On a 270c who’s keyboard works (sort of) I Disassembled and cleaned the corrosion off keyboard membrane wire traces with an eraser (while watching The Chiefs fumble the Super Bowl — mistakes were made) :/
In doing so my distracted brain 1) I knocked off the shift lock LED. 2) I also didn’t release the tabs on the 2 keyboard ribbon cable ZIF’s but pulled them out with force being applied by the latches (it was hard to do and I was stupid not looking to see if there was a release)
I’ve reassembled it and now the keyboard it totally unresponsive. The ribbon cables are pushed in all
The way and locked down.
I haven’t tried bridging the led with foil to see if that open kills the keyboard. (Does it?)
Is there a diy way to reattach the led without buying specialized equipment? (I do have a simple soldering iron)
Did I by chance ruin the ZIF sockets by pulling out the ribbon with latches still engaged?
Did the eraser treatment ruin the wire traces?
What do I do at this point? Try to Source a replacement keyboard and see if I borked the keyboard?
