Greetings dear keyboard enthusiasts,

This is my first post, I am new to the scene, never knew there was a keyboard community until now, wow.
I was offered this old mechanical keyboard with a 5-pin DIN connector, and since I had no pc with this input I've ordered a ps/2 adapter from China.
I booted up the pc and I got this error message in the bios saying there's no keyboard connected. Restarted the pc, nothing changes, no lights on the keyboard show up, is it dead?
I opened it up and took a few pictures...
Started cleaning it up, was full off dust, also wanted to retrobright it, however I can't find liquid hydrogen peroxide in my country , however I am afraid I am wasting time. Don't have soldering iron tools nor experience, but would be willing to learn if there's some component broken and someone can point me up in the right direction.

Thank you for your time.
Best regards,
virtual

The keyboard's acting dead when connected to a PS/2 port on your PC's motherboard (via adapter)? And is that Windows 98 you're running there?

Can you test the computer with another PS/2 keyboard? Could be the computer or the keyboard, see.

Yes, I am using another ps/2 keyboard and works fine, so it has to be the keyboard. Win98 it is

Fair enough. In that case: look for leaky capacitors. The purple thing beneath the LEDs in one of your pictures is a capacitor. They had a bad habit of going south and spilling their guts, back in the day.
