Keyboard A4000 - Help

My A4000 is working great, now, only the keyboard needs to be fixed.

A lot of keys don't work. I open it, clean it, but still not ok.
For example the "a" key is not working, i try to make the contact between the 2 points with a wire, just to make sure it was not the key that was not pressing in the correct place, but it didn't work.

Any ideas in what to do?

I have an CDTV working, and i read somewhere that i could make an adapter to used it in A4000, it's just a pin setup. Anyone knows about it?

A4000 keyboard port and CD32 serial port are the same. You can plug an A4000 keyboard in and it will work on the CD32 without any modifications.

I can't remember if the A4000 keyboard is the same, but A500 and A1200 keyboards all have a chip built into the keyboard that controls the key presses. This could be the issue, as could the keyboard membrane. But the other main keyboard issue is the 2 CIA chips on the motherboard.

I did a quick search, and it's the A4000 is a 6 pin while the DTV is a 5 pin, but i can make an adaptor since the signals are the same, just need to change pins according the pin out. Some one did it with success. I bought a 6 pin male and a 5 pin female from ebay for less then 4 pounds including shipping... i will try it. :yesyes:

Misread your original post. Thought you had said CD32, rather than CDTV. The CDTV has the same keyboard connector as the A2000.
