Having an issue with a AY-AT kit. It does not want to stay powered on after pressing the encoder down. If I keep it held down, it works fine, but cannot be used (it shows menu, does test but cannot select anything while holding encoder down). I've replaced the transistors 9014 x2, 9012 on the left side of the board thinking maybe a transistor was bad, but no help. I've replaced the LED, no help. Changed the software, no help. Not too sure exactly where I should be focusing my attention. It is obviously not doing something involving getting the transistors to hold the on state, which I guess should be done via one of the atmega pins going low(?) after pressing the button to keep it on then high when it shuts off? That is just a complete guess based on pretty much nothing, But I'm not 100% sure of what to look for exactly. I could probably figure it out if I gave it some more time, but I figured I would ask in case someone else has experienced this and already knows the fix, save myself some time.
I don't think I broke anything putting it all together, I did lose the original LED though and I read through the thread and found it is important, however, I tried shorting and replacing it with a couple different LEDs with no help. Any assistance is appreciated. Thanks!
