Hello! I’ve tried to research my issue but have had no success. I bought a switch lite listed as “does not turn on”. Opened it up and discovered corrosion damage. After a gentle scrub of all the components it turns on! However, the power button will not work. The volume buttons work, but not the power. I bought a new ribbon cable - same issue, volume works, not powerI swapped the motherboard with a working switch with working power button, same new ribbon cable - same issueSwapped physical power button and the membrane with a known “working” lite - same issue The only thing I can think of is a warped shell that’s not allowing proper contact with the ribbon cable. What are your thoughts? I’m stumped. Especially with the motherboard swap. Thank you in advance
Alright, y’all. The verdict is in. Apologies in advance for how long it took me (life and shipping delays got in the way)It was in fact the long ribbon cable that connects the two boards together. (Thank you @devnol) The unsuccessful troubleshooting I did prior was: Replaced the smaller board for the righthand buttonsReplaced the power/volume ribbon but ultimately was the long ribbon. Thank all of you for all your feedback. I appreciate it.
There are 2 things that may be the issue. First things first. When it comes to buttons on ribbon cables on handheld systems, most ribbon cables use a common ground which would eliminate an unconnected ground. Since the power button does not work but the volume buttons work that eliminates a bad ground. My guess would be that the pin on the connector on the main board may be slightly corroded or the original ribbon cable is slightly torn. I would double check under a magnifying glass or a microscope (if you have one) to see if you can see any broken traces or tears in the ribbon cable as that would cause your issue. The second possibility (less likely) is that the original cable is serially paired to the handheld and if that is the case no other cables would work with it.
