>
Very nice instructable. This instructable is the answer to a question that comes up about once a week in instructables questions and will get referred to often.
<p>Thanks so much for this! Now I can play around with another monitor!</p>
Where do you connect the power cables to. Is it attached psu?
<p>i can't find one for a macbook air screen (2013 11 inch </p>
<p>hii.</p><p>Thanks dot this cool guide, but i have something to ask about it-</p><p>I found a product called &quot;packed pixels&quot;, and i noticed that it can get its power from the laptop itself. How can i do it here? I want to use not just at home, but also on the move.</p>
<p>What power source can I use and how much power is needed ?</p>
<p>i have a Toshiba satellite m115 -s1061 model number is PSMB6U-00G005 it has a dead harddrive but the motherboard is good and so is everything else will it work?</p>
<p>i would love to be able to hook up my ps2 to the laptop screen</p>
<p>i would also like to keep it in the computer case</p>
so basically to sum up this whole tutorial: buy a controller board
I wish most tutorials would just say that I've really learned nothing.. no diy or salvage just an advertisement
<p>Hey there, new guy here. Got my hands on an old dell ultrabook which was not working, but I know that the monitor is still good and wanted to try out your project, but when I contacted the seller of the controller board they told me that they do not support this LCD. Could you help? This is the LCD I have (https://www.laptopscreen.com/English/screen-part-number/B133EW05~V.0/). From what I understand it uses a different connector.</p>
<p>push air from outlet to intake &lt; reverse flush &gt; dri air Works best</p><p>will give you back coller laptop</p>
<p>clean your cooling fan .</p><p>thats probaly your cheapest solution</p>
<p>Excellent tutorial!!!</p>
<p>I have a Mac desktop that I took apart. The Mac is dead, but not the screen. Will these instructions work on it?</p>
can i use normal lcd control board instead of LCD control Board...??
<p>Hi Guys,</p><p>This project looks great, but i need help in converting any laptop screen and only the screen into a TV. kindly help me on this guys.Thanks.</p>
<p>where we get the control board ? what is its name?</p>
<p>hi, is it possible to make a lcd monitor from old laptop screen that is powered by usb connected to your new laptop?</p>
<p>No. a USB does not provide enough power. Unless we're talking 5 inches LCD</p>
How does this work than https://www.kickstarter.com/projects/slidenjoy/slidenjoy-double-or-triple-your-screens. ??
Think this could be done with a monitor from a tablet PC that uses a Wacom digitizer?
<p>My guess is yes, but you would have fun finding a controller for the digitizer, and for the LCD.</p>
<p>@ThrowingChicken- did you every get an answer or direction on this?</p>
<p>nice DIY! congratulations. I have a question. I am not good at electonics. I found this LCD controller; http://www.ebay.com/itm/MT6820-B-5V-LCD-Monitor-Drive-Controller-Board-10-42-LVDS-Screen-Universal-IFA-/331559411398?pt=LH_DefaultDomain_0&amp;hash=item4d327b1ec6</p><p>am I looking at the right product? (let's suppose that it is suitable with my LCD). </p><p>Cheers!</p>
<p>I'm so going to try this! Everyone says oh, no you can't use that old screen for you tower. I knew that there had to be a way!</p>
http://pages.ebay.com/link/?nav=item.view&amp;id=271874639764&amp;alt=web. <br><br>Just like the laptop in the vid guys :D
<p>Good post. All good and I was curious also. </p><p>But I doubt you have a 3 million candela flashlight. lol. That's like 640,000 lumens or so assuming a 30 degree flashlight angle. <br>Even the most powerful flashlights are not that bright. Heck the high end ones are 10,000 lumens. </p><p>The huger spotlights they use in police helicopters are about 50,000 lumens.</p><p>Just saying.</p>
<p>Thanks buddy for for providing this useful information. I got most of my doubts cleared on converting a laptop LCD as ext monitor.</p>
<p>Any time. Glad i could help. Wish i had more time to post more but thanks for the feedback. Much appreciated. </p>
My laptop Compaq v6000 is dead (dead motherboard for). Is there anyway to still use the LCD? I'd like to hook it up to a DVD player Through AV Out socket ?
Yes look on ebay they have many different models that have different connections. But make sure you type in the model number/name before lcd controller board
<p>Just wondering if anyone can help, I have bought the controller board for this, its all connected to both pc and power. Turning it on my pc recognizes it and under 'screen resolution' it shows two displays available and i can set my laptop screen as primary just fine. But the screen wont display anything. If anyone can help that would be great! :) </p><p>p.s. if it helps the light on the control board with the power button blinks green for half a second or so, then sharp and quick red then repeats.</p>
It means its not getting enough power to display a picture. I have a screen as small as a 7in tablet that can be powered by usb but the one i salvaged from a laptop will just blink away like you described. It uses 12v so you either need to use a corded adapter or solder the wires to a 12v point on whatever youre using it for
<p>This is awesome. I have 3 working laptop screen salvaged from broken laptops!</p>
<p>This is helpful. I want to also use the keyboard and trackpad as external input devices as well so I basically can use my old broken laptop to controll my gaming desktop.</p>
It was simple. Thanks for the instructable. Very helpful!
<p>Thanks for the great instructable! I'm not sure if you'll respond to this since the last post was a year ago...<br>I completed the project, but my monitor is very dim...I've tried to adjust the brightness using the monitor's menu, but with no success...any ideas?</p>
<p>Just ordered the parts, going to set this screen under my glass desk as an easy to refer to code bible! thanks xD</p>
<p>Thanks man, worked a charm!</p>
<p>Something to try when my laptop completely dies. </p><p>For now, looking for a way to reuse the lcd screen I took out of a portable dvd player. (Horrible resolution, but might be good digital picture frame etc)</p>
Would this work for a desktop?
