Long story short, my iPhone 4s power/stand by button went faulty on its own. This problem tends to happen to many iPhones shortly after the 1 year warranty is over. So I bought myself another power button from ebay and proceeded to change it myself. The Power Button Proximity Light Sensor Flex Cable was what had gone bad. This resulted in the power button being stuck and would not work. So I changed it successfully. When I put the battery back and turned the phone on, the white screen appeared. I only see a white screen, no logos or anything. Any suggestions would be greatly appreciated. P.S. I don't want to go to apple and pay $149 to get my phone replaced with a refurbished one when I can just pay $199 to get a brand new iPhone 5 from my carrier.
