Quote from: Moschops on Mon, 15 September 2014, 12:34:16 With apologies for going off-topic, it's really annoying me that the W and X keys don't do anything. I'll never use it as typing on it is horrible, but it's still a keyboard and if I could fix it I'm sure I'd find someone who'd like a glowy-blue keyboard with extra buttons. I'm going to take a good look at the membranes (given how they work, I could imagine that if one conductive path was broken somewhere, it might affect very few keys, and that break might be nowhere near the affected key), but if anyone has any ideas I'm listening

Think it is pretty hard to fix a membrane unless you want to fully replace it



It's easier than you might think. I've done it plenty of times with my previous keyboards.After spilling liquids, upon opening them up, I would see a discoloured trace that was interrupted if measured with a tester (mostly when someone did this and left it plugged in a long time after the spill).I always fix them with what we call here "silver paint" or "graphite paint".The closest I can find on amazon are these (search keywords: "conductive pcb repair"):But I don't have those here. Instead, we have these here in Argentina (south america), which I have used many times:The Conductive paints based on silver are more expensive but the resulting resistance in Ohms is lower (which is good). On the other hand, the conductive paints based on graphite are much cheaper, but their resulting resistance is higher (not so good. Graphite is only good for signal traces, like keys, but bad for lighting an LED that feeds its power through that repaired trace).Use a multimeter/tester to test conductivity of the traces in the membrane that you suspect are faulty. Be careful though, the multimeter probes are pointy and may scratch the membrane traces and damage them if you press too hard and loose grip of the probes.My guess is that the pad below the W key could use some of that conductive paint.Beware, it is kind of an art. Practice practice practice. Try it first on a piece of paper, then measure with the multimeter in the piece of paper. Sometimes a couple of layers with drying time in between give the best results for low resistance (low Ohms means that more current can go through that trace: less interrupted).Hope it helped!Cheers!!.KeyHopper.EDIT: fixed syntax/grammar. Added recomendations at the end.
