Re: Smelly Epson KB03 keyboard - Any advice?

I'd first just try washing the back of the pcb with isopropyl alcohol, but given the amount of rust on that plate, I'm not sure it'll ever be properly nice without desoldering it, washing the pcb fully, wire brushing the plate down, repainting it then reassembling it. The flux used on old keyboards...

Smelly Epson KB03 keyboard - Any advice?

Hi all! If this is Not the correct thread to post this please let me know. https://i.imgur.com/fHDf12j.jpg I've just bought an old Epson KB03 keyboard and I realized that it has a weird smell similar to a plastic when its burned. Although the keyboard works great I'd like to remove that smell as muc...

Re: BTC dome with slider inconsistent tactility

I've bought a BTC 5140 recently and it's great so far, however the tactility is a bit inconsistent in some keys, for example, W is less tactile than T. Is this normal and is there a way to fix this? I can relate. I've bought a BTC 5149 and I came across the same problem. I've tried cleaning it insi...

Re: IDENTIFY THE KEYBOARD thread

I've just seen this in sale. According to the seller is a Datamax At/xt keyboard model 71018 but I can't find any information about it. The whole area next to arrow keys is really weird.

Do you know what kind of switches are these?

Re: Cleaned a keyboard and won't work now - Is this possible to fix ?

My idea with the lock lights was just a first-order check if the controller wasn't fried. It's by no means a true verification. But it leads me to think that it's likely a contact problem, either between membranes or from membranes to controller. Especially since none of the keys work. Have you cle...

Re: Cleaned a keyboard and won't work now - Is this possible to fix ?

Do the lock lights correspond to their respective state in the operating system? In other words, if you hook up a second keyboard and turn on Num Lock on that one, do both keyboard lock lights respond? Weezer is right, I've had trouble with getting good contact with edge connectors before. Also mak...

Re: Cleaned a keyboard and won't work now - Is this possible to fix ?

Looks like because the keyboard uses a pressure based "edge connector" that there's most likely a contact failure on that point. When you reassembled the keyboard, was it screwed down tightly? If it was, I would check to see if there's dirt or grease on the contacts on the PCB and membrane. As for ...

This is my Acer 6312 - T42 / SP / US which I bought a year ago for a really good price. https://i.imgur.com/43iEjBj.jpeg It was working fine But sometimes the left CNTRL key actioned randomly, and kept pressing for no reason, so I decided to dissassemble it and clean under the keycaps. Here is where...
