Are you sure it's not a soldering issue? eDP cables failures are extremely rare unless you intentionally abuse them.

Yeah, you're right: after poking the PTHs thoroughly with a soldering iron it works flawlessly. Thanks a lot for the suggestion!

Got my kit somewhat working just now. My screen was working without backlight until I had an idea to drop some isopropyl alcohol on the chips (while running the laptop). It looks like if I drop alcohol on the chip on the right the backlight comes on and the picture is great. But after a while when the alcohol has evaporated the backlight goes out. Also the backlight control doesn't work.

I've tried cleaning the whole board with alcohol couple of times already, but at most the backlight has stayed on for about ~10min. If reapply some alcohol on the right side chip the backlight comes back on no problem.

Could the board just still be dirty?
Any thoughts?
Using Manjaro Linux as the OS. Could the backlight control not be working because of this?

Make sure you run dual display mode ('Dummy display' + FHD display). Because your alcohol contains a small amount of water, pouring it onto the adapter board injects voltage to the sense wire, triggering the backlight. This can happen only when backlight enable signal is not present, which means that the backlight for the LVDS display is not being told to turn on. Unless you fried something during the installation, that means that the LVDS display is not enabled in the OS.

Oops, didn't notice I had the dummy one disabled.
Now it works in the OS, but the backlight doesn't work during post. This means my sense wire is bad, right?

At one point during my install I had backlight but no picture, even during post. Does it mean that my sense wire _was_ connected at that time?

Anyway, thanks for the great kit and advice!

No. That means your computer was using Dummy display rather than the real FHD display. So, the sense wire wasn't connected that time.

I received my kit last week , mod done on my X230 and everything is working great !
Thanks alot Nitrocaster !

Just make sure you buy the exact model, not some 'compatible' one. NV125FHM-N62 looks just as good as LP125WF2-SPB4 and it's cheaper. I added a link to verified eBay listing.

Are you sure?
The (supposedly) NV125FHM-N62 pictures are from a Samsung LTN125HL02-302.
And further down it says: Package includeds 1x LCD SCREEN or compatible one.
Proper BOE confirmation and guarantee is required before buying!

I bought 3 screens from that seller and they turned out to be good. However, you always have to ask the seller for the exact model that you need.

Anyone have flicker issues when you move the screen? It works perfectly then I move the screen and it’ll flicker then artifact and go back to normal.

Screen finally arrived today so I'm going to solder my mod. The mod kit didn't come with an auxiliary power cable, just a sense wire. Can I use part of an old USB cable (which is stranded) or should I find a thin single core wire?

Whatever solderable (since some cheap cables aren't even copper these days) will work, i personally prefer a single core one (and butcher cat5 twisted pair patches for them).

That's a typical sign of display failure. Could you upload a video?

Ended up using single core. Soldering was quite stressful but it worked first time so

Now time to investigate putting osx on it, seems the fhd mod doesn't play nice with it.

Thanks nitrocaster, "credit to team"!

What happens if you slightly press on the bottom area of the bezel?

It turns pink and artifacts/flickers when i press the bottom left area of the bezel.

That's definitely a display failure. Sometimes displays get damaged during the shipping, sometimes the damage occurs when people handle them too rough.

Wonderful, thanks.

I finally got my conversion kit, but I'm a little afraid of installing it at this point... Is there a place in San Diego that can install it for me? I still need to order a screen and I'm not sure which model to go for.

What have I gotten myself into!

Or am I overthinking it and it's not too hard.

If you don't have any soldering experience, it's going to be very hard.

Regarding display choices, the very first post of this thread shows your options:

LG LP125WF2-SPB3 : matte, IPS
LG LP125WF2-SPB4 : matte, IPS
AUO B125HAN02.0 : matte, IPS - avoid (sometimes doesn't work with the kit when other displays work fine)
BOE NV125FHM-N62 : matte, IPS

I am looking for a kit. A new batch seems not in sight, so if anyone has one spare, feel free to drop a message.

Are new kits not going to be made? I signed up and am also hoping for one.

There probably will be, though not in a forseeable future from my humble understanding.

I filled the form something like 10 days ago and received the bill today ! paiement done ! waiting the board and gonna order the screen !
Thank you nitrocaster

You're a lucky man. I filled out the form 7 months ago and have not yet received any news from Nitrocaster.
I have at home the new screen... hope to receive news soon.
Enjoy

Hi guys,

Could you please advise what the difference between preferable screens is?

LG LP125WF2-SPB3 : matte, IPS
LG LP125WF2-SPB4 : matte, IPS
BOE NV125FHM-N62 : matte, IPS

I mean, how should I pick one, what are the criteria?
Thanks.

Good news! The 4th batch is in production now. Assembled PCBs are expected to be ready by September.

There's little to no difference as far as I know (and I've seen all 3). Just make sure to ask your seller for exact model (not 'compatible' or 'replacement') without dead/stuck pixels.
