Alright, so here's the scoop,
im not as good as i'd like to think with electronics...

I have an old 700mhz IBM Netvista Computer:

I want to take the LCD and turn it into a standalone monitor.

It's already disassembled, and ready to go...i just have to figure out how to do so.

I have the inverter as well.

I can take some shots of the hardware if needed.

Please help. i want to use this :)
 
Yes, please post pics.

At first glance, you may have problems, since the interface is probably proprietary to IBM. You might want to see what you can find about its specifications. The LCD FAQ isn't too optimistic.
 
Okay, strip the LCD down to the bare LCD and nothing more. You should see the metal frame and interface cable and such. Find out the manufacturer and model, then post it here and we can see what could work.

I'm going through a similar process right now, so here's a heads-up. You will need to find the datasheet for your LCD, then check for compatibility with a suitable LCD controller board which has the VGA or DVI input you want. You might also need an inverter board for your backlight. Finally, you will have to sort out the power supply, enclosure, and wiring. Right now I'm at the wiring process, and so far it's been difficult to find a contractor who will do a one-off job like this.
 
The LCD is connected with PanelLink Receiver SiI 151B and TDK inverter.
It compliant with DVI 1.0 (20 pins)
(DVI is backwards compatible with VESA® P&DTM and DFP)


Here's the Inverter. Its manufactured by TDK.

Here's ther screen itself. It's Manufactured By Hyundai.

Heres the LCD controller. Manufactured by Silicon Image.

And last but not least. Here's me all stressed. :)

I do have access to some breadboard and a saudering iron, and other such equipment if needed. Im hoping to place this in the side of my case :). Thanks for your replies!
 
Now look on the LCD itself and try to find the model number. The model number will be something like HT15X15-D00 or something to that effect.
 
Hey, im at work right now, but thanks for your help so far, i'll post the model number when i get home tonight. prolly around 7pm est.

LOL i deal with computers at work, and at home...and still have time for my girlfriend...how do i do it?

Also, the computer has a powersupply that came with it, that i belive has the power cable to power the inverter, so i think i have the power supply handled.

Main thing im worried about is what cable to use to route the display to my video card.

I have access to some dvi extentions here at work, and i can see if i can get my hands on one.

but the inverter is good, and the screen and everything functions, i tested it all before i removed it.

anyways, im out.
 
Digital View has everything you would possibly need if you had the -200 model. It's fairly likely that your -100 model is supported as well.

Select the Hyundai HT15X11-200 here:

http://www.digitalview.com/controllers/csg.php

and you'll see a complete listing of everything you would need, all available for purchase from a Digital View reseller.

Otherwise, you could check out these controller boards which are confirmed to support the HT15X11-100:

However, they might lack all of the parts you will need to build a complete monitor.
 
Now im confused.

I read some other places that i could use the current hardware it has, and convert it to a 20 pin DVI.

No other hardware needed.

Im pretty sure it has all the nessecary hardware...
 
There is a panel on the back of the lcd that is manufactured by Silcon image,
It's the PanelLink Chipset.

Model Number: PWA-LP6641/RX BD
 
Okay, interesting new information then.

So here's the deal. The SiI 151B is the receiver chip for the Sil 150B transmitter chip located on your LCD panel. As the Sil 151B supports PanelLink, it also supports DVI-I through the 20-pin connector located on the same board.

I've been unable to find an authoritative pin assignment sheet that describes that 20-pin connector, but once we locate the datasheet for the SiI 151B chip, we can find out which pins on the SiI 151B correspond to which DVI-I pins on the connector. All that's required is carefully measuring continuity from the chip to the connector using a multimeter...

...but first, we'll need the datasheet for the SiI 151B. I found one source, but the site requires registration, and I'm currently waiting to get my password to access the datasheet.
 
dang man, nice find, thanks for your help,

Think i'd be able to splice the wires into a dvi extention cable?

If so, i may be abnle to get one :)
 
Sorry, nothing yet. All you need is the SiI 151B datasheet. I'll keep looking, but in the meantime perhaps you could try to find it too. Note that the part number is S-I-L 151B, not S-I-I. SiI = Silicon Imaging ;)
 
Okay, found a datasheet for a pin-compatible IC, the SiI 161A,

http://www.siliconimage.com/docs/SiI-DS-0055.pdf

Okay, page 1 has the pin diagram. Let's focus on the area labeled "Differential Signal." Now trace the pins in this section to the pins on the board by probing for continuity using your multimeter.

Once you know the pin assignments of the 20-pin connector, you can easily point these pins to appropriate pin locations on the DVI connector,

The only thing I'm unsure about are pins 6, 7, 16, and 22 on the DVI connector. Perhaps someone else can chime in about these :eek:
 
Just curious to know how it's turning out!

I have an old IBM laptop too and was thinking of doing the same thing.

Having any luck?
 
Well, its still a WIP.

Been on the back burner for a bit, but its making its way back up.

Unfortunatly, this is out of a netvista desktop.
if it has the same controller chip, it may work.

Got a buddy of mine trying to figure out the pinmaps at the moment.

Kinda complicated, but we found some good resources.

Hopefully more to come soon, so keep watching!
 
Howdy all. I'm the guy who inherited this doodad. After downloading the PDF for the SiI151 datasheet I have been able to definately determine 12 of the 20 pins. there is one that I know how it connects but I don't know what it is for on the DFP cable. At any rate, I have posted my progress at: http://www.gennon.net/projects/vistalcd

The pin that I don't know what is for is called PDO (Output Driver Power Down). It is an input pin and is part of the power management So far the DFP pins I haven't used are (7)GND, (8)+5v, (9)NC, (10)NC, (14)SHLD0, (17)NC, (19)DDC_DAT, and (20)DDC_CLK. Perhaps someone knows which one corresponds with PDO.

The description for the PDO pin on the IC as per the datasheet (note SCDT(SiI151) is HPD(DFP)):
Output Driver Pwer Down (active low). A high level indicates normal operation. A low level puts all the output drivers only (except SCDT and CTL1) into a high impedance (tri-state) mode. A weak internal pull-down mode with this pin.
There is an internal pull-up resistor that defaults the chip to normal operation if left unconnected. SCDT and CTL1 are not tri-stated by this pin.


This this pin coming from the cable goes through a resistor and then connects directly to the IC.

At any rate. I'm making some progress. I don't have a multimeter to test the ground and +5v leads. If i make any more progress, I'll update.
