A few weeks ago, my sprint TP2 started to experience Sleep of Death occasionally. However, recently it won't be able to show the screen at all. If I remove the battery and put it back on, the screen is on but when I turn it off, it will never turn on. I tried many Roms include Mr.X and 6.1 rom but none help. I think there might be a problem with the proximity sensor but I don't know how to check it. Anyone know how to fix this? Thanks a lot.
