Atari 800xl Key Repair

[foxmulder900]

Any tips on repairing these keys? It's the only one on the board that doesn't register, so I just de-soldered it hoping to just be able to clean up some corrosion or something. However it doesn't seem to want to come apart any further and I don't want to force it for fear of breaking it.

I measured resistance on non workin one and it was around 100-150Ohm. How much is yours?

I then sprayed some contact cleaner in the litle holes. No change. Then I desoldered it. Suddenly it measured 0Ohm. Heat (and possibly cleaner) fixed it. I soldered it back, job done.

Cleaning plus heat works wonders.

That worked! I just used some contact cleaner and was getting 0Ohm (not sure what it was before), re-soldered and all is well. Thanks a ton!

Does anyone have any of internal key white plastic actuator for an 800XL, please?

I discovered my 800XL suffered from a loft shuffle!
