Update... After snipping off 1mm of ribbon cable I can confirm all buttons are working now. Thanks Crossbow, that was a top tip and really appreciated. Seems that the end of the ribbon just needed “refreshing”. Thanks Nop90 for the conductive pen suggestion but I decided not to go with it but It may well work for anyone else experiencing the same issue as me. Thanks again.

Update... I’ve included a picture which probably explains my problem. I tested continuity and the circuit is fine in all respects including the d-pad left direction to a point. Its a complete circuit to the transparent part toward the end of the ribbon but not right at the tip. As the picture hopefully shows a few carbon contacts are worn away either through my excessive cleaning or reinserting of the ribbon. Crossbow, you mentioned I can snip off 1mm to reveal fresh contacts. Is this my next move or is this flex circuit beyond repair? Thanks.

That’s a lot to be going on with. Thanks so much for all the information. I’ll start working my way through it asap and let you know how it goes.

Thanks Crossbow. I was hoping to contact you as one of your previous posts was on this topic. Regarding marking the d-pad, It never moved in the dismantling process but I’ll keep it in mind. Ive not done a meter test, that’s something I should have thought about. I’m afraid when It comes to ground points you’ve lost me. Electrical diagnostics are a nightmare to me. Perhaps that’s why I’ve hit a wall now. I’ll update shortly.

Hi everyone. Ive read all the forum posts here about D-pad issues but here’s the background... I’m currently trying to solve a problem of just one button not working on my Lynx II after installing a BennVenn rev6 and new speaker. Everything works perfectly except for the left direction on the d-pad doesn’t work. Ive cleaned (with alcohol) the ribbon connector that enters the motherboard and reseated it countless times to try and get the button to work. I’m sure the button was working fine before I opened it up. The only possible visual cause could be a minor kink in the flex circuit that seems to be caused as it sits over a certain bit of plastic on the shell. A few have said that the flex circuit must be seated “perfectly”. Can anyone define “perfectly” as surely it just sits where it sits without fine adjusting. Thanks for any help. Tom
