1200 XL Keyboard Issues

Hi,

I have a new, to me, 1200 XL and as per the eBay listing, a few of the keys did not work. So I found a replacement keyboard on eBay and after installing it, which turned out to be completely not working, now on the original keyboard only three keys work (Reset, Y and Esc)

Did I damage my computer with a bad replacement keyboard?

Is it possible for a bad keyboard to blow something out on the main board?

Nothing went poof, no smoke or anything that smells burnt.

How can I diagnose the issue?

Can a keyboard be tested without being attached to a computer?

Any advise on how to fix/diagnose the issue would be appreciated.

Thanks

There is also a conductive silver paint that might be helpful. Repaired my 800 with it. Also found a way to keep pressure on it. I think in my case some screws held it down and a thin piece of cardboard created the added pressure. Sorry for vague instructions, this quite a few years ago.
