Hi Folks,
Please forgive if this has already been covered, but I have searched and read most of this long thread and learned much, but still have a few questions.
My aim is to make a poor man's Kindle -- ie a screen to read my downloads, books and pdfs in bed that is much lighter than the 15" awkward laptop that I'm using at present.
I used to print everything for bedtime reading, but my new $40 printer/scanner costs a fortune for the ink.
So my battered and black-screened Dell Inspiron 1720 got the screen removed and I was going to make an extension lead for the signal and lights to go back to the laptop keyboard that would rest on a shelf next to my bed, level with my head.
Seeing the myriad of minute wires in the connectors, I guessed that an extension lead would not be available ready-made (or would cost an arm and a leg) and soldering this minuscule multitude is beyond my tired old eyes.
So I looked at a 15" Samsung monitor dumped on me from my son's recent upgrade, and when I pulled this apart, the smaller screen, and 20 conductor ribbon that I would need to extend, sold me on this one.
I have two questions. First, looking at a Samsung website about care of LCDs, they mention not to pull or bend the power leads to the lights. Anyone know why? Oh, and there are four wires going to each lamp, two thick and two thin, and they seem to be quite independent sets, having their own sets of electronics. (?inverters?) I guess there would be no problem extending these by a meter or so with 4-core, 7x020, 2.2 amp security wire? Insulation??? Megger???
Second, how would 5 lengths of this same cable be for extending the twenty-wire ribbon? I could even strip the casing off them (in the middle only, to aid marking on the ends) and enclose them in spiral wrap...
The next trick after that will be an angle poise arm to support my "Kindle".
Any comments or problems raised will be much appreciated.
ps, Oh, the monitor gubbins will be kept under the laptop shelf and will be connected to the laptop above it with a standard VGA lead (DE-15M/DE-15M) Cheers, John

I have a LTN154P2-L04 15.4" WSXGA+ LCD display that i bought off a friend for 20 bucks, Ive looked for a controller that i can use with a DVI/HDMI input that I can use to display the native format of the screen with. From my searches the best i have found are controllers on www.LCDparts.net does anyone think that these would work?

There is a suitable controller on ebay here:
http://cgi.ebay.com/Compatible-R-RM5451-LCD-Controller-Board-Kit-DVI-/270658532961?pt=COMP_EN_Networking_Components&hash=item3f04817661
It has DVI and VGA input and supports the resolution of your screen. Ask the seller if your particular panel model is supported before you buy. It looks like the power supply is no longer included in the kit. May want to ask that too...
I have not yet seen a controller with HDMI input.

Argh I'm going to miss the close date on that controller - any ideas where I can look for a controller similar or where else to buy that one?
p.s
http://lcdparts.net/LCDC.aspx at the bottom of the page there is one with an HDMI input.

I'm sure the seller will re-list the controller. ;-)

If you get the controller that we've been talking about, you don't need to know the pin-out. Tell the seller what panel you want to use it with and they will ship it with the correct cable.
Or do you want to build your own controller?

If I cannot build it, I will buy the controller. Which is the price of the controller? I am from Spain... I hope the shipping wont be to expensive... :P

The listing is in US$ and the seller is in China. Open your Spanish ebay and search for item number 270674575348. This should show you the item price and postage cost in Euros under the US$ price. These are estimated prices and might be slightly different when you buy, depending on exchange rate.

Honestly,I'm not such experienced in electronics,put let's try this one out,it might be even fun :)). what do you think if we just took an ordinary desktop monitor,chop the case of desktop and fit it nicely there?of course, the monitor must be very slim, and the chop made on the other side of the unit,not on the one with the PC components next to it :))). I think that with a few adjustments, it might turn out something cool.Anyway, i expect you'r opinions :D

Just a theory...
Perhaps a digital camera could be utilised as an analogue to digital converter. They take pictures in analogue and then convert them so obviously there is some form of hardware converter within.
Any thoughts?

Hi,
I have been looking for a way to add a DVI input port to my laptop so that i am able to watch tv and play xbox360/ps3 on my laptop monitor. (i travel alot and as you may know DVI inputs on laptops are scarse)
i stumbled upon this thread and i see a possible solution for adding these controllers with DVI input that are discussed here.
i am somewhat familiar with electronics but i am no wizkid on the matter and i was wondering if anyone here has some experience with this or can give me any advice?
One question that i have about this controller:
I wish to be able to switch between the DVI input (from the TV etc.) and the video input from the onboard laptop gpu/mainboard. Is this possible?
EDIT: so that it is clear basically i want to combine two inputs (GPU on laptop & TV/XBOX/PS3) into one output (to LCD).
thx for any help you can give me

This is quite easy to do with "all in one pc's". However laptops seem trickier.
With "all in one pc's" the solution is to use the pc mainboard as the decoder, strip the mainboard down to a bare board so it can't boot, but it can turn on (ram, hard drive, all expansions slots, fans, the lot)
This means when the pc is turnen on, only the monitor and mainboard turn on. Since the mainboard has nothing to boot, it will just hang and if was connected to a monitor, would display a failure to boot message. However, the monitor is connected elsewhere and mainboard is only being used as a means to switch on the monitor and to decode the signal.
Then all you need to do is redirect the graphics input, which should go into the mainboard where it is decoded, quite a simple solution but only applicable to all in ones pc's that use a standard AGP or PCI-e graphics card
Edit: After doing some research it seems that there are two types of "all in one pc". One type are basically laptops without a folding screen that is attached to the back instead. The other are basically altered desktops pc's crammed into a tight space with standard ram, standard PCI and a standard PCI-e slot when you crack the case open. Obviously it's the second type you need as it's the standard graphics slot that makes the monitor able to be stand alone (by tracing the cable back you can see where the graphics goes into the mainboard (which is the decoded and the signal is passed on to the monitor)

Wow this is exactly what Ive been looking for! I started reading this post, then realized how long it was...I think this is an awesome topic and a great way to save money. I just took apart a broken dell inspiron but the screen is still in fine condition. Has anyone found an easy way to hook it to a desktop without spending a lot of money or tons of tedious work? There are 21 wires total coming out of the screen, some of them from the screen and some from a circuit right beneath the screen...the power? Anyway, is there a simple way to do this? Sorry if this has already been answered, but i think it has mostly been explained in fairly...high-tech-ish manner....Thanks guys you are all brilliant!
As in afterthought...if i miscounted and there are 20 wires, is there a way to just plug the screen directly into a DFP port if i somehow rig the wire correctly?

I was just thinking of doing something very similar. I have a sharp lq141f1lh52 14.1" lcd screen from an old laptop someone busted and gave me. I'm looking to turn it into a monitor of sorts. Just need help figuring out the pinout for it.
What I'm hoping to do is turn it into a monitor that not only has the option to hook into your pc for another screen but also has video input ywr to be able to hook a vcr, gaming console etc into.
any help would be greatly appreciated.

Hello, I've been following the steps of this thread to achieve the goal described in the title.
I decided to turn my old laptop's lcd to a TV as I thought about using it on an old ps2 console.
So I've made it to a fine point but now I'm facing some weird trouble.
First of all, my laptops lcd name is : N154l2 - L02 Rev.C1
I purchased this controller: "R.RT6251 LCD Controller Board/Card Kit(TV/PC/DVD) DIY"
from ebay seller : njytouch (if you search the item on ebay it will popup first)
I've got everything set up correctly, checked up cables are properly connected.
Then I turned it on and checked that it works ok. Meaning the screen turned on and showed stuff.
I could also switch through the input channels as you can see in these two pictures:
Now when I try to plug in some input, av, vga, tv antenna or s-video I get this distorted image:
And then if I unplug the input the screen stays distorted showing no signal again.
Then I have to turn it off and on again in order to get rid of the distortion.
This is really frustrating as I was almost done here and all I get is this.
Does anybody have any idea of what could I possibly be doing wrong?
Did anybody face the same problem? Any help would be highly appreciated!

one of the buttons on the controller does auto config when you press it. Can't remember which button. Try that when you get the distorted signal.
also, what resolution and refresh rate is the output on the computer set to? it might be too high resolution for the controller/display or too high refresh rate...
