I’ve been using my PO33 for just under a year now but it has recently stopped writing patterns or recognising the write button at all.
I’ve previously had an issue with buttons not working which I solved with the old disassemble and clean solution but this has not fixed the problem in this instance.
The frustrating this is I cannot factory reset or even restore backups as they all require the write button to work.
What’s more confusing is that when I try to manually bridge the contact points (a trick I learned when I found out about the cleaning solve) they don’t seem to work either. My fear is that something internal has broken or I need to de-solder and re-solder the button.
Anyone else have this problem? Any other things I should try first?
