    The keys were working just now, everything was ok suddenly they stopped working (2 wsx and caps lock) what could be the reason? The rest works fine, I just played and didn't press these keys anyway. I spend a lot on keyboards because I get bored quickly. Help me, what can I do now, I'm not going to buy another one, it suited me, only these 5 buttons.

    My keyboard is:
    EASY TOUCH ET-392

    As I wrote, they suddenly stopped working, I cleaned and the effect is still the same; /

    At 99 percent, you have a track burnout on the keyboard tape.

    You can, but it will be hard. You have copper tracks (a bit thicker than a hair covered in foil) so decide for yourself if you can connect it, but first check if it is this fault!

    Maybe my hint will be wrong, but better buy a new keyboard :)

    right; P recently summing up the expenses for harpsichord will be a little over 400 zlotys; / ... that's why I would like to try it above someone mentioned that maybe it is not the fault of this hair, etc. :|

    That's what this row is about and that's what the path points to, it doesn't have to be burned, it can be cracked. But that's the way it is good to check under a magnifying glass. I was repairing mine under a technical microscope.

    The right one is in the middle - I guess you can see the dusty paths? There are probably clean insulating foils on the top and bottom.

    I have 3 foils, the middle one is clean without anything and the other two have these lines like this; P and I don't know now; /

    You can see different designs, or I forgot what it looks like because I haven't taken the keyboard apart for a long time :D . If there are tracks on two foils, then you only have to get a good magnifying glass and look for a break or do it with an ohmmeter. If you locate the break, it would have to be connected with some conductive glue, for obvious reasons it cannot be soldered!
    You know where to look, because you gave it yourself -> (2 wsx and caps lock).

    still check the cable
    Dude, a few specific keys (2 wsx and caps lock) don't work, so there's nothing to look for in the cable! Read with understanding and don't put rubbish in!

    The keyboard in question, ie Easy Touch ET-392, costs 15 - 35 PLN. Keyboard damage most often occurs as a result of the appearance of a defect in the conductive tracks (usually graphite), the repair of which is possible with the use of, for example, conductive glue, which, however, costs about PLN 20. Repairing this keyboard can really be wasteful ...

    Hello, I will warm up the topic a bit. It looks a bit different for me. at the beginning caps lock was not always turned on with num lock turned on, then even when turned off, it was hard to surprise in parallel, the bi key stopped working, so until yesterday today it does not work for me left right down arrow 0 numeric keypad and, (del). Even before this post was written, it was working, not next to me. What could it be? MICROSOFT Comfort Curve Keyboard 2000

    note a new symptom: nm keys, arrows are back to life ... and the b key works when pressed hard and with num lock off

    What is going on?

    Hello, I have the same problem with this keyboard, except that 5.6, ctrl, and some multimedia keys do not work for me.
    For people who think that the problem lies on the side of the foil paths, they are wrong, because I have a way to deal with this problem, but from time to time you have to repeat it, the process lasts max 30 sec to 1 min without disassembling, if you already have the harness open, heating takes max 10, 15 sec and all buttons work.
    It is enough to heat the upper right side of the keyboard with the dryer, where there is the inscription easy touch and these 3 LEDs and the keyboard still works, in my opinion the problem is in the contacts replacing the tin on the board should solve the problem permanently but unfortunately I have to get soldering irons first and you can try.
    If someone gets bored, he can try to replace the tin, if he has 99% tools, it will work like new without heating, who will try this method, let him write if the method works.

    I am surprised but this method with the dryer really works (at least in my case the keys: q, w, e, r, u, i, op did not work) It's been a while but thank you for your help ;)

    I also confirm the effectiveness of this innovative drying method after reading the post by NYGGASA I applied it on a worn-out HP NX 7300 was the same symptom a few keys stopped working ... I heated it again from the bottom in the place of this key and now they all work.
    In fact, removing the keyboard is not a big deal, but I wonder if it will also work without pulling out and heating it from above.
    I hurried up and now I will not test it anymore, but if someone does not want to twist the keyboard, he can check drying from the top.

    I was just looking for a keyboard for my Lenovo Y580 (the "a" and "s" keys suddenly stopped working) when I tried the "DRYER" method. Less than two minutes of drying from the top all over the keyboard on the full power of the dryer, without unscrewing the handle and without removing the keys, and a miracle. Everything works as it should. Great respect for knowledge! best regards

    >>17459792 I am aware that we are in 2024, but maybe someone else can help. I have a Lenovo laptop and also have a problem with the keys on the S and X 2. Will a hairdryer do the trick? Or not to take the risk? Laptop bought in 2022 if it matters.

    Well, I am trying to fix the 2wsx keys on my laptop. I purchased a new keyboard and after replacing them on the new one, they don't work either. Where to look for the problem?

Topic summary

The discussion revolves around the malfunction of specific keys (2, WSX, and Caps Lock) on the EASY TOUCH ET-392 keyboard. Users suggest that the issue may stem from a burnout or crack in the conductive tracks of the keyboard's internal foil layers. Repair options include using conductive glue to reconnect damaged tracks, although this requires careful inspection with a magnifying glass or ohmmeter. Some users recommend a temporary fix by applying heat with a hairdryer to the affected area, which has reportedly restored functionality for various keys in other keyboard models. The cost of the EASY TOUCH ET-392 is relatively low, leading to mixed opinions on whether to repair or replace the keyboard.
