Trying to track "power on" track for Kindle 7
I have an Amazon Kindle Fire 7 Kids sr043kl that I’m trying to fix. The power on button does not appear to be working but the power can be turned on by plugging the device into a USB charger. Once on the device is fine but again the power button will not turn it off.
I’ve opened up the device and removed the motherboard. I can see the power button contacts and I can confirm that there is momentary continuity when the button is pressed (BLUE bit on pic). I have tried jumpering the power contact to a ground to try to emulate the action of the power button but it’s still not coming on, so my next plan is to try jumpering further up the track. Trouble is I can’t see where the track goes.
Does anyone know where the track ends up (I’ve pointed it out in RED below)?
