Possible to get longer 30-pin edp cable?

Anyone know if it's possible to buy a 30-pin eDP cable anywhere? I found a replacement LCD to go from TN to IPS, but the connector is on the other side of the LCD from where it is on the TN panel. Need an extra 100mm maybe.

 

Not unless they make it. And how did you confirm it was a replacement of the LCD?

 

These cables (eDP) are hard enough to come by, even less for the purpose you need it for. Even if you find one, most likely the motherboard end would differ.

 

I'm in a similar predicament. If those wires weren't so freaking tiny I'd attempt to cut, extend, solder and seal the cable myself. But that's likely a bad idea.

As an alternative, I was wondering if there's such a LCD cable as an eDP (30 pin) to LVDS (40 pin) LCD cable? Probably not.

There's no such cable - different signalling. At some point I think there was a conversion board, but good luck sticking it in a laptop. As for the manual cable extension, I've done that. It's all good if the wires aren't the coaxial type (with ground surrounding the data lane), if they are, fun times ahead (I've done that too). Don't forget to twist the pair after, or before the soldering, given it's a twisted pair in first place, if it's coaxial, it's not.

 

first of all I'm assuming you took TN screen out already, otherwise do so now, since when I was replacing my screen I was very confused: the MB connector was on left, and cable went inside right hinge so I thought screen connector was on the right, but new screen had connector on the left. Only after taking old screen out I realized original screen also had connector on the left and the cable was run long way around.
Also, on my computer, with little tinkering you could run cable through either hinge, maybe you could run your cable on the other side also, making the distance shorter and therefore being able to use original cable. You can buy cable all by itself, but the problem is the only cable that is 100 % guaranteed to work would be direct replacement for your computer and that one you already know is short. Buying longer cable for different computer may work, but as already some mentioned, connectors especially on MB may be different.

 

Well on a whim I bought the LCD, everything seemed to line up, connector fit, backlight came on, but no signal. So I guess it's not compatible. Thankfully laptopscreen.com will offer return/refund.

 

I know you already confirmed it didn't work but what if you bought another OEM eDP cable and combined the two in order to create a longer cable? However, this would require cutting, stripping, soldering and sealing the eDP cable.

Are the display connectors the same? If yes, they should be pin-to-pin matching. Most panels match, unless proprietary.

 

Yes, connectors are the same. Specs even say it's 2-lane eDP for current LCD. It plugs in just fine. Backlight comes on, but then turns off and no display. Stock is 1366x768 TN and new one is 1920x1080 IPS. Perhaps it's not truly 2-lane eDP. But I couldn't find a 1366x768 panel with same brackets, size, connector, etc. Maybe it needs a new cable that is actually 2-lane while current cable only supports 1-lane.

The physical size of this LCD seems to be oddball compared to other 11.6" LCD's, so it's been hard to find a match. Just hard to believe there isn't some IPS that matches out there. I'm fine with 1366x768.

To be honest, though, this is really more of a fun project. I have a couple laptops that I use regularly now, but this one is just a challenge for me I guess. I was able to upgrade a $220 laptop with about $120 worth of components (RAM, wi-fi AC, SSD, battery) and make it a great 10-hour battery laptop that outperforms any laptop significantly for under $350. Only thing lacking is a good LCD.

 

I guess it really is a single lane. Just like it was with LVDS beforehand, most laptops were shipped with a 1ch cables, and you were supposed to find or make a 2ch one, if you want an upgrade. You have to check if all the wires are in the cable in order to continue your project, to see where is the fault.

 

I did find a cable online and ordered it. Was only $8 shipped, so hopefully it will work, and should be plenty long to work with this. Crossing fingers.

 

Blind shooting is a bit risky. The display side should be the same, but the motherboard end, even if it's the same connector might be wired differently.

 

Yeah I know. I don't understand why this can't be commonized. It's a display, yet getting replacement cables can be impossible.

 

Some put the camera and mic, some only the camera, and third leave only the display lanes and run the camera and mic through separate connectors. Sometimes it's easier to make these non-display related stuff (camera (USB -> South Bridge/Hub), mic (codec)) with over the board cables, than routing them trough the better part of the motherboard in order to be accessed through a single connector. As always, I'm all for standardization, but usually it is hard to achieve, especially in proprietary machinery, what laptops are.
