What would be the best IPS screen for x230 with least ghosting/hotspot problem and how should I carefully recognize it when looking on online listings please? Neither of tested displays has this problem. Avoid AUO displays as there's a chance your display won't work with the kit. https://item.taoba...

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. There's little to no difference as far as I know (and I've seen...

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

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

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

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.

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

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.

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.

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?

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

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 tha...

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

Shipped 28 orders today.

And I have some good news. As you see, the order system we currently have just sucks. I'm setting up a web store which will track available stock and allow you to make a purchase right away. Once done, I'll post the link here.

The last thing I thought would be a problem is to get payments from people who placed pre-orders. I have about 70 kits ready for shipping and people just ignore their invoices. I'm not sure if that's their spam filters or just a passive way to say 'no, I'm not interested anymore'. Probably I should ...

Does this mean that 3.3V for the panel logic power comes directly from the laptop's 3.3V rail w/o any switches? By default, yes. 3.3V for panel logic is connected to VCC3M via a 3A fuse. There's a pair of empty pads just above the fuse on the adapter board, marked 'J1'. When you have the right firm...

@L29Ah: The panel is powered exactly same way as the stock one. The only difference is that VCC3P, which is used to power stock panel logic, is not used by default (although the adapter board is designed in such a way that it can power the FHD display logic from VCC3P). I'll post more info regarding...

Does that mean it's your 3rd B125HAN02.0? I experienced the same issue with botched serial transmission with the same display model which I got from one of local thinkpadders. And I returned my own B125HAN02.0 to local shop after it suddenly stopped working after about 6 months: it started to flicke...

I've been using B125HAN02.0 for some time and it worked just fine. Are you getting no image or no backlight?

Somebody mentioned this before, but I store sources for the guide on my desktop workstation which I currently can't use because of some issues with RAM. I made my board work, so I don't "demand" anything of you - but I think I was indeed entitled too. Just please change that tutorial sentence. I'll ...

We are back to the regular schedule! 28 orders shipped today. And it looks like I finally got a workaround to ship faster.

Probably the patch has to be fixed for compatibility with new Ubuntu LTS (or with the kernel itself).

Change your display configuration to enable only the FHD display (without using dummy display) and see what happens.
What is the model of your FHD display?

That has to be added to the guide along with a troubleshooting section.

I am not complaining but I completed the Google order around six months ago but have not received an order number or an ETA.

Could i please have an update?

Apologies if i have not read the Google spreadsheet correctly.

You're in the 4th batch and I haven't yet done dispatching the 3rd one.

@evening_hunger: You may want to look at a Toshiba DD0BLILC130 cable, it's 30-pin eDP and about 33cm long. https://www.chipbay.uk/product/toshiba-s50-s50-b-s55t-b5-s55-b-s55-c5274-l50-b-screen-ribbon-cable-dd0blilc130/ https://www.ebay.com/itm/282506950668 Don't know the pin-out of those.

In Linux I have some screen flickering (about 60 to 75 Hz) with kernel-fhd patch applied. And no flickering when using an patch-free standard Linux kernel. The only change is a kernel with an applied fhd patch (otherwise same kernel, same kernel config, same system). This is unfortunate because I g...

Received the kit, thanks. Unfortunately I'm not doing the job yet, I have a B133HAN04.6 and I think it has wrong connector location.

I noticed that long eDP cables are now available on AliExpress, so you may want to try getting one.

The new installation guide is now available: https://drive.google.com/file/d/1FyGTmiLmdiJ5kYUtfP8SM-Hy2erFvHTQ I also updated the link in the first post. upd: It is still not perfect: some pictures refer to rev.4 and rev.3 boards and some are just taken from the Internet. Application notes don't tel...

52 orders shipped today.

Took my second X230 and kit to a pro to try to get that working, and having a weird combo of problems. Original one had new lines run to replace where I desoldered, and we're back to flickering or no display at higher resolutions, so I'm guessing that something was off on that machine to begin with...

@nictrocaster: Could you post the part number of the FPC cable connector? I broke off the black latch so I want to order one and see if I can replace the latch. It's FH19-28S-0.5SH . It seems quality for that connector went down from rev 3 to 4. I had 2 pins sticking out of the gate, no way to put ...
