I just got 3 laptops from a yard sale and i got this (i think its a compaq or samponge) laptop modle 5200. i cant get the screen to turn on, but i think there is a fuse blown on the mother board. but any ways i would like to use this lcd screen if its good. Is there a way to test them? i have all the parts for the lcd screen too. For the 2 wires (white and pink) is that the power for the back light? If it is whats the voltage, and if not how could i just power it on to see if its good? I will post some numbers off the screen now....

sticker 3, a bar code is on it too:
N5SD619028118
Also here is the # on the inverter board for it:
71-520TR-H02
I think thats all the numbers.

2nd part
Here is my 2nd part of my post (was just over the 1000 letters limit)
I would love to use this lcd for my pc im useing now, a project for my ps2, or maybe get the laptop running ( i think its OLD though lol)
Also is there any thing else i should know or post for you guys?
I am a noob to lcd screens but have worked on stuff like pcs, ps2s (fix them), xbox, ect. (even stereos lol). So i do know some about electronics. I made my ps2 protable and would like a BIG screen for it lol. The 5 inch verge is kind of small, this about 14 inch would bring in the game LOL. I think thats all the info i can think of.
Thank You for any one that posts about this here.

Im back with some updates...
From the laptop's mother board there is a 40 connector (not all used) and that goes to another chip (not inverter board) that has 3 input connections from the mobo and has 2 out. The 3 input on the board are as follows:
7 white wires + brown pin 1 wire
10 yellow + green pin 1 wire
14 grey + blue pin 1 wire
On this board there is this printed on it:
71-520TZ-D01
For TFT SVGA
I should be able to use a VGA out from a pc to run this lcd right? Or do i need an adapter board to convert it?
From that board the 2 out put wires are to the lcd panel it self and one to the inverter.
to the lcd there is a 30 pin flat ribbion wire and to the inverter board there is a 10 pin.
I hope some one could advise me on my project.

If you do a search in these forums, or in fact the general Internet, you'll find the same question asked many times over. "Can I use my laptop LCD without the laptop?" The short answer is "no", the long answer is "there are thousands of different LCD panels and controller out there, the odds are very high that you will never find a controller that will work with that LCD, and if you do find one it'll be several hundred dollars."
Thanks a lot. Now what to do with it, sell it on ebay lol? Also is there any use for that inverter board. I would like to use it (i know its only about 1 amp). it has 10 wires in and 2 wires out (i know the input is dc and output is ac. Or should i throw it in with the lcd screen on ebay lol? Thanks agian. (wish i could of used it, i have heard of the big battle on the converter chips now, i googled it lol.)
Selling on ebay is the best bet for LCD panels. It's perfect for people who are trying to fix a specific laptop. That's what I would try.
Dang that was fast. Thanks agian.
Also what about this laptop, i dont even know who makes it. lol

OH in your profile it said your really good with electronics. Do you know much about the xbox and its psu? I have a dead one here (v1.2-1.5) and it needs a psu. i dont want to buy one for $30 so i would like to use a pc psu (atx of course) i have read that people did it with older xboxes (v1.0-1.1) but its a different connector.
To address one of the original questions, the white/pink wires are likely for the LCD backlight, and also likely at anywhere from 200-500 or so volts, which will bite hard so be careful. edit: also, the current is very low and the high voltage/low current/high frequency make it *very* hard to measure the voltage to the backlight tube. /edit
I have had several experiences where LCD displays were being tossed because they didn't come up... because the inverter for the backlight was out. If you are otherwise going to get rid of the computer, pull the display half apart so the LCD is more or less exposed and shine a flashlight through it or use bright ambient light... if the backlight is out and the LCD is okay, you have more options than if the reverse is true.
And if the screen works but you still don't want the computer and shipping to austin is cheap, you could always ship it here, for The Cause. 😀

I haven't tinkered with the Xbox but power is usually power, if you can find a pinout of the connector and build an adapter for the right voltages you should be OK.
However, $30 is actually a pretty good deal for a replacement part, it's hard to get a decent PC power supply for that much, plus you have to consider your time and the advantages of not having wire-spaghetti surrounding your Xbox.

Lol. i already read about doing that test (have a 10 million candel light here, could see through it great and still dead) and also i used my multimeter and there is nothing coming to the inverter board or the lcd it self. i think its a fuse, not sure. if you want the laptop or the lcd screen ill sell it cheap (remember i got it from a yard sale lol) its old so its also kind of heavy. there is a floppy drive in it, the battery and the cd-rom is missing. i used a 16v ibm power cord (it worked to power the laptop up lol) also if you want any more info just ask me. Oh and thanks agian (im starting to like this forum lol)
Oh and lol agian. ya i know that but would be kind of cool to have a "hacked" psu for my xbox, also im hard on cash right now. I was looking forward of puting my xbox and ps2 in a pc case together and mod the heck out of them both lol. I would also like to add some other systems in there too. (like the gba SP with a Huge lcd screen out lol, i know im dreaming but it dont hurt to dream right?)

How cool would it be to have a rack-mount system with a bunch of connectors for controllers, about 2 feet tall, with all the game boxes in it...
I fixed one of my old laptops once, the screen was dead; it turned out to be a tiny SMD resistor that was soldered onto the actual ribbon cable and got chipped off. I actually just repaired an old Radeon 9500 video card by finding a place where a component used to be, finding hi-res images of the board on the Internet and seeing what component was there, and finding a couple of tiny SMD resistors to substitute.
So if it's a missing component, you might be able to see where something was soldered but has fallen off. Also, fuses are not hard to recognize, and if you do a resistance test across it and it's not zero ohms then you can try replacing it with a piece of wire.

ya i would love to put all of them in a box with all the hookups and then install a battery to power any 1 system at a time and a screen so you can take it with you on camping trips or if your lucky like me and have a big car i could make a 12v adapter so i can run off the car's batt and recharge the batt in it. ( i have done this with a ps2 already, i called it the pps2 (portable playstation 2) not ps2p (the hand held some one made from a slim ps2, but very nice lol, i would of used a biger batt and had a ext power adapter, i dont like haveing dead stuff lol)).
lol im not a noob on the fuse deal (remember i fix ps2s a lot, they have the same type of fuses, about 14 total) i have searched the entire mobo for all the fuses, i found about 6 and all tested good. also i dont think any thing was chiped off, i could be wrong. i would still like to test the lcd to see if the back light works or some thing (so i dont sell a "untested, nonworking" lcd on ebay, i have 100% feed back, i dont want to mess that up.
Also i have a ton of stuff to get rid of, i dont know if im allowed to sell stuff on here or not but if soem one tells me that i can ill post a list of stuff i dont want any more...ill put one on now lol
Linksys router with ac adapter (looks nice and i had it working with no probs, (got that from a yard sale too lol)
missing:install cd (shouldnt need it any way, i didnt.
