Answer to "PS4 Power Button & Disc Button Unresponsive!"I'm having the exact same problem except I'm not getting any beeps. This happened after disassembling it to replace the thetmal paste and doing a complete cleaning… What sucks is that I can't go into safe mode to try and do any updates, file system rebuilds, nothing. The buttons just won't do anything, I can't put a disc in. I've tried opening it up, taking it apart, reassembling it, 3 times.. somehow ending up with an extra screw the 3rd time. Ugh. I'm super !#^&@@ and I feel like I broke my ps4, trying to fix it and keeping it from frying the cpu.. my thermal paste was toast.. ugh.. gonna go pound my head against the wall.
