Single to Dual Lamp

I'm looking for some input about modding an inverter.

User kaltmond said that he got two inverters, cut his wires, doubled them (to have a pair for each inverter), and that's pretty much it. The rest is plug and play.

Since I'll have to find two sets of inverters and cables (and it would be quite of a mess), I decided to get just an inverter, from a laptop that already has 2CCFL display. I got MPV5K003 from a Vaio (found it cheap). It fits perfectly under the display (although it's twice as large), but it has 6 pins. Here's the problem. The inverter already sits more than a month in a repair guy, who says that it wont be easy to mod it. That's why I'm asking you, would it work properly if it's modded like this:

EDIT: What I mean is to solder my connector on the Vaio's inverter board.



Mine/Vaio

Greens are 1:1
Yellow is non existent
Red has to be split/doubled, whatever

Here are the pin-outs:

AS0231701H0 (my inverter)
1-479-137-13MSS (alternative to MPV5K003, supports the same models laptops, so it has the be the same)

For anyone who is looking for quality upgrade (there aren't too many 16:10 15,4" Single LVDS left, but still), here is the screen I'm using: LTN154XB-L01. It was a hard time to choose either this (90%) or N154I4-L04 (72%, better viewing angles, faster response), but the Samsung came cheaper, so

It's currently running on Single Lamp, but compared to my old LTN154AT01-001, the difference is mind blowing

Let me know what do you guys think, as the second CCFL is there for a reason

 

Hm well you have the pinouts right? whats stopping you from using the dual backlight?

 

Well it seems that the repairman is way too lazy or way too greed and wonders how to charge me huge amount for a simple soldering like this. I called him yesterday to return my both inverters, and: option 1 - I'll search for another one; option 2 - I'll start buying soldering equipment, as I definitely want to make other mods as well. Seeing how "enthusiastic" is everyone I've asked so far, I better choose the second option. Among 10 people I asked (laptop repair guys), most of them said they are busy, some say it's impossible and etc... Whaaa', it's like I'm not their client! Any recommendations about soldering tools, heat guns (blowers?), "vacuums" (I don't know how it's called), or combined heat-guns-(blowers?)-"vacuums" and so on?

 

C'mon guys. There are plenty of you who do soldering. I know it's not an easy task (not at all), but I have no other options And as I said, I have some other ideas as well, so it would be handy to learn how to solder (have two MoBos for trial and error )

 

I solder and am willing to help.

First i have a few questions. Why are you doing this mod and is this mod for an Acer 5920G if so I'd really like to know whats up cause you know i like upgrading mine too. Secondly are saying it possible to more power from the Inverter power source, if so I could benefit from this knowledge i need DC power for a cooling mod i'm cooking up.

Okay I have been practicing soldering a for a while now. I am no Jedi master but, I am an Educated young Padawan.

I solder with a cheap SMD reword station my boss got off ebay for like 80bucks usd. It has a heating iron and soldering iron. Now that i know what i'm doing and there is an entire science to it the the heat iron is an amazing piece of equipment for reviving dead gfx cards, thats the reason i have an Acer 5920G.



How ever you can save even more more money and just get a soldering iron station (half the size and just the iron part [no heating iron])



It doesn't have to be any thing fancy. All the maters is it is clean and taken care of properly, i can get in to more detail on what and what not to do if you choose to buy some equipment.

I do hear a brand called "Hako" or American Hako is a decent brand and happens to be what brand of tips i use, assuming they aren't Chinese counter fits.

As to what kind of tips to get, get package with with several kinds. I will be honest and say i use just one tip, I don't know what it's called but, it's kind of flat and somewhat big. I find it does the job perfectly even where i might need a needle tip, i just use this big ol' fat tip and take good care of it and tin it according to size of joint i'm dealing with.

There are perks to soldering. I scored a 45 dollar graphics card not to long ago for the price of 3 vrms (3.00 usd)

NV GTS250 replacment VRMs (SUCCESS)

So yeah let me know, i'm no expert but, i know enough to make a decent joint and what equipment to use for the most part.

 

First of all, thank you for the input, it's greatly appreciated

Congrats for the reviving of the GTS250.

It's for 5920G, yes, and I'm currently running Samsung LTN154XB-L01 on a single lamp and as I said, it looks gorgeous. I'm looking at the schematics in order to put some more wires for a higher res one, but that's another topic

According to what kaltmond told me, it's not a problem to draw more power from there (he is using two inverters, wired to the standard cable).

Thanks for the suggestion, first one would do the trick, as I don't need anything fancy, just something to do a few mods, but I'll probably need a heating iron as well. Found this KADA 852D+, is it the same? Comes with some free stuff as well as the shipping I think that they would do the job for a beginner like me.

 

Yup that's it and not too bad of a price either. Can't comment much on the soldering iron tips, can't see them to well but, hopefully one of them will work for what you need.

I will also be more than happy to tell you how to TIN then and take care of them in such a way they actually last and conduct heat.

I can also teach you some really useful methods with the heating iron part but, you will need aluminum foil and a space heater.

 

There is a good guide in my sig...

 

That guide has some issues and few tips aimed towards radios which ie Silver solder is best for PCs due to the heat generated as an example. I especially know the tips like wiping the iron off on a sponge between joints is BAD.

I used to do things just like in that guide till by boss and another tech found a VERY interesting write up (which i'm sure they lost) about how stuff like that can wear out the tip quicker.

I found by reading write ups like they found i can make tips last REALLY long even under maximum temp.

food for thought. I will make no promises but, i'll ask and see if there isn't some slim chance i can find that write up.

 

@whitrzac - That's a really nice guide, I got half-way so far.

@cdoublejj - Throw'em in, it would be useful for me, as well as for someone else, just getting into soldering
