Faulty power switch
Dear all, I'm new in this thread.
When the W200S was new I bought several W200S (156D) in China and gave to friends. Now I have one of them here that had a broken digitizer.
No problem, I bought a new front for it and did the "surgery" to change it. It went well I thought but, big but, the power button doesn't work after the surgery.
I can't wake it up or start it from the power button.
The phone and the screen works in that way that I can start it in recovery (volume - and then plug in a USB to a computer). I can also flash the stock firmware to it with SP_Flash_Tool. I have measured on the power switch with a multimeter and it works.
Does anyone have any idea what's wrong and what to do?
EDIT:
Problem solved! It was the power button flex cable. The phone works fine again.
