HP 97 Keyboard issue

[jftman]

AnyOne trace the problem? Mine started doing that but overall all I been doing is working on the gummy wheel.
Before I began that ,on the first day I received it it acted up by not turning off and numbered key side sputtering. Worked initially, put it away then for a brief time no responses on that right side. Then by itself started working.

Well I fixed the card reader and the machine wasn’t turning off.
I started to disassemble the keyboard level thinking the switches are similar to ho67. Believing I could clean the contacts.

While I tried to maneuver the keyboard apart I gave up because it looked as though if I flipped it out, seeing a ribbon cable from the top, at the display I figured I would stop, not knowing how to proceed, and spray tge switch with CRC, safe for plastic.

Behold the switch is now working, but the whole right side of the keyboard is nonresponsive.

What might I try now?b I am hoping someOne has solved this issue given it happenes and also is frustrating!

I believe the card reader ribbon cable is inserted enough. I followed the procedure of pulling it out of the slot and testing the card reader before full assembly. I hope it is not now so old that it did not like being bent much.

Is there any connection through that bridge board, and might I be able to find a replacement ribbon cable? Just throwing out tge process of what I did. Pic of ribbon cable into the card reader.
