Flex is cheaper for repair..
If you already expirienced screen malfunction, keys (front/dpad) not working sometimes, front camera sometimes don't work or automatic light sensor (brightness level) errors then is bigger probability that it's flex cable.
Either way, if you don't know how to open your Play, maybe it's better to give it to some repair shop (or anything similar you have in your city) because it's most likely hardware issue.
You can try to flash stock firmware, to see if it's software issue (but that will reset your data and apps)
