Brother P touch 85 label maker with BAD keys

This Brother P-touch label maker appears to work okay until you try the bottom row of keys. Will it live to label again?

Thanks for making this video! I had this label maker with the exact same problem and this fixed it!

This is awesome. Thank you for sharing. Great that you show things not going to plan - good to know I am not alone!

Thanks! Had simular problem on p-touch 65. Root cause was a leaking battery which damaged the printed wire board. Although not visable under a microscope, after measuring the connection seemed to be broken. Like you, I soldered an extra wire in parallel to the printed wiring board, which solved the problem.

My P-Touch PT1000 now has the exact same issue. In fact, all of the lower keys stopped working. I'll trouble shoot like how you did it. Great video!

Great troubleshooting video. I'm going to check PCB one more time...
