Hello, I recently bought a Madcatz TES+ and I'm having an issue with the LB/R2 button being shown as always being pressed. It seems like this person https://support.focusattack.com/hc/en-us/articles/115001863283-TE2-and-TE-S-stuck-input-issue-fix
had a similar problem and concluded that defective diodes were causing the buttons to stay active.
I wanted to ask if anyone knew which specific diode might be causing my problems, or had any other advice, before I get to randomly guessing which diode to desolder. Thanks in advance!
